Issue 2 — 2004 FiberSpectrum 3

This has been a year of progress within Andritz,followed by excellent market acceptance.Valued customers have trusted us with morecomprehensive orders than ever before in ourhistory — as a result of our ability to integratecomplementary acquisitions into a "full-line"capability from the woodyard to finished pulpbales. We have delivered complete stockpreparation systems and deinking lines as wellas tissue production systems. By efficientlyintegrating our acquisitions, we have been ableto capitalize on inherent synergies to bettermeet customer requirements.

Single-line dependability

The "single line" mill has firmly taken hold,since redundant or repetitive smaller systemsincrease capital and operating costs. "SuperSize" lines with 3000 t/d digesters (Veracel,Brazil), 4700 tds/d recovery boilers (Wisaforest,Finland), and 3200 adt/d pulp dryers (Hainan,China) are now appearing around the world.

Andritz's full-line strategy and highly reliableequipment are preferred by customers. Themost recent examples are the award of a fiber-line (including pulp drying/baling) and chemicalrecovery systems from CMPC's Santa Fe millin Chile, and a complete pulping line, includingrecovery, for Andra Pradesh Paper Mills inIndia. We would not have been able to com-pete for these projects without the efficientintegration of AhlstromMachinery, ABB Fläkt,Lamb, and others.

Reduced capital cost

One consistent require-ment from customers isthe need to drastically

reduce their capital costs and to improve thestart-up curve to quickly reach full production.Our efforts have centered around simplifyingsystem designs, utilizing global sourcing,manufacturing in the most efficient geogra-phies, and standardizing system componentswhile maintaining high product quality stan-dards. We introduced dynamic simulation(IDEAS) tools for DCS check-out and opera-tor training. This has contributed to shorterstart-up curves.

Customers, too, have a remarkable impacton capital costs: from their selection of proj-ect partners (individual equipment or EPC) tothe specification of equipment (standard mod-ules or new designs).

Recent examples of standardization includethe 9.3 m wide dewatering and pulp dryinglines including cutter/layboy and baling.Another is the PrimeLine™ tissue productionsystems (5.4 m+ at speeds over 2000 m/min).Modularization still permits customization, butallows us to reduce engineering hours anddevelop quality sub-suppliers — driving theoverall cost down.

Service partnership

The formation of European Mill Service (EMS),a joint venture between Rheinhold & Mahla of Germany and Andritz, gives mills a servicealternative as they consider their outsourcing

options. We candemonstrate savingsin maintenance costs of 20% over threeyears with thisapproach, combinedwith our OPE® con-cept — while improv-ing a mill's overallproduction efficiency.

A message from Andritz P&P Management

Pulp&Paper

Overcoming the "bark with a bite" at Valdivia

In January 2002, Celulosa Arauco y Constitución S.A. chose Andritz tosupply a complete woodyard, black liquor evaporation plant, and whiteliquor plant for its Valdivia mill in Chile. One of the big challenges mas-tered by Andritz was the handling of eucalyptus and its unique bark.

C e l u l o s a A r a u c o

The Arauco Group is a leadingChilean pulp, wood, sawmill and panelboard company in Chile andArgentina. Its new Valdivia greenfieldpulp mill cost US$1.2 billion andbegan operating in February 2004.

Andritz worked closely with Araucoduring the technical and commercialphases of the project. Valdivia MillManager José Vivanco explains,“Because the Andritz technical scopewas clear and easy to follow, the wholenegotiation process went smoothly.”

Following a successful start-up,Vivanco confirms that all Andritz systems are operating as expected and have already exceeded design production levels.

The Valdivia woodyard

The Valdivia project con-tains several new featuresthat are designed for aworld-class mill producing600,000 t/a of ECF pulp.There are two debarkinglines, chipping, storage,screening, and bark han-dling. "It looks like a nor-mal set-up for a wood-yard," Timo Palo, AndritzProject Manager forwood processing sys-tems, explains, "but theinsides are different."

The eucalyptus challenge

The “insides” are different to accommo-date the species mix at Valdivia. Pulpproduction is 60% pine (Pinus radiata)and 40% eucalyptus (a mixture ofEucalyptus globulus and Eucalyptusnitens). Arauco is now harvesting euca-lyptus to produce 1900-2100 adt/d pulp(1700 adt/d for pine).

Arauco chose Andritz to supply thewoodyard due to its firm belief that Andritzcould supply cost-efficient, competitivequality equipment, according to Vivanco.

“Eucalyptus presents unique chal-lenges,” Palo says. “The bark is longand stringy like rope. Instead of com-ing out of the debarker at designatedslots, it comes out with the logs. AndEucalyptus nitens is even more difficultthan Eucalyptus globulus. It bends likerubber and knots like dreadlocks!”

José Vivanco, Mill Manager at Valdivia.


The relationship between Andritz andArauco began in 1991 when Andritzsupplied two pine debarking lines. Inpreparation for the Valdivia project,Arauco allowed Andritz to conductexperiments on their eucalyptus line.

The PowerFeed™ drum infeed con-veyor feeds entire 6-7 m2 unbarked logbundles directly into the debarkingdrum. Eucalyptus and pine logs, shortand long, are treated separately. Thevariable speed of the PowerFeed™ and

the debarking drum provide the flexibili-ty to handle different logs. If the logsare difficult to debark, the control sys-tem can increase the speed of thedebarking drum and/or reduce thespeed of the PowerFeed™ conveyor.

The two debarking drums use a normal “tumble” de-barking method for2.44 m logs and a parallel debarkingformat for 6 m logs, according to Palo.Rotational speed can be adjustedaccording to wood quality and speciesfrom 3-7 rpm.

EucaRoller™ to the rescue

Between 20-30% of eucalyptusbark is removed in the debarkingdrum. The remaining bark comesout of the drum with the logs andis extracted by the EucaRoller™.

The EucaRoller™ is an Andritzinnovation that removes theremaining bark through engi-neered gaps between strategi-cally placed rollers. It has reverseand shaking rollers to move thedebarked logs sideways. Thisenables the loose eucalyptusbark to fall through the gaps.

“The EucaRoller™ worksextremely well and delivers fulldebarking capacity to the line,”Palo says.

HHQ-ChipperTM

centerpiece

The Chipper is the centerpiece ofthe woodyard because it has themost influence on the chip quality– the foundation for good pulping.Andritz’s horizontally fed HHQ-Chipper™ systems are success-fully fulfilling this role at Valdivia.

“The chippers produce qualitychips for us at the required highcapacities,” says Vivanco.Eucalyptus is again a challengefor the chipper, since it is a veryhard, rough wood. In addition,eucalyptus has a low pH-value(acidic) which promotes corro-sion in open-air conditions.Stainless steel replaces typicalmild steel in the construction ofthe chipper system to prolongthe working life. The twoAndritz HHQ-Chippers™ atValdivia can process both long(6 m) and short (2.44 m) logs,but are ideal for the longer logs.

Timo Palo, Andritz Project Manager forwoodyard systems for the Valdiviagreenfield project.

The EucaRollerTM is an Andritz innovation to removestringy eucalyptus bark prior to the chipping operation.

Special equipment for shredding and fiber recovery

Eucalyptus bark requires special knivesfor shredding its bark. Andritz providedthe equipment for bark treatment –including the hammer-type shredderwhich effectively treats the bark so thatit can be burned in the boiler as biofuel.

Another Andritz innovation for fiberrecovery — the breakage and log recov-ery system — helps Arauco minimizewood losses. “Our losses are minimal

because of the system,” Vivanco says.“It filters out the bark on its way to theshredder and can rescue wood over 0.5 m long for chipping. The recoveredwood is then sent to a chipping line to rejoin the process.”

Chip storage and screening

The chip storage facility at Valdivia has100% active volume and consists oftwo longitudinal chip piles storing andreclaiming four different chip species.

According to Vivanco, “The chip storagearrangement and reclaiming gives usthe flexibility we need to maintain chipinventories and feed the digester withthe right chip quality at the right time.”

At Valdivia, rectangular chips arescreened by two CS 1000 screens witha combined capacity of 2000 loose m³/h.Each screen has decks for “oversize,”“accepts,” “pins,” and “fines.” The latterare sent to the boiler. The “overs” aresent to the HQ-Sizer™ for processinginto the correct size for cooking.

The HQ-Sizer™ replaces re-chippers,crackers, slicers, and conditioners withone unit. It splits the larger chips hori-zontally into the required size. In prac-tice, 80% of the “overs” are convertedinto accepts with minimal pins and fines.

Another contributor to the system’sflexibility are bypass options for reducingdowntime and maintaining production. Ifneeded, one or both screens and/or theHQ-Sizer™ can be bypassed and chipssent straight to the digester.


Andritz Scope at Valdivia

Wood Preparation Plant(Started up November 2003)

The Andritz woodyard consists of atwo-line debarking and chipping plant.PowerFeed™ conveyors, 5.5 x 35 mdebarking drums, EucaRoller™ sys-tems, and HHQ-Chippers™ areinstalled in parallel. The debarkingplant also has bark treatment withbark shredding and water treatment.Chip storage is handled with TravellingScrew Reclaimers. Chip screening isperformed with two gyratory typescreens. Oversized chips aretransformed into acceptablechips with an HQ-Sizer™.

White Liquor Plant(Started up February 2004)

The plant produces 7600 m3/d of white liquor. It started up onschedule and exceeded nominalcapacity within two weeks of thestart-up. The recausticizing plantincludes X-Filters™ for greenliquor filtration and a CD-Filter™for white liquor filtration. Both fil-ters represent the first of this fil-tration technology in operation inChile. Also included was a mod-ern LMD Lime Kiln equipped witha Sector Cooler. The Lime Kilnhas a capacity of 545 t/d of burnt lime.

Evaporation Plant (876 t/h)(Started up February 2004)

This is the first complete Andritz evap-oration plant delivered to Chile. Thefiring liquor produced in the Andritzcrystallizing concentrators is 78% drysolids and the liquor is stored in apressurized storage tank. The 6-effectlamella-type evaporators have internalsegregation technology and an inte-grated stripper. The methanol gas fromthe stripper is handled in the liquefac-tion plant also delivered by Andritz.

The Andritz evaporation plant at Valdivia removes 876 t/h of water and delivers 78% dry solids black liquor to the recovery boiler.


Working closely

Arauco and Andritz signed theproject contract in January2002. By November 2003, thefirst wood processing trialswere taking place at the mill.The woodyard was officiallyhanded over to Arauco inJanuary 2004. All of the criticaltraining of operators and main-tenance personnel was con-ducted by Andritz. The debark-ing plant control system fromAndritz also contributed to asmooth start-up. "Operatortraining is easier when hard-ware and software come fromthe same supplier," says Palo.

For Arauco, the team approachwas one of the keys to success."The project was carried outunder the full supervision ofAndritz technicians workingclosely together with construc-tion and Valdivia mill personnel,"Vivanco says. "We consider it a

very good example of cooperation atwork. We are satisfied that problemsare solved quickly and we get verygood technical assistance when weneed it."

Another innovation that Andritz is stillputting in place is a system for remotemonitoring so that the Andritz WoodProcessing experts in Finland can beconnected to the Valdivia mill. This ispart of Andritz's OPE® (OverallProduction Efficiency) service. Theonline system will gather process datato assist in optimization and problem-solving activities as needed.

Vivanco is very proud that Araucocurrently operates the highest capacitydebarking plant for eucalyptus in theworld. "The Andritz system gives usflexibility in debarking eucalyptus and/orpine in both lines," he says.

"The biggest and the best environmentaland energy equipment available today"

Requiring 22.5 months from breaking ground to start-up, UPM-Kymmene took a step into the future with itsmodernization and expansion at Pietarsaari. This is the world's largest single-line chemical recovery plant —and all Andritz technology. The recovery boiler has 600 MW biofuel firing capacity, with virtually no fossil carbon dioxide emissions.

U P M - K y m m e n e

Inside the Andritz recovery boiler — the world'slargest at 4450 tds/d. The boiler operates athigh pressure (92-102 bar) and high-tempera-ture (492-505°C). Steam generation with inter-nal circulation is 205 kg/s. A higher power-to-steam ratio increases power generation by 10%.


"Very seldom do any of us have anopportunity to set a world record —especially not with the press of anelectronic button. It is a great honor to be able to participate in the settingof a productivity-boosting record!"

Those were the words of MattiVanhanen, Finnish Prime Minister, ashe and top management from UPM-Kymmene celebrated the completion ofthe world's largest chemical recovery

system. The ceremonytook place August 24, 2004in Pietarsaari. Mill techni-cians gave Vanhanen anelectronic panel with a single button. When hepressed it, the new Andritzrecovery boiler was rampedup to recover a world record4700 tonnes of dry solidsper day (tds/d).

Wisa 800

The modernization project,named Wisa 800 by UPM,puts the Pietarsaari pulp,paper, and energy complexin top form. "Through thisinvestment in Wisa 800, wehave strengthened our pulpself-sufficiency and havemoved into an elite catego-ry in terms of energy andenvironmental perform-ance," says Vesa Vainio,Chairman of the Board ofUPM-Kymmene.

UPM mills use about fourmillion tonnes of pulp annu-ally. Before the Wisa 800project, the company pur-chased about 10% of itspulp. After the project, pur-chased pulp requirementsare minimal.

On the cost side, thetechnology of the world'slargest recovery boiler andthe single-line chemicalrecovery process willreduce production costs significantly.On the environmental side, in spite ofthe fact that pulp production increasedby 200,000 t/a to a total 800,000 t/a,fossil carbon dioxide emissions arereduced to being almost non-existent.All other environmental targets set forthe mill are also clearly achieved.

UPM purchased the black liquorevaporators, recovery boiler, and whiteliquor production plant in cooperationwith Wisapower Oy, a subsidiary of the Pohjolan Voima energy group.Wisapower owns the new evaporationplant and recovery boiler, while UPMoperates and maintains them.

Andritz supplies best available technology

Andritz was responsible for the recoveryisland equipment — evaporation plant,recovery boiler, recausticizing plant, andlime kiln — in addition to the new sawdustpulp cooking plant. Andritz also modern-ized one of Wisaforest's pulp drying lines.The delivery was additionally supplement-ed with simulation equipment for recoveryboiler operation developed by Andritz.

The start-up of the chemical recoveryline in April 2004 was a great success,and exactly within schedule.

"The best available environmental andenergy equipment was sought for thisproject," says Matti Lievonen, President,Fine and Specialty Papers Division withUPM. "Thanks to this equipment, pulpmill effluents have decreased in spite ofthe increased pulp and energy produc-tion. The fossil carbon dioxide emissionsare close to zero, and the energy fromblack liquor combustion satisfies therequirements of all production plants inthe mill area."

An attitude of openness

"One thing above all is that we playedwith an open deck," says Heikki Öhman,Technical Director and Project Director."We put all of our cards on the tableand agreed on solving all problemsjointly. To identify potential problemsearly enough, we agreed to quicklyinform each other about any conflictswe learned about."

"From our side, we are proud of thetrust UPM placed in Andritz," says MarkkuHänninen, President and CEO of AndritzOy. "UPM challenged us to do our best.They are skilled implementers of invest-ment projects. In a project of this size,problems are bound to surface, but wewere always able to arrive at joint solu-tions to the benefit of both companies.

"It was very rewarding to us thatUPM was prepared to utilize our newest

and best technology, which is nowworking well. By managing risks, UPMbenefits from the latest technology.Some of the chemical recovery line is'pioneer' equipment. Yet, with all thistechnology and scale, the start-upoccurred right on time — and the start-up curve has been amazingly steep.This is quite an accomplishment."

After the completion of the chemi-cal recovery project, UPM rewarded key suppliers who delivered the bestperformance, according to criteriaestablished within the company. AriNieminen, Andritz Project Director forWisa 800, and his project team wereselected for the "Best Start-up Imple-mentation" award.

The white liquor plant supplied by Andritz is the world's largest at 10,000 m3/d of whiteliquor production. Lime mud for the kiln is separated, washed, and dewatered in aspecial disc filter, the Andritz LMD-Filter™ (above), which is new Andritz technology.Markku Lankinen (left) of Andritz and Kaj Nordbäck, Power and Recovery PlantManager at Pietarsaari stand in front of the new filter.

The most advanced evaporator plant in the world is operating at Pietarsaari. Suppliedby Andritz, the plant evaporates 1050 t/h of water and produces firing liquor at 85%dry solids using a Liquor Heat Treatment Concentrator.

An acid test for the LMD-Filter™

Nieminen cites one of the more inter-esting strategic investments for bothUPM and Andritz — the decision byUPM to select the LMD-Filter™ in thewhite liquor plant.

Andritz had developed a new conceptfor drying lime mud, the LMD-FilterTM, inwhich mud is separated and washedwith a special disc filter. Due to thehigh capacity requirements of the pro-cess, Wisaforest would have normallyrequired two large drum filters to sepa-rate and dewater the lime mud. How-ever, this would have been costly interms of invested capital and also thespace required.

"It was an example of risk-taking byboth Wisaforest and Andritz," saysNieminen. "Wisaforest was willing totry new, conceptual technology and wewere able to stand behind it and guar-antee its performance."

Pilot tests proved the concept. "Wewent from pilot runs directly to worldrecord production," Nieminen says.

In fact, perhaps the LMD-Filter™ per-formed too well. "After start-up, weobserved that the lime mud going tothe kiln was too dry, which increasedthe temperature of the flue gases,"Öhman says. "This affected the opera-tion of the electrostatic precipitator. Wedecided to add moisture to the limemud after the filter. Now we mustadjust somewhere else in the processto be able to benefit from this ability tomake highly dry lime mud."

Bioenergy super-efficiently

Pietarsaari is a good example of the syn-ergy between a forest products plant andan energy producer. Ahlholmens Kraft,which now is the world's second largestbio power plant (550 MW/240MWe) afterWisapower, is situated adjacent to themill. It utilizes all locally generated bio-fuels to generate power. The poweralso satisfies Pietarsaari's need forheat, electricity, and steam.

Working while celebrating

The day that Finnish Prime Minister MattiVanhanen pushed the button to set aworld record for black liquor combustionwas a day of celebration. It was also"business as usual" as this massive millproduced another 2285 adt of pulp —while the recovery boiler fired a peakload corresponding to 4803 tds/d.The potential electricity production ofWisapower (140MWe) makes Pietarsaaria significant bio power plant — with its1150 MW of biofuel firing capacity and380 MW of electricity production.

Tailor-made sawdustcooking for Wisaforest

Pietarsaari's sawmill produces approx.100,000 m3 of sawdust each year. Itused to be burned for energy, but withthe Wisa 800 project, UPM decided toproduce pulp with it.

Conventional sawdust cooking isrough on the fiber. UPM asked Andritzto develop the cooking process to gentlyand slowly cook the fibers – maximizingpulp strength and yield.

Andritz has supplied sawdust digesterssince 1967, according to Kai Lindroos,Fiberline Sales Director. Test runs and lab-oratory research at Andritz, UPM, and theÅbo Akademi University in Finland yieldeda process very suitable for Wisaforest.

The cooking process at Pietarsaaristarts with an impregnation stage per-formed at low temperature in an M&DDigester. Then a separate digester fin-ishes the cook and the pulp is washedin a DD Washer. Design capacity of theline is 200 t/d.

"This is tailor-made for UPM's condi-tions," says Lindroos. "It ensures thatthere is no degradation when the sawdustpulp is added to the hardwood pulp."

Plates full of performance at Powell River

For cost and efficiency reasons, NorskeCanada shut down the wood-room, groundwood mill, and kraft mill at Powell River. This put thespotlight directly on the TMP mill. Working with Andritz, the TMP millwas able to boost capacity and quality with no capital investments.The results are exceeding expectations.

NorskeCanada operates four mills inBritish Columbia as well as WesternCanada's largest paper recycling facility(see column at left). After acquisitionsthat formed the company in 2001, themills (Crofton, Elk Falls, Port Alberni,and Powell River) underwent a programto avoid overlaps and exploit synergies.

Murray Jones, now Director ofOperational Excellence at Powell River,was at that time appointed "synergychampion" for manufacturing. "In 2002,I was part of the group responsible forimproving our company's manufacturing

efficiency," Jones says. "We had anurgent need to find new ways of doingthings to remain competitive."

The focus at Powell River was onpulp supply. The kraft mill (vintage1960's) was too small for cost-efficientproduction and was shut down.Closed, too, were the woodroom and

groundwood mill which weretoo costly to operate. The millwould now rely on purchasedchips for its TMP mill, whichwas started in 1975.

Before the changes, PowellRiver's TMP mill produced anaverage of 650 t/d from fivelines. When Jones asked whatwas the maximum that couldbe produced on a sustainedbasis, the answer came back,"810 tonnes per day."

"That's a bit short of the 950tonnes per day our three papermachines consume when infull production," Jones thought.“We have to do more!

"The TMP mill at Port Alberni(sister mill) was way ahead of

us in adopting new refiner plate designs,"Jones says. “Compared to Port Alberni,we had a gap of 300 tonnes per daybetween our installed horsepower andwhat we were getting out of the TMP mill.That's the tonnage we needed."

NorskeCanada

NorskeCanada’s Powell River Divisionproduces newsprint and hi-brite publication papers. Total output is459,000 t/a of paper products, madeprimarily from high quality TMP.

NorskeCanada is the largest papercompany in Western North America,the world's largest producer of direc-tory papers, one of North America'sleading producers of groundwoodprinting papers, and also operatesthe largest paper recycling facility in Western Canada.

It was formed from the roots ofBritish Columbia Forest ProductsLimited, which was acquired byFletcher Challenge and later (2000) by Norske Skog. Norske Skog alsoacquired Pacifica Papers, which wasformed from the paper assets ofMacMillan Bloedel. With the acquisi-tion of Pacifica, the company assumedthe new identity of NorskeCanada and

became a publicly-traded company,with Norske Skog today owning aboutone-third of the shares.

NorskeCanada operates four millsand one paper recycling division inBritish Columbia. Headquartered in Vancouver, total sales are about C$ 1.6 billion.


N o r s k e C a n a d a

"That was then, and this is now!"

"Ed Antolovich has a focused way ofdoing things that I admire," Jones says."He is the main person, from my per-spective, who took the challenge andmade it work with his team."

When NorskeCanada was formed,Antolovich was named TMP OperationsSpecialist. When presented with thechallenge of increasing TMP tonnageand quality, he moved his team into thesame building (they called it the "Pod")so they could interact and reviewprogress on a daily basis.

"We didn't have a real need tochange before," Antolovich says,"because with the groundwood andkraft mills, TMP was putting out what itneeded to. Also, with the closures, welost our most experienced operators toretirement. This may have been ablessing. Experienced operators getinto a comfort zone. They typicallydon't push the equipment to get theextra tonnage, for fear of pluggingsomething or causing a breakdown.

"But, that was then, and this is now.It's as much about changing cultures asit is about changing equipment. Today,we hold our morning production meet-ings in the control room so our opera-tors are completely involved."

The TMP mill

The TMP mill consists of five lines.Lines #1 and #2 have Bauer* 52-inch485/489 Double Disc refiners of 1970'svintage. Lines #3 and #4 have BauerB-60 counter-rotating Double Discrefiners from 1980. These are the onlyunits of their kind in the world. Line #5,the newest, utilizes Sprout-Bauer*Twin 60 refiners from 1987. The millalso has three Bauer Double Discatmospheric reject refiners.

With no groundwood, TMP wouldhave to replace and compensate forthe 200 t/d of species-specific fiberused in Powell River's specialitypapers. Since kraft would now be apurchased item, the replacement TMPhad to be stronger and brighter tocompensate. For cost reasons, themill wanted to minimize kraft usage.

"So the task was clear," Antolovichsays. "More tonnage, more strength,more brightness from TMP!"

The call to Andritz

"One of the early things we did was to sit down with Andritz," Antolovichexplains. "We explained that we want-ed it all — more tonnage, higherstrength, cleaner pulp, maximum ener-gy efficiency, and no loss in long fiberfraction. And we wanted it fast."

Norm Webster and Luc Gingras fromAndritz/Durametal® became involved inJanuary 2002 and quickly absorbed thechallenge.

"We knew the mill was using 15-to 20-year-old plate designs with little previousincentive to change," says Webster,Western Regional Manager for AndritzServices. "Now, they were motivated totry new things."

Gingras, Product DevelopmentDirector for Mechanical Pulping withAndritz agrees. "We became part ofEd's team to look at the overall TMPoperation and make recommendations.They put their trust in us."

Andritz recommendations came in two areas: 1) general process and oper-ational changes, and 2) a Durametal®

refiner plate upgrade development program.

Powell River operated each of the fiverefiner lines with different freeness tar-gets, ranging from 95 to 220 ml CSF atthe secondary discharge. When a linewent down for any reason, the quality ofpulp would change dramatically.

Andritz suggested setting the freenesstarget for all lines at 135-150 ml CSF.This immediately stabilized the screenroom and the long fiber fraction on allfive lines, rather than having to dependupon Line #5 for most of the long fiber.

Next was to replace the old refinerplates with new Durametal® technology.Webster, Gingras, and others fromAndritz met with the mill regularly over an8-month period to develop a plate devel-opment program together, implementthe changes, and monitor the results.

A leap of faith — no time for trials

"Typically, when you propose new platedesigns to a mill, they order one set andrun a trial," Gingras says. "Then, theymay order another trial set and analyzethe results before deciding to convert.This process can take months."

Not so at Powell River. "Durametal®

has a great reputation and holds severalpatents," Antolovich says. "They gaverecommendations for each plate posi-tion, we agreed, they manufactured theplates, and we ran them. What theyrecommended worked, and we didn'twaste a lot of time."

Finding the limits

"Our approach was to maximize refinerloads and total production by reducingthe specific energy per tonne of pulpproduced," Antolovich says. "We want-ed to use all the energy available to usin the most efficient way possible."

Step-by-step, each production linewas pushed to its production limit whilestaying in the pulp quality guidelines.Bottlenecks were eliminated. Newattention was given to the online pulpquality monitoring system that had

been in the mill, but had not been reliedupon. According to Randy Wagner,Process Control Specialist at PowellRiver, "We eliminated manual testing sothe operators would rely on the onlinemeasurements."

Wagner reviewed key data to find therange of normal operating values.From this, he wrote predictive modelsso operators could adhere to a "90% ofmaximum" target for each productionunit. The "90% of maximum" ruleapplies everywhere. For example, elec-tric motors (with typical 15% reserve factors) are operated at 103% of capacity(90% of 115%).

"The stability of our refiners is probablythe best in the company," Wagner says."We max out the motors on Line #5 at18 MW (15 MW motors) and yet thestandard deviation of load swings isincredibly low. We have a very smoothoperation.

"Our goal is to run our assets to the lim-its without breaking them," Wagner says.

Plates make a difference. TMP MillwrightEd Westgate puts new Durametal® plates onLine #5.

Production improved substantially

Durametal® engineers coupled newinner plate designs that promote stablechip and pulp feeding with outer platedesigns that improve pulp quality.

"Once our operators got used to thenew plates and realized they could pushthe refiners without blowing them up, wereally ramped up," Antolovich says.

For Lines #1 and #2, the newDurametal® plate designs achieved an8% production improvement and 7%improvement in tensile, along with theincrease in freeness level. Specific energywas reduced an average of 300 kWh/t."We push the line harder than we everhave and don't encounter twin screwfeeder issues since the installation ofthe new plates," says Antolovich.

In 20 years of operation, Lines #3 and#4 never achieved full production capac-ity due to their sensitivity to vibration,which limited the maximum closingpressure that could be tolerated. NewDurametal® plate designs stabilized thefeeding of chips and the pulp and steamflows. This reduced motor load varia-tions. Long fiber content increased from

20 to 30% leading to greater tensileindices (from 3817 to 4397 m).

"We took production on Line #5 from300 to 380 tonnes per day, an increase of 26%, and lowered freeness from 220to 145 ml CSF," Antolovich says. "Be-fore, we couldn't load the refiners past13-14 MW on the primary and 11-12 MWon the secondary. Now we run 18 MWon both. Our peak production has been450 tonnes per day out of this line.Since we put in the new plates, we'venever had to take the blowline down toclean it. We used to plug it on a regularbasis, because of steam handling inthe refiners."

Can plates really make a difference?

According to Antolovich, "Once weproved to the operators that the Andritzrefiners and Durametal® plates could takeit, they began to push — and they haven'tstopped since. The plates were the cat-alyst, but the culture change with theoperators has made a huge difference.

"We had an event where we ran out ofplates and had to put the old plates backin," Antolovich says, "and we went rightback to where we were before. High free-ness, poor fiber strength, poor operation,blowline plugs. So, these plates havemade a tremendous difference for us.

"Overall TMP production increased20% with a tougher species to pulp,requiring higher energy," says Antolovich."We now use zero kraft on two of ourmachines. No new capital equipmentwas needed. That tells the story."


Plates for performance

At Powell River, low energy/highperformance refiner plates wereemployed. Durametal® inner platesthat promote stable chip and pulpfeeding were coupled with outerplates that improve pulp quality.

"Powell River began to see immedi-ate advantages with the new plates,"Norm Webster of Andritz says."Things like variable pitch and feedinjectors began to pay off quickly."

"These designs are proven inmills," says Luc Gingras. "We addmore bar edges to the plate byextending the outer plate diameter(overhung) and by making the barsthinner. This lowers the intensity ofthe refining. For better steam han-dling, we give the bars a small netpumping angle which moves pulpmore quickly through the refiningzone. This lowers energy require-ments. The design is optimized todirect steam away from the pulp flow,leading to more stable motor loads."

26% increase in production. Afterinstalling new plate designs, PowellRiver took production on Line #5 from300 to 380 t/d and lowered freenessfrom 220 to 145 ml CSF. Peak produc-tion has been 450 t/d out of this line.



A world’s first at Yueyang

China is the second largest producer of paper in the world. In order tosatisfy domestic demand, it imports huge quantities of recycled paperand market pulp each year. Tiger Forest and Paper Group is a companythat is developing its own sources of high quality fiber with the help ofthe world's first P-RC APMP pulping line and an Andritz woodyard.

T i g e r F o r e s t a n d P a p e r G r o u p

The Yueyang Paper Mill in Hunanprovince is situated on the shores ofthe Yangtze River, China's largest. Themill is rapidly becoming one of the mostimportant in China, manufacturing arange of paper grades from high-yieldfiber furnishes including annual crops.

In 2003, the company installed amodern woodyard, the first of its kind inChina, in order to supply its AndritzAPMP pulping line and a new 100,000 t/aAndritz P-RC APMP pulping line.

The attributes of a Tiger

The former Yueyang Paper is now oper-ating under the new name of TigerForest and Paper Group. According toGroup Vice General Manager and ChiefEngineer, Mr. Zhang Dong Ji, "We believeour company embodies the attributes ofthe tiger, being very sensitive to its sur-roundings (the market and the environ-ment). It is also strong and flexible,delivering the right product for emerg-

ing market demands."Since the late 1980's,

the company has beenplanting 500,000 Mu(33,000 ha) of trees forpulpwood. Speciesinclude slash pine, loblollypine, and poplar. Theseplantations can be seenon either side of the six-lane highway that runsfrom Guangdong toBeijing passing throughthe Hunan capital on itsway north. Yueyang is theprovince's third largest citywith excellent connectionsby road, rail, and river tothe rest of China.

"Putting something back"

In talking with Mr. Zhang Dong Ji, youvery quickly become aware that he is apaper industry enthusiast. He talks freelyabout his company's pulp and paper-making capabilities and his own person-al plans for the future development ofpaper and board production in Hunan.

"In the past, our industry in Chinaconsumed raw materials that we pur-chased on the open market," Mr. ZhangDong Ji says. "We recognize that wehave to operate sustainably, puttingsomething back and not just taking

away from the environment. Threeyears ago, we extended our sourcing toinclude the plantations that we havenurtured in surrounding areas."

The selection of advanced mechanicalpulping technology fits also into the sus-tainability picture, Mr. Zhang Dong Jinotes. The higher yields of mechanicalpulping systems compared to chemicalpulping systems and the flexibility of the

process enables Chinese mills to getthe most benefit from precious planta-tion resources.

At present, locally grown poplar isused for various end products includingnewsprint, LWC, and printing/writinggrades. The poplar originally camefrom Italy and grows very rapidly. Theregion around Yueyang has good fertilesoil, an annual rainfall of 1200-1400 mm,and strong sunshine. Winter lasts fromNovember to March, but temperaturesseldom fall below freezing. This resultsin a tree diameter of 20 cm at chestheight within five years, when the firstcommercial cut can be carried out.

Yueyang's woodyard includes anAndritz dry debarking-chipping line.Logs are fed through the debarkingdrum and then to the Andritz HQ-Chipper™. The chipper is gravity-fedand has a capacity of 105 m3 sub/h.According to the mill, it produces homo-geneous chips. The chips are screenedwith an Andritz CS-type screen and con-veyed to the storage silo, which uses aCenterScrew™ slewing screw reclaimer.

"The Andritz woodyard equipmenthas run perfectly from the very begin-ning," Mr. Zhang Dong Ji says. "It givesus the necessary chip quality for thepulping process."

The Yueyang Paper Mill is situated on the shores of China's largest river, the Yangtze,in the province of Hunan. Shown here are incoming logs to be debarked and chippedin the Andritz-supplied woodyard.


First there was APMP

The first Andritz mechanical pulping lineat Yueyang was installed in 1995. The lineis based on Alkaline Peroxide MechanicalPulping (APMP) tech-nology and produces200-220 CSF pulp forthe mill's offset bookpaper production at a today's productionrate of 120 t/d.

Mechanical pulp-ing of high-densityhardwoods requiressome degree ofchemical pretreat-ment to develophigh-strength prop-erties and reduceenergy consumption.There are severalchoices in pretreatment processes, but alkaline peroxide is a preferredmethod for the locally planted poplarby Yueyang.

In addition to the APMP line, there is abatch kraft pulp line with a capacity of130 t/d and a line that produces 120 t/d

of kraft pulp from reeds. Also, the millhas a traditional groundwood line pro-ducing 70 t/d and a new 400 t/d DIPline installed last year to supply thenew PM8 paper machine.

Then a world's first — P-RC APMP

The APMP process completes most, orall, of the chemical treatment before refin-ing. Often, this places some limitationsin opacity and light scattering ability. TheYueyang Mill was the first in the worldto install the new Andritz P-RC APMPtechnology, which maximizes chemicaland mechanical efficiency in developingthe optical properties of the pulp.

"Andritz first introduced APMP intoChina in 1989 and this new P-RC line isthe first installation of its kind in the world,"says Mr. Zhang Dong Ji. "Now we seemany other mills following our example."

The P-RC APMP line at Yuyang pro-duces pulp with 90-100 CSF freenessfor the production of LWC grades. It isdesigned for 300 t/d production. Andritzprovided, among other parts, primaryand secondary refiners, two low-consis-tency post refiners, and one reject refin-er. "The new P-RC APMP technologyis working very well," says Mr. ZhangDong Ji. "It has already exceeded itsdesign production of 300 tonnes perday since starting up in September 2003


The P-RC APMP process

The process consists of mild temper-ature Preconditioning (P) of alkalineperoxide treated chips and RefinerChemical treatment (RC) to carry outsome of the bleaching reaction. Themain difference between P-RC andtraditional APMP is that the P-RCprocess has a High Consistency (HC)retention tower after the primaryrefiner. This makes it possible to domore Refiner Chemical treatment forbetter optical qualities of the pulpand to better utilize the residualchemicals for brightness.

With its inter-stage HC tower, theP-RC APMP process has more flexi-bility in controlling pulp propertydevelopment. It can even be run likeconventional APMP by changing theprocess conditions for the chemicalreactions prior to refining. With lowchemical applications, the processcan develop properties close to SGWpulps; with more chemicals, theprocess is able to produce pulp simi-lar in tensile to most hardwoodBCTMP pulps at a lower specificrefining energy input.

and has reached all guarantee valuesand quality targets.”Mr.Zhang Dong Ji says that, "The P-RC

APMP process has resulted in our mak-

ing a product with an average bright-ness of 80 ISO, sometimes reaching 85,for LWC and printing/writing grades,depending on wood species being used."

Production of APMP short fiber fromthis line accounts for about 45% of thepulp for Yueyang's LWC grades (58, 60,64, 70, and 80 g/m2). "We are movingtowards 54 g/m2 and our target is 48 g/m2," Mr. Zhang Dong Ji says.

Slush pulp from the P-RC APMP ismixed with market pulp from Canada anda proportion of DIP (20-40% dependingon grade) to provide the furnish for PM8.

Long relationship with Andritz

"We have a long relationship withAndritz and we have done a lot of trials

at their R&D facility in Springfield, Ohio(USA)," says Mr. Zhang Dong Ji. Logswere even sent from Yueyang planta-tions to Springfield for trials.

"Trials proved that the Andritz tech-nology would enable us to reducechemical consumption by some 20%and still achieve the quality we want-ed," Mr. Zhang Dong Ji says. "TheAndritz team and our engineers workvery closely together. The service wereceived during start-up and optimiza-tion was very good. We are satisfiedwith the quality of the engineering andif there are any problems Andritz hasbeen quick to come up with solutions.They are very good at problem-solvingand we could not ask for more."

Tiger Forest and Paper(formerly Yueyang Paper) is a state-

owned shareholding company that

was established in the year 2000.

The company was issued ISO 9002

certification in 2000, and has since

been awarded a number of National

Quality and Environmental accolades.

It also won a product quality award for

its Yueyang Tower 49 g/m2 offset

newsprint brand.

In addition to the Yueyang mill's four

machines producing 132,000 t/a, pro-

duction was increased through the

start-up in July 2003 of the new PM8.

This machine is capable of producing

either 580 t/d of high quality newsprint

or 715 t/d of LWC grades.

Mr. Zhang Dong Ji said that it was

planned to

increase the capacity of the mill to

about 600,000 t/a by 2007. "We would

like to get into the liquid packaging

board business, but this is for future

development. The Tiger Forest and

Paper Group has four mills in the

Hunan province of which Yueyang is

the largest. We are planning on

expanding the Yuan Jiang Paper mill.

The project is expected to add some

100,000 tonnes per year in capacity."

Breathing new lifeinto Kingsport

Weyerhaeuser rebuilt its Kingsport mill essentially "from the ground up."A gleaming new continuous fiberline from Andritz started up in August2003. This, and a new paper machine, make Kingsport a world benchmarkfor low cost free-sheet production. "It's as technologically advanced asany in the world," says the fiberline manager.

W e y e r h a e u s e r

Kingsport is like a lot of smalltowns in America. Perhapsprettier than most, due to thesurrounding Appalachian andGreat Smoky Mountains. Alsounique in another way — it hasa large, yet virtually odor-free,pulp and paper mill near itstown center.

The mill, an important part ofKingsport's economy, was onceowned by Mead, later Willamette,and, through acquisition, nowWeyerhaeuser. Weyerhaeuser,one of the world's largest inte-grated forest products compa-nies, recently completed a majormodernization that, accordingto all concerned, "rebuilt themill from the ground up."

A great deal of pride sur-rounds the "new" mill. The con-struction project logged 6.2 mil-lion work hours without a lost-time accident. It was complet-ed on time, on budget. And,Weyerhaeuser's investmentbreathed new life — and a sta-ble future — into the mill.

The Kingsport story is one of hard-working employees"managing enormous change,"according to Jeff Chamberlin, FiberlineDepartment Manager. "It is also a storyof becoming one of the world's lowestcost free-sheet producers with a fiber-

line that is as technologically advancedas any in the world."

But, the story might have had a muchdifferent ending.


"I have a lot of respect for the people who workhere." Jeff Chamberlin, Fiberline Department

Manager, has seen the Kingsport workforce go

through significant change. "They have a great

work ethic. They care about what they do. They

have experience, maturity, and good sense. We

started up this new pulp mill without a single lost-

time injury — and that is really amazing."


The old batch mill

Not so long ago, things atKingsport were not nearly aspositive. The mill, operatingsince 1916, began to see hardtimes in the mid-1990's.Employees and the communityknew that the mill might beclosed any day.

"If you go through the old pulpmill, you'll see six ancient batchdigesters with manual cappingvalves," Chamberlin says. "Therewere panels where operators hadto turn dials to manually adjustthe speed of a washer. Beforethey replaced the recovery unit,Kingsport had one of the oldestoperating Tomlinson recovery fur-naces (circa 1948) in the world."

Enter Willamette Industries in1995 when they purchased themill from Mead. Chamberlin, aWillamette veteran, explains,"The strategy was to breathenew life into the mill with strate-gic investments."

Willamette began by makingmodest improvements. Then, in2002, it announced its decisionto invest nearly $500 million tobring the mill in line with its otherlow-cost and environmentallysound mills.

A pause — and renewed commitment

In November 2000, Weyerhaeusermade a bid to acquire WillametteIndustries. There was considerableconcern in Kingsport. Where did themill fit into the new owner's futureplans? Would the investment atKingsport be cancelled? Everyoneknew that, without modernization tomake the mill competitive again, therewas little hope for the future.

Thankfully, Weyerhaeuser strongly

supported the investment decision —maintaining that Kingsport positionsthe company to capture and holddomestic market share even againstimports from low-cost centers such asBrazil and Indonesia.

Responding to challenges

Chamberlin came to Kingsport fromWillamette's "Marlboro" (Bennettsville,South Carolina) mill in December 2002when the fiberline project was in earlystages of construction. "When I gothere," he says, "it was tough with limitedmanpower to keep the old mill running.

Weyerhaeuser's Kingsport, TNmill is near the center of town,adjacent to the South HolstonRiver. Local citizens appreci-ate the virtually odor-freepulping process.

"We've come a long way." Scott Tipton, Fiberline

Shift Supervisor, has worked at the mill for 16 years.

"I started here in the labor pool providing help wher-

ever needed. I've done most of the jobs in the old

pulp mill — digester, brownstock, bleach plant. It

was exhausting work. Then I became a foreman.

It was tough to keep the old mill running while they

were building the new fiberline, but we did a good

job. When the transition came to the new mill, it was

very smooth. The continuous digester was com-

pletely foreign to me. The DD Washers just run.

The equipment and the technology are just great."


"At the same time, we were trying to geteveryone trained to run the new mill.

"I really respect the people who workhere. They have gone through an awfullot. I've seen how well they respond tochallenges and stress. We have one ofthe oldest average age workforces with-in the Weyerhaeuser system — about56 years old. All of a sudden, they hadto grasp all this new technology. And,they had to do it while keeping the oldmill running up until the final minutesbefore the switchover."

A safe project, on budget,ahead of schedule

Over the years, Willamette earned areputation as a builder of low-cost, effi-cient mills by managing projects withinternal resources rather than outsideengineers and construction firms. Thiscapability transferred seamlessly toWeyerhaeuser.

Design and engineering for Kingsportwere provided by Weyerhaeuser Engin-eering Services (WES), with help fromits construction management group.According to Howard Irwin, Area Con-struction Manager at the time, there were1800 workers on site at the project'speak. The project broke ground in July2000 and was completed in four phases.

The woodyard was relocated andupgraded first. The new paper machinestarted up in August 2002. A newrecovery boiler started up in October2002. A lime kiln (relocated from anoth-er mill) and recausticizing equipmentstarted n May 2003. And, the newAndritz bleached hardwood fiberline andrebuilt ClO2 plant, started up August 7,2003 — two weeks ahead of schedule.

"By the time we got to the fiberline,we had tuned ourselves up very well,"Irwin says. "We picked the best sub-contractors and labor."

Although the equipment it uses is the same as that in a kraft pulping and

bleaching process, Kingsport's adapta-tion of the cooking technology is one ofthe industry's first and is thought to bethe only one of its kind in North America."The chemistry enables us to be differ-ent and better," says John Sanders,Assistant Fiberline Manager.

"From day one of my career, I alwayswanted to go through a start-up andsee everything from breaking ground tothe finished plant," says Sanders. "Weall were aware of the time commitmentrequired during a project of this magni-tude. Basically, we were all working 80-and 90-hour weeks for a year leading upto start-up. We had heard horror storiesfrom other mills about this continuing formonths after start-up. But, that didn'thappen here. Things went that smoothly.

"The plan was to keep the old millrunning until the new fiberline couldconsistently make 400 t/d. We tried toprepare ourselves for having half thecrew in the old mill and half the crew inthe new mill. In the end, we knew wecould not staff both mills. So we shutdown the old mill and immediatelycame over and started the new fiber-line. And, we never looked back."

Sanders was impressed with theteamwork. "The Andritz guys weworked with on this project were veryknowledgeable and focused on our suc-cess," Sanders says. "I don't think wewould have started up on time if it wasn'tfor them working as hard as they did.They pushed us and did an excellent job.

"This start-up is an experience that Iwill value forever."

The hardwood fiberline

The hardwood fiberline has a designcapacity of 925 adst/d. The digesteruses single-vessel hydraulic cookingtechnology. There are control strate-gies to compensate for the fact thatlignin removal is not as aggressive withKingsport's cooking chemistry.

The chip feeding system is based uponAndritz TurboFeed® technology (see box

to right). A Diamondback® chip bin is usedfor uniformly pre-steaming the chips.

The screen room consists of a pri-mary knotter close-coupled to threestages of screening and one high-den-sity cleaning stage. Knots and rejectsare washed of good fiber beforeremoval from the fiberline system.Accepts from the primary screens aresent to a pre-thickener and washed in atwo-stage DD Washer before moving toa two-stage oxygen delignification sys-tem. Another two-stage DD Washerperforms post oxygen washing beforethe bleach plant. The three-stagebleach plant also uses DD Washers forinterstage and final pulp washing.

"The differences between the oldmill's pulp and our current pulp is thatnow it's cleaner and around one pointbrighter," Sanders says. "The fiberlineproduces a strong fiber that mixes wellwith the softwood kraft pulp used in thepaper machine's furnish."

Feedback from the paper mill

"I talk with the paper machine peopleevery day," Chamberlin says. "That's a big part of my job. The new papermachine has not produced a single tonof off-spec paper that could be attrib-uted to pulp mill quality."

The new paper machine, dubbed K-1by the mill, replaced three older papermachines and started up in August2002. It produces uncoated free-sheetin a variety of roll sizes, brightness,basis weights, and recycle contents.

"This machine has the potential tobe the flagship of Weyerhaeuser,"Chamberlin says. "It has tremendousavailability and efficiency. Its produc-tion is already among the highest inthe company. Our pulp is certainly afactor in its success."

Turbo-ized chip feeding.

Weyerhaeuser Company's linerboardmill in Albany, Oregon was the first in the world to install the revolution-ary new chip feeding system for continuous digesters — the AndritzTurboFeed® system.

TurboFeed ® transfers chips from thechipmeter directly to the top of thedigester using specially designedpumps instead of the traditional HighPressure Feeder (HPF). Based uponthe success at Albany, the Kingsportmill installed a TurboFeed ® system,with three chip pumps in line.

"I was very skeptical when they toldme it would pump chips all the way upto top of that digester." says ScottTipton, who many years ago was thechip filler for the old batch digestersat Kingsport. "I'm a believer now.They pump with no problem."

By eliminating the HPF and otherequipment, mills obtain significant sav-ings in capital, installation, operating,and maintenance costs. Recently, millsin Brazil and Chile have also orderedTurboFeed ® systems — including theworld's largest single-line continuouscooking plant (3000 t/d capacity).

chip pumps at Kingsport.



"A great pulp mill"

What is Chamberlin's view of the fiber-line start-up? "Water in, liquor in, chipsin, and we were making on-grade pulp.We have never sent any off-grade pulpto the paper machine."

Weyerhaeuser believes it has techni-cal advantages in the Kingsport fiber-line. To do this, they took some calcu-lated risks with regard to the equip-ment, according to Chamberlin. "Forexample, we helped work out the nutsand bolts of the TurboFeed® systemthat had only been installed in oneother mill in the world. The risks wetook are paying off in terms of dollarsfor our shareholders.

"This is a great pulp mill," he contin-ues. "It's high quality. Strength, cleanli-ness, bleachability, brightness, andyield are right where we need them tobe. It's environmentally sound. BODon a per-ton basis is less than half ofthe previous operation. It's extremelyreliable. We just went one month withzero downtime — no shorts, no breaks,no trips, no equipment failures. It'samazingly flexible. We can speed upand slow down as needed to matchproduction of the paper mill."

And, it has room to grow. "Withinthree or four months from start-up wewere running for days at a time at 100%of design capacity," Chamberlin says,adding, "we can run 15% above designand I know we can go higher if needed."

Raising the bar

"This is undoubtedly one of the mostautomated pulp mills in the world," saysSteve Turner, Fiberline Process ControlSpecialist. "We have lots of instrumen-tation and the most automated start-upsequences for operators that I haveever seen."

Turner thinks that Kingsport has "raisedthe bar on the level of automation.

"There is a lot of flexibility built into thisdigester, so we are able to try differentcontrol strategies," he says. "We've real-ly taken the load off the operators when itcomes to tasks like sequencing the startof equipment. Most of the operators hadnever used a DCS before. Now they canconcentrate on production and quality,and not on being computer experts. Thecomputer is fast, consistent, and keepsthe processes stable. Stability meanshigher quality at lower costs."

Improving every month

After the start-up, Kingsport is focusingon three areas: workplace safety, con-tinually looking for ways to lower manu-facturing costs, and employee training.

"Our product quality is improvingevery month," Chamberlin says. "We'renow in the middle of step-up training(one or two job levels up) so employeescan relieve each other for days off andvacations. We're about to embark onthe SafeStart™ program, which is acommon sense approach to safetyusing behavior-based techniques.

"This whole project with Andritz wasexcellent. Whenever there was a techni-cal issue, there was always a knowledge-able resource at Andritz willing to help.There was never a point where weraised our voices. We went through thistogether. The project team and start-upexperts from Andritz were the best."

The Andritz fiberline at Kingsport is designed for 925 adst/d ofbleached stock. It consists of an Andritz Lo-Solids® continuousdigester, screen room with post-screen Drum Displacer™ (DD) Washers, a three-stage bleach plant with interstage DD washing, and a two-reactor oxygen delignification system with post-oxygen DD washing.

Sun Paper — The rising sun in China

Shandong Sun Paper is one of the largest privately-owned paper compa-nies in China. It has 17 paper machines at its mill in Yanzhou City, with atotal capacity of one million tonnes per year. Its newest machine dependsupon an Andritz stock preparation system, the first of its kind in China.

S h a n d o n g S u n P a p e r

Shandong Sun Paper Industry startedmanufacturing paper 22 years ago with asingle machine producing 1 t/d. It was asecond-hand machine and the proprietor,Mr. Li, was not permitted to purchase newmachine clothing. So he used off-cutsfrom the State-run mills.

At the Sun Paper mill in Yanzhou City(two hours drive south of Jinan, the capitalof Shandong province), total paper capac-ity is today over 1,000,000 t/a. Accordingto Deputy General Manager and ChiefEngineer, Mr. Ying Guang Dong, fivemachines (700,000 t/a capacity) makecoated board grades. Three machinesproduce coated duplex board, with a toplayer of 100% virgin fiber and the otherlayers from recycled fiber. The other twomachines make folding boxboard.

The rest of the mill produces printingand writing papers.The new PM19,started up in August 2004, has a capac-ity of 200,000 t/a. A new finishing linewill be started up in August 2005.

Andritz supplied the stock preparationsystem for PM19, the first completeAndritz stock prep line in China. Thissystem features new Andritz Papillon™cylindrical refiners, a thick stock screen-ing plant, and a complete machineapproach system for maximum deaera-tion and final cleaning of the stock, aswell as a CD profiling water system.

"We installed the Andritz Papillon™refiners in our new line at Yanzhoubased upon our successful experiencewith them at the Guangdong Mill," saysMr. Ying Guang Dong.

Sun Paper's mill near Yanzhou City produces over one million tonnes of paper andboard products a year.

Experience gained atGuangdong Mill

The Guangdong Mill, a private joint ven-ture with a local family, produces boardproducts. Papillon™ refiners are utilizedfor refining the bleached hardwood(LBKP) and softwood (NBKP) furnish.Andritz also delivered the pulpers, deflak-ers, broke handling, and board machineapproach systems for all four plies.

"It is the experience we gained from thisstock preparation equipment that prompt-ed us to go with Andritz on the presentproject," Mr. Ying Guang Dong explains.

Mr.Ying Guang Dong has been in theindustry for 20 years, and was trained asa paper engineer. He has been a ProjectEngineer on seven new paper machinesin the past five years. He has also beeninvolved in a number of rebuilds. Hespent 15 years at the Ningbo mill and thelast five years with Sun Paper.

Stock preparation at Yanzhou

Andritz FibreSolve™ pulpers andPapillon™ refiners at Yanzhou are pre-paring stock for three different furnishes:

• BCTMP — 100 admt/d capacity • NBKP — 200 admt/d capacity • LBKP — 300 admt/d capacity

Andritz TC-133 cleaner plant.Thick stock screening system (0.15 mm slotted baskets) at Yanzhou.

Papillon™ cylindrical refiner for the NBKP line (200 admt/d).



There is also an Andritz thick stockscreening system utilizing ModuScreenTM Fpressure screens with 0.15 mm slottedbaskets, rated at 650 admt/d.

White water fiber recovery is accom-plished with an Andritz disc filter.

The machine approach system con-sists of a five-stage cleaning plant, aMulti-Retention Dual Deculator® for com-plete deaeration, and ModuScreenTM HBheadbox screens. A FibreSolve™ brokepulper is utilized under the machine.

"The screening and thick stock clean-ing system supplied by Andritz is workingvery well," says Mr. Ying Guang Dong."We are pleased to the extent we haveordered four additional systems."

PapillonTM

cylindrical refining

"The Papillon™ refiners were chosenbecause of their advanced technologyand very largely because of their lowerenergy consumption," says Mr. YingGuang Dong. "We find that the tear andburst strength of the pulp is an improve-ment over conventional refining."

The unique cylindrical refiner,Papillon™, combines gentle and stablefiber treatment and extremely low ener-gy consumption. It efficiently appliespower to gently refine and develop thefiber. With its small diameter in therefining area, it is much more energy-efficient than conventional designs.

Capacity would be 600 t/d or just

over 200,000 t/a. The company is

looking into the possibility of set-

ting up a joint venture with an

overseas partner.

Shandong province in Eastern

China has a history of more than

5000 years. It is considered to be

one of the significant birthplaces of

Chinese civilization and, of course, it

was Chinese civilization that invent-

ed paper close to 2000 years ago.

Shandong has also been the

home of a large number of histori-

cal figures, whose important influ-

ences are still evident in contem-

porary China. Confucius, the

great thinker and statesman, was

born in Shandong. His teachings

are a pillar of Chinese culture and

have exerted great influence

around the world.
