8:30a - 9:00aTP07-02 - Design and Operation of a Counterflow Fill and Nozzle Test Cell: Challenges andSolutionsJean-Pierre R. Libert - EvapTech, Inc.

In his current position of Technical Director with EvapTech Inc., Jean-Pierre plans,directs and controls the technical matters involving thermal ratings and optimizations,mechanical equipment selections, hydraulic calculations (particularly in the case of plume-abated cooling towers), acoustics, water chemistry, thermodynamic R&D and relatedproduct development activities.

Jean-Pierre holds a MS Degree in Mechanical Engineering from Faculté Polytechnique de Mons,Belgium, and has been an active Member of the Cooling Technology Institute (CTI) since 1985. Heis a Member in good standing of the American Society of Mechanical Engineers (A.S.M.E.).Jean-Pierre has extensive cooling tower industry experience acquired since 1979 in a variety ofassignments in Belgium, Mexico and the U.S.A.

While factory-assembled cooling towers are compact enough to be tested and certified inenvironmental test chambers, field-erected towers can only be tested on-site once built. In order torate them beforehand, their components must be tested individually in test cells designed to thateffect. The size of the test cells, their configuration, operation and the instrumentation used tocapture the fundamental thermodynamic data require money, time and good engineering skills to beable to acquire meaningful and useful data.

9:00a - 9:30aTP07-04 - Effects of Wind on Air-Cooled Condenser PerformanceJohn S. Maulbetsch, Maulbetsch Consulting and Michael N.

Leandro Etcheverry, Ph.D.., P.E., Structural Preservation Systems. A member of ACI,NACE and ICRI, Etcheverry specializes in the diagnostic evaluation and rehabilitationof corrosion-induced deterioration in concrete structures. He received a Ph.D. degreein civil engineering from The University of Texas at Austin. He also holds a BS (CivilEngineering), BA (Economics) and Master of Engineering (Civil Engineering) all from

Cornell University, Ithaca, New York. He is a NACE certified Cathodic Protection.Since an environmental conductive to corrosion-induced deterioration exists in natural drafthyperbolic cooling towers, understanding of the deterioration mechanisms as well as effectiverehabiliation strategies are required to preserve the value of natural draft hyperbolic cooling towers.Due to the progressive nature of corrosion deterioration, the consequences and costs associatedwith delaying repairs can be signifcant. By utilizing state-of-the-art concrete repair technologyaugmented with high performance construction materials and protection systems, cost effectiverepair programs can be implemented. These repair programs can extend service life and protect thevalue of the high initial investment associated with the contstruction of hyperbolic natural draftcooling towers.

This paper willfocus on the International Building Code as pertains to factory assembled evaporative coolingequipment and emphasize the methodology for determining the applicability of the code to specificprojects.

11:00a - 11:30aTP07-12 - Sound Measurement from Field Erected Cooling TowersKen Hennon and David Wheeler, Clean Air Engineering

The CTI Test Code for Measurement of Sound from Water Cooling Towers, ATC-128(2005), defines two types of sound emissions tests for large cooling towers. Theobjective of the first test method is to quantify the sound level or personnel exposurelevels in the working environment of the cooling tower. The objective of the second testmethod is intended to measure the total sound power emitted by the cooling tower by

near field measurements. These near field measurements can then be subsequently projected tocalculate sound power at far field points. This paper addresses both types of tests and present datafrom a recent field test and explains the challenges associated with the successful execution of a fieldtest program.11:30p - 12:00pTP07-14 - Smart Vibration SwitchesDr. George Zusman - PCB PiezotronicsDr. George Zusman serves as a Director of Product Development at PCB Piezotronics IMI-sensordivision.

He is a memberof the Cooling Technology Institute (CTI), and active on the water treatment committee of the CTI.Control of water treatment chemistry utilizing instrument measurement of system water flow andcycles of concentration provides precise control of chemical additives. The chemical testingperformed then becomes a check on the control, rather than a primary control output. On-linechemical analysis is not needed. Statistical analysis of data proves the control capability isexcellent. Opportunities exist to utilize existing instrumentation in some cases along with newmeasurements to synthesize systems that are effective, economical and fully connected withtoday’s information technology.

10:00a - 10:30aTP07-07 - Zero Blowdown for Cooling TowersSam Owens, CHEMCO International, Inc.

10:30a - 11:00aTP07-09 - Twenty-Years of Cooling Water Treatment Experience in ManhattanDr. Marcus N. Allhands, PE and Carmine Puglisi, Orival, Inc.

Marcus graduated from Purdue University with a BS in agricultural engineering majoringin soil and water. After twelve years of industrial product development engineering heentered the University of Florida where he earned his PhD in agricultural engineeringmajoring in soil & water with minors in environmental engineering and hydrogeology.He is a registered professional engineer in the states of Illinois and Florida. Marcusspent seven years as Water Quality Manager of a design engineering firm in southwest

Florida and then ten years with Amiad Filtration Systems as Senior Application Engineer. Marcusis now Vice President of Orival, Inc., a broad spectrum filtration company.Twenty years ago, Hartz Mountain was concerned about water quality issues on their new HVACsystem. Pollen, dust and insects would surely be scrubbed from the atmosphere by the large rooftop cooling tower that was to provide cooling water to a package unit designed to condense waterfrom a nearby commercial building to condition indoor air. The protection provided by the originalsolution and minimal maintenance are what convinced management to replace the initial installationwith a similar product fifteen years later. This paper will describe the original treatment system,maintenance issues over the past twenty years and chemical cost savings.

11:00a - 11:30aTP07-11 - Water Saving Designs for Power Plant Heat SinksHector Cruz, Bechtel Power Corporation

This paper recommends economical water-saving methods for the design of heat sinksystems for a theoretical 750 MW power plant located in either an arid region or in anarea where there is low water availability. The basis keeps the same turbine cycle sizeas a base plant but lets the plant output float. The base design represents a standardcooling tower that would normally be provided for a power plant of comparable sizewithout special circumstances (or weather). The following water savings methods are

evaluated against a base case of 100 percent counterflow cooling towers and are compared to astandard wet cooling tower with single-speed fans. Water savings comparisons are based on annualaverage conditions and performance.

He holds professional registrations in 13 states and is an active member of the InternationalConcrete Repair Institute, American Concrete Institute, American Society of Civil Engineers, andStructural Engineers Association of Illinois.Two concrete cooling towers serving a generating station exhibited concrete deterioration, steelcorrosion, and water leakage. These towers needed major repairs that could be done only duringscheduled outages.Detailed structural analysis helped determine the maximum size, relative location, and sequencingof repair areas to ensure stability during repairs. Materials were chosen to withstand conditionswithin the towers.Structural engineers and construction material consultants took part in condition evaluation, repairdesign and construction quality assurance. Repair crews removed deteriorated concrete and usedspecialty shotcrete materials for structural restoration. Durability enhancements included awaterproofing coating on the interior. They sealed tower surfaces and sealed cracks with epoxy.Meticulous QC testing and inspection helped ensure the project’s success. After more than 15years of continuous service, the repaired towers show no evidence of on-going deterioration orstructural distress.

The coating technology provides thedesired release rate of the active ingredients in the table core, eliminating the need for mechanicalpumping systems. This chemical treatment method results in consistent chemical release, eliminationof electrical feed system components, improved program safety for operators, elimination ofchemical container disposal issues and is environment all safe.8:00a - 8:30aTP07-17 - Anionic Compatible Quat?Philip Sweeny, LONZA, Inc.

Philip Sweeny received his doctorate in Organic Chemistry from the University ofNorth Dakota in 1985. He has obtained 16 years or water treatment experience with aconcentration in the development and application of microbiological control programsfor cooling water, papermaking and recreational pool and spa applications. He holdsseveral patents in the field of water treatment and has presented papers at NACE,

TAPPI, AWT and ACS. He enjoys gardening and fishing in his spare time.Sunlight exposed cooling towers can develop significant algae-related fouling problems. The presenceof these algal mats or stringers clearly show that the cooling water program is out of control. Inaddition this fouling will often block the tower fill causing reduced efficacy.The use of oxidizing for algae control is fairly ineffective when used at normally encountereddosages. Most general purpose biocide are really designed for bacterial slime control rather thanalgae. Thus the use of supplemental algaecides is often required.

8:30a - 9:00aTP07-19 - Efficient One Step Phosphorous and Suspended Solids Removal from MunicipalWastewaterBen Gould, Ashbrook Simon-Hartley and Clarence Melancon, Water Filtration Technologies

Experienced in a wide range of treatment technologies including ultrafiltration & reverseosmosis membranes, ion exchange, carbon, media filtration and biological wastewatertreatment. Responsibilities have included process design, operation & maintenance,technical support and sales & marketing management in the industrial and municipalwater and wastewater markets. Current position is the Marketing Manager for the

Process Systems Group of Ashbrook Simon-Hartley in Houston, Texas.Reuse of municipal wastewater for cooling tower makeup is increasing in popularity, as it can meetmultiple requirements imposed by environmental, regulatory, political and economic factors. Theability to efficiently and economically remove suspended solids and nutrients in a single step isrealized by using a gravity driven, downflow, continuous operation, graded media filter. Suspendedsolids and phosphorous removal at levels greater than 90% is achieved, with effective particlefiltration to five microns. Using no moving parts, the filter operational reliability is high and theoperation and maintenance costs are extremely low.

holds 24 U.S. patents and has authored or co-authored more than 50 presentations and publications.He is a member of the American Chemical Society and frequently serves on various water treatmentcommittees and subcommittees associated with AWT, NACE, and CTI.Liquid biocides continue to be a popular choice for control of microorganisms in industrial watersystems and numerous treatment options exist in both oxidizing and non-oxidizing biocide categories.The purpose of this paper is to introduce a family of liquid biocides based on bromine chloride asthe active ingredient. These products were developed with the requirements of specific watertreatment segments in mind.Products are available for both the commercial and middle-market segments that deliver theconvenience and consistent activity that is much valued in these market segments. Higher activityproducts were also developed for large-volume heavy-industrial applications that feature activityapproaching that of fresh “off-the-line” bleach while still delivering the benefits of a stabilizedbromine system. This paper will point out the unique features of this family of products and showcomparative field and laboratory data to aid in proper biocide selection.

What is aCooling Tower?

A cooling tower is a heat rejection device, whichextracts waste heat to the atmosphere thoughthe cooling of a water stream to a lowertemperature. Common applications for coolingtowers are providing cooled water for air-conditioning, manufacturing and electric powergeneration. The generic term “cooling tower”is used to describe both direct (open circuit) andindirect (closed circuit) heat rejection equipment.A direct, or open-circuit cooling tower is anenclosed structure with internal means todistribute the warm water fed to it over alabyrinth-like packing or “fill.” The fill mayconsist of multiple, mainly vertical, wettedsurfaces upon which a thin film of water spreads.An indirect, or closed circuit cooling towerinvolves no direct contact of the air and the fluid,usually water or a glycol mixture, being cooled.In a counter-flow cooling tower air travelsupward through the fill or tube bundles, oppositeto the downward motion of the water. In a cross-flow cooling tower air moves horizontallythrough the fill as the water moves downward.Cooling towers are also characterized by themeans by which air is moved. Becauseevaporation consists of pure water, theconcentration of dissolved minerals and othersolids in circulating water will tend to increaseunless some means of dissolved-solids control,such as blow-down, is provided. Some water isalso lost by droplets being carried out with theexhaust air (drift).For more information visit the CoolingTechnology Institute at www.cti.org.

Water Reuse2007 Panel Discussion

Monday, February 5, 20072:00p - 3:45p

Phil Kiser and his group of panelist have lined up a terrific PanelDiscussion for you to participate in. The utilization of recycled/reuse water is a growing trend in water sourcing. Many parts ofthe US have water resource limitations based on drought,population growth and/or supply limitations. Industrial andmunicipalapplications of water facean increasingly challengingsupply,quality, and quantity issues.Many parts of the Gulf Coast

face limited water supplies even in normal conditions.Corpus Christi and other parts of the Gulf Coasthave a very limited industrial water supply. Waterresources in the region have been severely impactedby drought conditions. The Cooling TechnologyInstitute (CTI) has assembled a panel of industrialleaders to present and discuss water reuse issues.Panelists include Water Service, Manufacturing,Engineering, and Regulatory Professionalspresenting insight into water resourceimplementation and utilization. Many corporationsand operators are now facing mandatory reuseimplementation or will face both short term and longrange strategic planning for utilizing reuse.

The Panelist will review:• Technical aspects of water reuse issues• Manufacturing aspect of the use of

alternate water supplies.• Regulatory aspects of water reuse

including consumptive use andalternate supply

• Engineering and supply resourcedevelopment

The following questions were sent throughoutwebsite to the “Ask The Expert” Committee. This isjust a sampling of the types of questions we get fromthose of every walks of life. Thanks to the committeethe CTI is able to reach out in another way to helpthose in the industry and those who have interest inour Industry.

Question 1Can CTI provide any reference/typi-cal drift values for industrial cool-ing towers? I found some driftvalues online in EPA’s AP-42document but am hoping to find other representativedata.

Reply to Question 1The paper “Cooling Tower Emissions QuantificationUsing the CTI Test Code ATC-140 (TP03-08), pro-vides survey of drift rates for different cooling tow-ers tested over a twenty-five year period. As pointedout in the paper, the drift rates, even for cooling tow-ers with similar drift eliminator technologies, are highlyvariable. The actual drift rate is highly dependent onthe quality of the installation and the condition of thedrift eliminators and water distribution system. Thatsaid, the drift rate quoted by EPA AP-42 is highlyconservative. A cooling tower with drift rate as highas that quoted by AP-42 would have drift eliminatorsin very poor condition. Manufacturers are currentlyquoting drift rates of 0.0005 per cent of the circulatingwater flow. To achieve this level of drift control, theinstallation of the drift eliminators, must be perfectand there can be no problems with the hydraulicswithin the tower. A number of older technology drifteliminators actually performed better than much newertechnologies because the installation of the older drifteliminators was more uniform.

Question 2I am studying the feasibility ofusing closed type cooling towerto replace the existing opentype. The following issues areof concern:• Is there another modification of existing water pumpor if the pressure drop of closed type coil is lowerthan the static head of open cooling tower will therebe problems?

• Is the pressurization make up unit required?

• Can the open type and closed type cooling towers operate in parallel at the same system?

Reply to Question 2In reply to your questions:

• You can replace an open circuit (assuming you are using a cooling tower) with a closedcircuit (air cooler).• The typical pressure drop in a closed circuit air cooler is 10 to 15 psi. If you replace theopen circuit with a closed circuit air cooler you most likely will not need to change theexisting pump(s), but be certain to design the air cooler to match the pressure drop/headavailable in the existing open circuit. Just be sure to tell the Air Cooler manufacturer what

pressure drop you want in the air cooler.• The air cooler manufacturer can provide anatmospheric expansion tank for make-up wa-ter.

• You can operate the oen type and closed typesystem at the same time in parallel. A goodway to conserve water. Just use the open cir-cuit on the hottest ambient days.

Question 3I am reviewing the effects of a “hydrogeneconomy.” The question arises as to the fateof the waste heat derived from various power-plant technologies. As partof this review, I amtrying to estimate,roughly, how muchwater islost to theatmosphere fromcooling towers, measured, say, in gallons ofwater per kWh. I am doing this analysis forCCNG, coal, and nuclear plants. I need a “ruleof thumb” for these losses rather than a de-tailed engineering anlysis.

Reply to Question 3The calculation of the make-up to cooling towerhas 3 parts:Evaporation - Recirculation Rate x Evapora-tion Rate is about .8% May through Octroberand 0.6% November through April in southernstates where wet bulbs approach 80oF. A tonof refrigeration requires 14,000btu/hr of heatremoval (includes inefficiency of coolingtower). Definition of a BTU is the amount ofheat to raise 1# of water 1oF. If we assume 10oFdelta temperature, we get 14,000* 1/10 = 1400#/hr recirculation rate to remove the 1 ton of heat.1400#/hr is equal to 2.8 gpm / 10oF rise in tem-perature. Evaporation loss = 2.8* .008 = 0.0224gpm/ton for summer and 0.0168 gpm for winterconditions.Drift is amount of water droplets that escapesfrom top of cooling tower. The water loss isdependent on efficiency of drift eliminators.Drift eliminators range from 0.002% to 0.0005%.I would use the 0.00002 x Recirculation Ratefor estimation purposes. Per ton, 2.8 gpm*.00002 = 0.000056 (this is insignificant for smallcooling towers but for large utility and indus-trial cooling towers it is significant).Blowdown is amount of water that is purgedfrom the cooling tower to control cycles of con-centration to prevent fouling and scaling. Allcooling towers require blowdown no matterwhat source of water or treatment program.The optimal cycles of concentration whenmake-up water and blowdown disposal costsare not a huge consideration is between 5-7cycles of concentration. Cycle of concentration is measured by taking one of the chemicalconstituents in tower water and divide it by the same constituent in make-up water. Chlo-rides are commonly used as the constituent.Blowdown = Evaporation Rate / (C-1) for this example: B = 0.0224 / (5-1) or 0.0056.Make-up = Evaporation + Drift+Blowdown = 0.0224+0.000056+0.0056=0.028056 gpm perton or 1% of recirculation rate for a 10oF delta temperature at 5 cycles of concentration insummer.

The analysis you are looking for should be about the same. The 1% rule of thumb is prettygood approximation. The equations above can easily be adaped for heat rejection forcondenser cooling.

have such speakers as Ralph Wyndrum, III PEAK P.E. with SPX Cooling Technologyspeaking on “Air-Cooled Condenser Technology (Design Fundamentals)”; Tom Ritterwith EnVibe, Inc. speaking on “Tower Fan Vibration Analysis”; Richard Altice withStrongwell speaking on “FRP Structural Components Wood Versus Fiberglas”; and JimCuchens P.E. with Southern Company speaking on “Air-Cooled Condenser DesignPractices.”The Panel Discussion on Monday, 2:00p – 3:45p will be on Water Reuse. The utilization ofrecycled/reuse water is a growing trend in water sourcing. Many parts of the US havewater resource limitations based on drought, population growth and/or supply limitations.Industrial and municipal applications of water face an increasingly challenging supply,quality, and quantity issues. Many parts of the Gulf Coast face limited water supplies evenin normal conditions. Corpus Christi and other parts of the Gulf Coast have a very limitedindustrial water supply. Water resources in the region have been severely impacted bydrought conditions. The Cooling Technology Institute (CTI) has assembled a panel ofindustrial leaders to present and discuss water reuse issues. Panelists include WaterService, Manufacturing, Engineering, and Regulatory Professionals presenting insightinto water resource implementation and utilization. Many corporations and operators arenow facing mandatory reuse implementation or will face both short term and long rangestrategic planning for utilizing reuse. Operators, owners, and engineersIf you don’t attend any other cooling tower related meeting or conference this year, youdon’t want to miss this. The CTI program committee has put together a program that willoffer the best opportunity to inform, educate and expand your knowledge about thisindustry. We hope you come prepared to take full advantage of everything we have tooffer you. A great location, outstanding food and entertainment and a conference that willgive back to the membership what you want “Information “I, Glenn Rees, Paul Nelissen, Bill Immell and Gary Geiger, Brandon Rees and John Zibrida,your program committee, invite and welcome you to the 2007 winter conference andmeeting.See you on the Beach in Corpus Christi, Texas.
