On behalf of the Board ofDirectors and the staff at CTI, Iwould like to personally thankthose of you who attended the2004 Committee Workshop at Vailthis past July. As most will agree,that meeting was one of the mostproductive workshops we havehad in recent times. We dealtwith many important topics suchas Certification and the Program

for the upcoming Annual Conference in San Antonio. As wehave mentioned in the past, changes are taking place andthey are changes for the good of the industry.

We also wish to take the opportunity to extend an invitationto the 2005 Annual Conference in San Antonio, Texas onFebruary 26th through March 3rd. We will again hold ourconference at the Westin Riverwalk Hotel. When we werethere a few years ago, we found the hotel to be veryaccommodating to our conference needs. The locationprovided us with easy access along the Riverwalk to allrestaurants and attractions. San Antonio has been developedinto a beautiful city to visit and hold a conference.

Within the CTI organization, we are presently expelling muchof our efforts towards our Programs. It is our goal to be an

Consider yourself invited to CTI’s 2005 Annual Conference inSan Antonio, Texas.

Your program committee would like to invite you and your company to the2005 Annual Conference, this year held in San Antonio, Texas. This is oursecond time to hold our conference in this wonderful city located West ofHouston at the foot of the hill country.

The city of San Antonio is full of heritage and culture with many interestingthings to see and do. Along with the outstanding location we have a greatprogram lined up for you, we have a full offering of information, educationand an opportunity to participate in some of the ongoing work on standardsand codes.

We believe it is our responsibility to make sure what we have to offer youcan share with others at your company. Because of our mission to be a non-profit technical organization weare charged to bring the most timely and latest information in the industry.

We have 23 papers being presented in a (new) concurrent format on Monday. Water Treating will have onesession and P & T and ES & M will have the other. This is a new approach for us, and we hope you will findits benefit, with our trying to add more to our programming.

We will offer an extended time for committee work to be done.In past winter meeting we had only a very short amount oftime set aside to do the committee work. This year we haveallowed much more time to do the work so important to theCTI. Please refer to the CTI news for times and committee andwork to be done.

organization that not only establishes and maintains thestandards for the industry, but also educates the industry.We believe that we are moving forward toward that goal.The upcoming Annual Conference for the first time will offerconcurrent technical papers. There will no longer be only (1)choice of papers to attend in a given time slot. Thesetechnical papers will be presented the first day of theconference with the remaining 2-days reserved foreducational formats that will promote participation from allattendees. You will need to review the agenda to determinewhat peaks your interest most. We are excited about thischange in format. We have been locked in to a mundaneprogram for too many years and as we promised, changes areoccurring.

We hope that you will make the CTI Annual Conference oneof your meeting choices for 2005. We promise to provide avariety of information relating to the Refining, Petrochemical,and Power Markets as well as the HVAC. As always, ifanyone should have any comments or suggestions, pleasecontact the CTI Office direct just give me a call.

8:45a - 9:15aTP05-01 - Optimization of Water Cooled Chiller – Cooling Tower Combinations -James W. Furlong and Frank T. Morrison, Baltimore Aircoil Company

James W. Furlong is Vice President, Comfort Cooling at Baltimore Aircoil Company.Mr. Furlong holds a BE in Chemical Enginnering from Manhattan College and anMBA from Loyola University. He is a member of ASHRAE.

Water cooled chiller systems have typically been designed around enteringcondenser water temperatures of 85°F with nominal condenser water flow of

3 GPM/ton and a 10°F range. In recent years there has been considerable debate on themerits of designing around lower nominal condenser water flow rates with a higher rangein order to improve system lifecycle costs. However, two other parameters must also beconsidered in any analysis – approach and design wet bulb. The question to be answeredis: What nominal condenser water flow rate and approach is best from a first cost standpointas well as from full load energy standpoint at any given wet bulb? A study was recentlycompleted in an effort to answer this question using actual first cost and full loadperformance data from a variety of chiller, cooling tower, and pump manufacturers fornominal 500 ton water cooled, centrifugal chiller system. This paper reports on the findingsfrom that study.

9:15a - 9:45aTP05-02 - Online Refurbishment of Four Large Natural Draft Cooling TowersAlex Dreyer, GEA Aircooled Systems and Gerrit Putter, SASOL Technology

Alex Dreyer graduated with a Ph.D (Mech. Eng) from the University of Stellenbosch(near Cape Town), South Africa in 1994. He has been involved in thermal design andengineering since 1988. His involvement included contracted research work in the field ofevaporative heat and mass transfer, general heat transfer related consulting/contract

work and the development of engine cooling systems, automotive air conditioning and intercoolingsystems for various commercial/military vehicles. Alex joined GEA Aircooled Systems in 1997where his responsibilities includes the design and construction of large industrial evaporative anddry cooling systems.

Many large power/petrochemical plants have older cooling towers which are in need of majorrepairs but shutting down these towers will result in large production losses. A project was startedin which the water distribution system and the splash pack grids of four existing natural draftcooling towers at a large petrochemical plant were to be replaced without shutting down the waterflow to the cooling towers. The water flow to typically 10% of a given tower was shut off after theinstallation of butterfly valves. The existing packing in this area was then removed and replacedwith new high performance slash packing. The work on the first two towers is scheduled forcompletion in July 2004. Performance tests on these two towers are scheduled for the southernhemisphere summer 2004/2005. The work on the remaining two towers is scheduled for completionat the end of 2005.

8:45a - 9:15aTP05-13 - Evaluation into the use of Mine Drainage to Supplement Cooling WaterAmitha Harriram, Dr. A Harriram and D.G. Nieuwenhuis, Sasol Technology

Amitha is currently a senior scientist at Sasol Technology, Water & EnvironmentTechnology (WET), Secunda. The WET group at Sasol is a Research division that isresponsible for the identification of new opportunities and improvement of currentsystems around water, ash and effluent streams. She joined Sasol 2 years ago fromthe University of Durban-Westville where she completed a Phd in Chemistry. Amithahas attended and presented at various local and international conferences. She has

2 international publications from of her MSc and has submitted a further three for review on herPhd.

The Sasol petrochemical complex located in Secunda, South Africa operates the world’s largest coalto synthesis gas conversion process. Expansion projects have resulted in an increase in coolingwater requirements which is difficult in this water short catchment. Conversely, drainage watercontinuously accumulating in old coal mine workings is a growing liability. In an effort to balancethe supply and demand within the complex, investigations were initiated into the use of mindrainage water. The mine drainage contains amongst others, elevated concentrations of Calcium (~250 mg/l), Magnesium (~ 150 mg/l), and Sulphate (~ 2,955 mg/l) as well as trace quantities of ironand manganese. The addition of up to 12% of such mine drainage water to a cooling medium couldtender the blend highly conducive to fouling, scaling and corrosion. Pilot scale cooling towers wereoperated over a twelve month period and the results including the limitations observed will bediscussed.

The dissipation of ambient or process heat in large HVAC systems, manufacturing facilities, powergeneration plants, refineries, metal mills and forges, chemical plants and food processors is mostoften accomplished by cooling towers. These simple structures facilitate the transfer of unwantedenergy (heat) from a transport liquid (usually water) to the atmosphere. The bane of coolingtowers, with relation to efficient heat transfer and pathological risks to employees is suspendedsolids. These solids can originate in the process, in the piping, from the atmosphere or from internalbiological growth. Side stream filtration is the most commonly used methods of maintainingminimal suspended solids in the cooling system. Present day systems rely mainly on two establishedmethods of suspended solids removal. The first utilizes cyclonic principles and can remove onlyhigh specific gravity solids leaving organics such as algae behind. The other method is granularmedia filtration that generally requires very high volumes of flush water during its cleaning process.This filter type also accumulates particles of high specific gravity within its housing causing theeventual costly replacement of its media. Both of these methods require high energy inputs tooperate. Automatic self cleaning screen filter technology not only removes both organic andinorganic solids regardless of specific gravity but also requires very little energy to operate andconserves coolant additives by using very little coolant liquid for the self cleaning process. Byincorporating the cleaning cycle into the blowdown process of the cooling tower system theunwanted loss of coolant can be completely eliminated. This manuscript will address the operationalprocesses of automatic self cleaning screen filtration technology and review a number of real world

The veil thickness rangedfrom no veil to 13mils and revealed no advantage for increasing the veil thickness. Strongwell alsoperformed another environmental study on the impact of coating for the bearing and compressiveproperties. The water exposure was at room temperature and 125°F revealing no performanceadvantage obtained from the coating.

10:30a - 11:00aTP05-04 - Natural Frequency Characteristics of Drive ShaftsRobert Poling, Amarillo Gear Company

Robert Poling has a BS in Mechanical Engineering from Texas A&M University. After working in the auto industry in Michigan for two and a half years, Robertreturned to Texas and is an engineer at Amarillo Gear Company. Robertspecializes in gear drive and drive shaft design and finite element analysis

For rotating machinery utilizing drive shafts, it is important to operate at a speed sufficiently lowerthan the drive shaft’s natural frequency to prevent destructive vibration. In this paper, the theoryof determining the shaft’s natural frequency is presented as well as methods for empirically testinga shaft’s natural frequency. Vibrations levels in the region of the natural frequency are empiricallydetermined for composite drive shafts and multiple test methods for determining the naturalfrequency are described and compared. The effect of the end conditions is discussed and anappropriate end condition is presented, and finally, the effect on natural frequency when a torqueis applied to the composite shaft if presented.

11:00a - 11:30aTP05-05 - Atmospheric Emissions from Evaporative Cooling TowersWayne Micheletti, Wayne C. Micheletti, Inc.

Evaporative cooling systems are common elements in many industrial processes, ranged frommanufacturing to power production to refining. Because these systems can use large amounts ofwater, discussions of potential environmental issues usually focus on water intake or wastewaterdischarge concerns. However, atmospheric emissions from cooling towers can also be importantconsiderations. This paper reviews the major environmental regulations governing atmosphericemissions from cooling towers and examines some of the ways in which associated permit limitsmight influence cooling tower design and operation.

Pressure recovery is an effect that occurs in gas and liquid flows. It concerns the conversion fromboth the speed of the fluid into pressure and into the inverse direction under ideal conditions. Infact, it is the consequence of one of the most fundamental physical laws (i.e. the law of conservationof energy). Although an air-cooled heat exchanger, the velocity of the air varies many times,pressure recovery effects have been hardly recognized up to now. This report aims to discuss theeffects on air-cooled heat exchangers and the further impact of it on the dimensioning of axial airflow fans for those air-cooled heat exchangers.

Introducing a new breed of yellow metal corrosion inhibitor that will revolutionize the way coolingtowers are treated. This new inhibitor forms a protective film on the metal surface hat is unequaledin its resistance to breakdown. The film is so durable that it is capable of maintaining corrosionprotection for weeks without the presence of residual inhibitor in solution (a feat that azoles areincapable of achieving). This paper will present detailed studies that compare the new inhibitor toazoles, demonstrating how the advantages of the new inhibitor will provide cost, environmental,and application benefits to the user.

Bacteria are everywhere in recirculating cooling water systems. Controlling bacterial populationsin the bulk water and on cooling system surfaces is necessary to maintain and operate the coolingsystem properly. Control of micro organisms in the field requires successful application of biocideagents. However, bacterial resistance to biocides is inevitable and irreversible, a natural consequenceof bacterial adaptation to exposure to anti microbials. This paper presents mechanisms of bacterialresistance to anti microbials, strategies for overcoming resistant cell populations, and a supportivecase history using biocides successfully against resistance bacteria.

With decreasing water supplies in most industrialized areas of the United States, cooling waterdischarges are being studied for potential reuse applications. Serious concerns exist among potentialreuse water recipients due to the perceived content of this water. Health concerns and aestheticconcerns impact any reuse decision. One key way of alleviating these concerns and making quickdecisions concerning the quality of the water is using real time analytical instrumentation. Advancesin online testing and online instrumentation allowing quick decisions about the quality of thesewaters. This paper will discuss the analysis of these waters and instrumentation that allows carefulmonitoring to be achieved.

Over the past several years, the frequency of fan air flow testing to verify new or existing fanperformances in cooling towers and air-cooled heat exchangers has increased. Whether for new orreplacement fans, customers want to verify that they are getting all the performances they werepromised by the fan manufacturer – (i.e. does the fan air flow test meet or exceed what the fanmanufacturer predicted). Proper fan air flow testing, while not an exact science, can usually spellthe difference between a satisfied or unsatisfied customer. Two fan testing methods – one for wetcooling towers and one for air cooled heat exchangers – will be discussed in detail as well asexamples given of actual performance versus predicted performance.

Over the past fifteen years, there has been a marked increase in the number of lightning protectionsystems being installed on cooling towers. These systems, meant to last twenty or more years, arefalling into disrepair from six to twelve months after completion. This is occurring due to variousissues including, but not limited to, vibration, chemical environments, improper use of components,and incomplete installations. Because of these issues, the creation of a lightning protection standardspecific to cooling towers should be created to both correct these deficiencies on future projects aswell as upgrade existing systems.

11:30a - 12:00pTP05-18 - Low Cost Cooling Tower Biocide AlternativesAbdulaziz Turaik, and David Evans, Saudi Aramco

Abdulaziz R. Al-Turaik is a Chemical Engineer working in the Dhahran UtilitiesDepartment of Saudi Aramco, the world’s largest oil company. Mr. Turaik earned hisBachelor of Science in Chemical Engineering from King Fahad University of Petroleumand Mining in Dhahran, Saudi Arabia in 1998. He is a member of the Saudi ArabianWater Environment Association.

Saudi Aramco’s Dhahran Utilities department is concerned about both biocide cost and biocideperformance for the operation of its seventeen cooling towers (40 cells). The department testedalternative biocides and is now using an effective low cost biocide. Slug dosing calcium hypochloritewas used for many years for microbiological control on the cooling towers. The cost of the calciumhypochlorite was relatively low, however, when it was slugged dosed, the calcium hypochloriteoxidized expensive anti scalant, reducing heat exchanger protection. Therefore using calciumhypochlorite had a high overall cost. The department tested non oxidizing biocides to eliminate theanti scalant oxidizing problems. The non oxidizing biocides worked but they cost twenty timesmore than calcium hypochlorite. Also, the cooling tower operators did not like the safety concernswith non oxidizing biocides. The department successfully tested and is now using a low costbiocide that is normally used for swimming pools. Testing included microbiological test to confirmthe biocides effectiveness.

Effective microbiological control is a critical component to optimizing efficiencies in industrialcooling water systems and oftentimes the most difficult to achieve and maintain. Due to a widerange of reasons involving environmental discharge issues, worker safety concerns, storage,troublesome feed equipment and impact on system metallurgy, the selection and/or application ofmicro biocides is becoming typical. A novel non chemical means of maintaining total systemmicrobiological control has been successfully developed and effectively applied to industrial coolingwater systems. The process involves the unique and practical application of ultrasound andprovides both planktonic and sessile biological control. This paper describes the treatment processas well as the advantages and benefits achieved by maintaining system cleanliness.

2:30p - 3:00pTP05-20 - Reducing Cooling Tower Costs with Ozone TechnologyAndrew Conner, Cleanwater Ozone Systems, Inc.

Graduating with a degree in Control Systems Engineering from the U. S. Naval Academy,Andrew Conner laid the groundwork for a future in water system design. After completinga successful 9-year career in the Navy, he’s now working toward his ProfessionalEngineering license while acting as an assistant designer for CleanWater Ozone, in FortWayne, IN. The company designs and installs a wide range of ozone treatment systems

for water and wastewater treatment, including systems for cooling towers. He and his wife,Heather, are celebrating the birth of their third daughter this year.

Maintaining high water quality within a cooling tower is an operator’s biggest struggle in keeping anefficient, healthy tower. Conventional water maintenance methods include chemicals and regularblowdowns. Ozone technology however, is the fastest growing challenger to conventional treatment.Ozone, the most powerful commercial oxidizer available, has the ability to disinfect tower water,reduce scale, and significantly decrease the amount of blowdown water. From midsize corporateoffice buildings to NASA’s Kennedy Space Center, operators are finding that ozone technology hasthe ability to reduce costs substantially over chemical treatment.

For nearly thirtyyears, the CoolingTechnology Institutehas provided a trulyindependent, thirdparty, thermal perfor-mance testing ser-vice to the coolingtower industry. In1995, the CTI alsobegan providing anindependent, thirdparty, drift perfor-mance testing ser-vice as well. Boththese services areadministered through the CTI Multi-Agency Tower Performance Test Program andprovide comparisons of the actual operating performance of a specific towerinstallation to the design performance. By providing such information on a specifictower installation, the CTI Multi-Agency Testing Program stands in contrast to the CTICooling Tower Certification Program which certifies all models of a specificmanufacturer's line of cooling towers perform in accordance with their publishedthermal ratings.

To be licensed as a CTI Cooling Tower Performance Test Agency, the agency mustpass a rigorous screening process and demonstrate a high level of technicalexpertise. Additionally, it must have a sufficient number of test instruments, allmeeting rigid requirements for accuracy and calibration.

Once licensed, the Test Agencies for both thermal and drift testing must operate infull compliance with the provisions of the CTI License Agreements and TestingManuals which were developed by a panel of testing experts specifically for thisprogram. Included in these requirements are strict guidelines regarding conflict ofinterest to insure CTI Tests are conducted in a fair, unbiased manner.

Cooling tower owners and manufacturers are strongly encouraged to utilize theservices of the licensed CTI Cooling Tower Performance Test Agencies. The currentlylicensed agencies are listed below.

The following questions were sent through our website to the “Ask The Expert” Committee. This is just asampling of the types of questions we get from those of every walks of life. Thanks to the committee the CTI is ableto reach out in another way to help those in the industry and those who have interest in our industry.

Question 1 - About the ATC-105 sitetest: In order to do this test as it should be and in order to reach CTI-certification, Iassume this test is only valid if performed at full load . Please confirm or elaborate .

Reply to Question 1The CTI has two thermal test programs.

The ATC-105 Test Code is used to measure the thermal performance of a specific tower at a specific site to determine if isperforming in accordance with the purchaser’s contract requirements. The tests are a one-time event for the individual tower andthe results are usually not applicable to other similar towers. The CTI has five licensed test agencies that can perform tests inaccordance with the ATC-105 test code. Cooling Tower Test Associates is one of the five licensed test agencies for ATC-105 thermal performance tests. The test limits for an ATC-

105 field test on a specific tower are:

• Water flow: +/-10% from specific design• Fan motor power: +/-10% from specific design• Wet bulb temperature: +/-15 degrees F (+/-8.5degrees C)of specific design• Cooling Range: +/-20% from specific design

The CTI also has its STD-201 Certification Programfor a line of towers with a number of similar models.My company is the exclusive agency for reviewingthe design data, performing an initial qualifying testand performing annual reverification tests. Toparticipate in the CTI Certification program requiresseveral activities prior to the initial qualifying test.These include submitting physical and thermalperformance data on all of the models in the line tobe certified. These models and thermal performancedata are reviewed for consistency between themodels in the line. If the review is successful, a modelis selected for the initial qualifying test. Usually Iselect one or two alternate models in case all modelsare not available. The test can be performed at themanufacturer’s test lab if they have one or at acustomer site. The test data are collected using theprocedures given in the ATC-105 test code but theanalysis of the data is in accordance with the STD-201. After a line of towers has obtained its initial CTICertification, an Annual reverification Test is requiredon a different model to retain the CTI Certificationfor the line. The test limits for a STD-201 certificationtest are:

• Process fluid flow: +/-40% from midpoint ofpublished rates for unit being tested(with propernozzles for uniform flow distribution)• Fan motor power: +/-10% from rated power ofunit being tested• Wet bulb temperature: 60 to 90 degrees F (15.5 to32.2 degrees C)• Cooling Range: 4 degree F (2.2 degree C)minimum• Cooling Approach: 5 degree F (2.8 degree C)minimum• Process Fluid Temperature: 125 degrees F (51.7degrees C) maximum

If a manufacturer has a customer test that must beperformed for contractual purposed, it may bepossible for me to also use this for a certificationtest.

The CTI web site www.cti.org has some informationabout the STD-201 Certification Program and a slidepresentation that can be downloaded.

Our company web site www.cttai.com has additionalinformation about the CTI STD-201 CertificationProgram and related test information. It also has acopy of the FSP-156 pre test bulletin which can bedownloaded that is useful in preparing for either anATC-105 or STD-201 test.

Question 2 We have 50 kg/cm2 pressure producing steam at rate of 50 t/hr. We areusing phospate program to control pH. The blowdown rate is 2 m3/hr and I want to knowif this blowdown can be used as cooling water make up for cooling tower and if yes thenhow? Please explain in detail.

Reply to Question 2Typically boiler blowdown water is not used as make up to a cooling tower. Blowdownwater usually contains a high amount of dissolved solids which can contribute tocorrosion in the cooling water and depending on your boiler water treatment programcan contain phosphates which are used in the boiler water for scalecontrol, which in a cooling tower can precipitate and form scale.

The final determination would need to be made by doing both awater balance of your cooling system to determine how muchwater the boiler blowdown would be in relation to total make up,the water chemistry of the boiler blowdown and calculating the new make up waterchemistry for the tower based on the percentage of boiler water being used as make upversus the amount and chemistry of the make up water source. If the water chemistry of

a question go towww.cti.org

the mixed make up looks unfavorable theremay be ways to pretreat and filter the boilerblowdown water to make the boiler blowdownmore acceptable. This would require aneconomic analysis based on the pretreatmentcapital cost versus the savings seen in coolingtower make up.

Unfortunately sitting here in my office half wayaround the world from you it is hard to provideyou a definitive answer without know muchmore detail of water chemistry, the particularsof your system and the total economicsinvolved. If you are serious about doing thisI would suggest you consult a water treatmentspecialist in India who could provide moredetail to answer your question.

Question 3’m preparing a presentation for a group of NewYork City high school chemistry and physicsteachers on mathematical curves that haveimportant engineering applications. Do youknow, or can you suggest someone who mightknow, why power plant cooling towers areoften hyperboloid in shape? (Or are theycatenoids!?) Does the shape provide betterheat transfer, or does it produce a strongerstructure, or are there other reasons?

Reply to Question 3 -

Natural draft cooling towers are machineswhich permit a liquid, generally water, to becooled. The heat is removed from the liquidand transferred to the air. As the air passesover the warm liquid, it is cooled and the airbecomes warm and moist and leaves thecooling tower. The cooling process (heattransfer) is about 25% by conduction andabout 75% by latent heat transfer. The shapeof the cooling tower, hyperboloid, does notcontribute to the heat transfer process.

The hyperboloid design is strictly forstructural reasons. With such a design the shellwill be very strong and relatively thin. Forexample, at the throat (the smallest diameter)of the cooling tower, the thickness of the shelltypically can be 8 inches while the thicknessof the shell at the top and bottom can be 3-4feet.

A cooling tower is a heat rejection device, which extracts waste heat to theatmosphere though the cooling of a water stream to a lower temperature.Common applications for cooling towers are providing cooled water for air-conditioning, manufacturing and electric power generation. The genericterm “cooling tower” is used to describe both direct (open circuit) andindirect (closed circuit) heat rejection equipment. A direct, or open-circuitcooling tower is an enclosed structure with internal means to distribute thewarm water fed to it over a labyrinth-like packing or “fill.” The fill mayconsist of multiple, mainly vertical, wetted surfaces upon which a thin film ofwater spreads. An indirect, or closed circuit cooling tower involves no direct

contact of the air and the fluid, usually water or a glycol mixture, being cooled.In a counter-flow cooling tower air travels upward through the fill or tube bundles,

opposite to the downward motion of the water. In a cross-flow coolingtower air moves horizontally through the fill as the water moves downward.Cooling towers are also characterized by the means by which air is moved.Because evaporation consists of pure water, the concentration of dissolved

minerals and other solids in circulating water will tend to increase unlesssome means of dissolved-solids control, such as blow-down, is provided.

Some water is also lost by droplets being carried out with the exhaust air (drift).For more information visit the Cooling Technology Institute at www.cti.org.
