ST100 Series Flare Gas Flow Meters

FCI Exclusive Split-range, Dual Calibration – SR2x™ (Environmental Agency and Emissions Trading Compliance)Many oil & gas operations, refineries and chemical plants have flare applications uniquely challenged with two diverse flow conditions, very low flow under normal conditions and very high flow during an upset/blowdown condition. These industries are then further challenged to comply with environmental agencies and emissions trading regulations for their flares stipulating flow meter accuracy of ± 5% of reading throughout the entire measuring range. FCI answers this challenge with our exclusive SR2x split-range/dual calibration option in the ST100 Series which provides:

Split ranges: Two separate and discrete ranges, one optimized in the low flow range and one optimized in the high flow range

Double calibration points strategically placed and optimized in the low flow range and high flow range to achieve ± 0.75% reading, ± 0.5% of full scale to a maximum of ± 5% of reading

Dual 4-20mA analog outputs: One dedicated to the low flow range and the other to high flow range; this ensures maximum resolution of both the low flow and high flow range at the DCS, or, if any of the bus communications are specified, a single, contiguous high accuracy digital value over the entire flow range is sent to the DCS

When your flare application is characterized by this difficult low flow/high flow situation, FCI’s ST100 Series will provide a regulatory compliant, exclusive thermal dispersion flow meter solution.

VeriCal ™ In-Situ Calibration Verification Many flare meter installations, either per plant edict or for compliance with environmental regulations, require regular validation of calibration. Traditionally this has required a cumbersome and costly project to remove the meter from service and return it to a lab, which is particularly frustrating if the meter is found to still be within calibrated specifications. FCI’s exclusive VeriCal option eliminates the need for unnecessary de-installation. The VeriCal system provides

a simple-to-use tool to verify the FCI flow meter is still within calibration without extracting the meter from pipe. The VeriCal system consists of a special VeriCal ready flow sensor, a portable VeriCal kit (which can be used with any number of VeriCal-ready ST100 flow meters) and an additional benchmark calibration document to which field verification samples are compared. For more detailed information on VeriCal, please refer to FCI ST100 Series brochure.

Dual-Element Systems In pipe sizes larger than 16 inches [406 mm] a dual-element averaging system may provide better measurement performance and a more viable solution when it is impractical or impossible to provide the required straight-run or installation of a flow conditioner is difficult. ST100 Series models ST102A, ST112A, STP102A, and STP112A are dual-element averaging systems.

To determine if your flare meter application will benefit from using a dual-element averaging design, submit an FCI application data sheet or use AVAL, FCI’s online flow meter sizing tool.

Communicate the Flow Local readout, multiple 4-20 mA analog outputs, digital bus communications including HART, Foundation ™ fieldbus, Modbus and more, are all available with ST100 Series to provide the flare flow data to you and your systems. There is simply no other flare meter with the comprehensive selection of interfaces as ST100 Series. And, should you ever want to change or upgrade, ST100 is field upgradeable to any of the available outputs.

“ FCI flow meters have been providing accurate and easy-to-obtain venting data at our offshore facilities.”

– M. Skaer, Facilities Engineer ANKOR Energy LLC

Key Criteria For Flare Flow Meter Selection

– Meet local environmental agency requirements for accuracy and periodic calibration verification

– Wide turndown for both low flow and high flow conditions

– Certified calibration for mixed hydrocarbon flare gases

– Multiple calibrations for variations in composition

– Direct mass flow measurement

– easy to install, minimal penetration points

– Non-clogging, non-fouling, no moving parts design for lowest maintenance

– Agency approved for installation in explosive gas classified environments

– Stainless steel wetted parts and optional stainless steel process connections and enclosure housings

Flare gas applications present several unique challenges to plant, process and instrument engineers when selecting a flow meter solution. These can include many or even all of the following:

� Both low and high flow conditions – low flow sensitivity is critical to capture leaking relief valves and sensing air leaking into system, and very high flows occur during upset conditions

� Mixed gases – flow meter calibration specifically for hydrocarbon composition gases and matched to actual process conditions

� Large pipe sizes – as line sizes increase effective and suitable flow metering technologies decrease

� Lack of available straight-run – larger line size and limited real estate, particularly on off-shore platforms, are restrictive to providing required straight-run to achieve repeatable flow metering accuracy

� Compliance with local environmental regulations – meet performance and calibration procedures mandated within local regulations such as US ePA’s 10 CFR 40; 40 CFR 98; eU Directives 2003/87/eC and 2007/589/eC; US MMR 30 CFR Part 250, Subpart k, Section 250 and others

� Limited access – Pipe access and reaccess for installation, maintenance or servicing is difficult; spool-piece flow meters may require prolonged process shut-down and extensive on-site labor costs to install

� Agency approvals for installation in hazardous (Ex) locations – The entire flow metering instrument should carry agency approval credentials for installation in environments with potential hazardous gases; enclosure only ratings are inadequate (and risky)

� Offshore platforms corrosive salt water – offshore platform may require use of stainless steel on all exposed instrument materials, including sensors, process connections and enclosures

Flare gas mass flow measurement

In a variety of oil production and refining environments, FCI’s GF90Series mass flow meters monitor total gas flow to flare stacks aswell as through feed lines to the main flare header. As an integralpart of energy conservation and emission control systems, it meetsstrict accuracy and wide turndown requirements. The GF90 is highlyreliable because of its durable construction and no moving partsdesign. Units are also used to assist in the control of steam additionand blower and louver adjustment for smokeless flares. A packinggland option permits hot-tap installation and retraction of the flowelement without system shut down. The GF90 also features high flowrange turndown ratios up to 1000:1 and micro-processor based user-friendly electronics.

Tanker loading /unloading

GF90 Series mass flow meters provide the solutions for several difficulttanker loading/unloading applications. It is used to measure the flowof hydrocarbon vapors that are vented from the storage tanks, bothon the tanker and at the port tank farm, to ensure compliance withenvironmental laws governing waste vapors. It is also used to measurenitrogen gas flow to inerting and gas blanketing systems that areoften required in these operations. Finally, FCI’s GF90 may be usedto measure flows to flare systems to assist in determining “throughput loss” for the tank farm.

Chemical injection /additive flow monitoring

In monitoring chemical and other additive injection flow, the ultra-sensitive FLT93L inline FlexSwitch® outperforms the competition. Itdetects gas flows down to 0.6 cc/sec and liquid flows down to0.02 cc/sec -- ideal for virtually all injection processes. The no-moving-parts flow element design provides outstanding durabilityand reliability under the harshest process conditions. And, the inherentthermal time delay, available in all FCI flow switch/monitors, preventsfalse alarms caused by flow pulsation and eliminates the need forauxiliary time delay relays. Optional dual switch point circuitry helpsmaintain product quality and process safety by alarming both highflow and low flow conditions.

Automated oil well testing systems

FCI FLT93S FlexSwitch Series have continued to play a key role inthe automation of oil well testing facilities throughout the UnitedStates. Thousands of units are in service today, monitoring the flowof crude oil from the well, so that non-producing sites can bequickly identified and corrected. In addition to improving productivity,this efficient no-flow detection system eliminates time wasted onthe continued testing of non-producing wells. These ruggedFlexSwitch monitors enable the system to automatically switch to thenext well in the test cycle.

Pump-off control

FCI’s FLT93S FlexSwitch Series is well suited to monitor productionin oil wells and indicate when an extended pump-off conditionoccurs. Coupled with a programmable logic controller, the FLT93Scan control the operation of the well to optimize oil production;while minimizing wear and tear on the down hole pump. In addition,restricting the operation of the pump to periods when oil is producedsaves energy and reduces operating costs.

Reverse flow switching

Nitrogen is utilized for purging and blanketing throughout a chemicalplant /refinery. The possibility of contaminating the nitrogen supplywith hydrocarbon gas exists if the pressure at the destination becomesgreater than the pressure at the source. The FCI RF83 bi-directionalflow monitor is used to shut down the supply line if flow is detectedreturning back to the supply tank.

Interface control in separation vessels

Unlike density-dependent displacers, often used for level and interfacecontrol, the FLT93S FlexSwitch Series relies on the specific heat transferproperties of the media involved to identify product interface. Becauseof this unique detection feature, interfaces between products of similardensity are reliably controlled in separating tanks and other vessels.FCI liquid level and interface controllers can identify the interfacebetween any media including liquids, slurries, foams and evenemulsion layers. The dual switch point option allows one instrumentto control two different product interfaces. Two or more units areused to control product discharge and intake at specified points.

CI introduced the first thermalflow switch /monitor in 1964and has since established a

worldwide reputation for the design andproduction of precision high performanceflow, level and temperature instrumentation.With reliability second to none, FCI hasplaced over 200,000 units in the fieldcovering the full range of liquid, gas andslurry process requirements. FCI productsservice some of the world's most demandingprocesses in industries such as food &beverage, pharmaceutical, chemical, oiland gas, pulp and paper, power and energy,water and wastewater, nuclear power,aerospace and more. FCI offers a broadrange of instrumentation solutions andservices, from off-the-shelf devices to customengineered systems. FCI's engineeringstaff provides expertise in mechanical,electronic and thermo-dynamic disciplinesoffering innovative solutions to specializedcustomer application needs, configurationobjectives, software enhancements, andmaterial problems.

Thermal Dispersion principleThe typical sensing element contains twothermowell-protected precision platinumResistance Temperature Detectors (RTDs).When placed in the process stream, oneRTD is heated and the other RTD senses theprocess temperature. The temperaturedifference between the two RTDs is relatedto the process flow rate as well as the

properties of the process media. Higherflow rates or denser media cause increasedcooling of the heated RTD and a reductionin the RTD temperature difference.

FlexSwitch® FLT93 SeriesThe FLT93 Series utilizes proprietary thermaldispersion technology to provide the highestreliability in flow, level and temperaturedetection. The sensing element is composedof two matched RTD's. One RTD is prefer-entially heated. The other RTD is unheatedand thermally isolated to provide continuousprocess condition temperature and baselineindication. At no flow or under dry condi-tions, the temperature differential betweenthe two RTDs is greatest.

For flow / no flow detectionNo-flow conditions produce a large signal.As flow increases, the heated RTD iscooled and proportionally reduces thetemperature differential. Changes in flowvelocity directly affect this rate of heatdissipation. An electronic circuit normalizesthe differential measurement with theprocess media temperature and converts

the RTD temperature/resistance differentialinto a DC voltage signal. This signal isprovided at output terminals and used todrive two adjustable setpoint alarm circuitsthat are independently field configurablefor specific flow service applications.

For liquid level /interface detection Dry conditions (no liquids present) producethe greatest temperature differential. Thesignal decreases when the level element issubmerged as the cooling effects of thefluid drive the temperature /resistancedifferential downward. Since all processfluids have different thermo physicalproperties, different fluids exhibit uniqueheat transfer characteristics. Interfacedetection between non-miscible fluids canbe factory or field calibrated to alarmwhen the fluid changes from liquid tofoam, between two different fluids, orbetween fluid and rag layer or emulsion.
