1. Slide 1: 63rd Annual International Water Conference

   63 Annual rd International Water Conference Pittsburgh, Pennsylvania October 23, 2002

2. Slide 2: Chemical Cleaning of Industrial Utility Systems

   Chemical Cleaning of Industrial Utility Systems James E. Farmerie HERC Products, Inc Wexford, PA

3. Slide 3: Issues Affecting Water Treatment Chemical Performance

   Issues Affecting Water Treatment Chemical Performance “ System Parameters “ Make-up Water Quality “ Feed Equipment “ Monitoring Equipment “ Operator Attention “ Proper Chemistry

4. Slide 4: Deposits

   Deposits “ Corrosion By-Products “ Mineral Precipitants “ Silts & Clays “ Biological

5. Slide 5: Problems

   Problems “ Inefficiencies in heating/cooling “ Poor heat transfer surfaces “ Health Related “ Decision - Shut down (Production concerns) - Wait for scheduled down time

6. Slide 6: Cleaning Opportunities

   Cleaning Opportunities “ Pre-operations “ Disinfection “ Hard/Soft Scale Removal

7. Slide 7: Pre-operation

   Pre-operation “ Systems used seasonally - Accumulate in Exchangers, Fill, Basin - Start-up/Shut down “ Expansion of Equipment/New Construction - Oil & Grease - Loose Debris - Silt & Clays

8. Slide 8: Disinfection

   Disinfection “ Growth interferes with heat transfer “ Growth under deposits where routine biocide usage is not effective “ Legionella “ Biofilm

9. Slide 9: Deposits

   Deposits “ Metal Oxides from corrosion products “ Mineral Precipitants “ Soft Silt & Clays

10. Slide 10: Off-Line Chemical Cleaning

    Off-Line Chemical Cleaning “ Equipment “ Chemistry “ Technology

11. Slide 11: Cleaning Process

    Cleaning Process “ Analyze deposit “ Formulate Cleaning Solution - Penetrate, Disperse, & Dissolve Deposits - Acid, Wetting Agent, Surfactant, Inhibitor “ Circulate Cleaning Solution “ Determine Recirculation Required

12. Slide 12: Desired Cleaning Solution

    Desired Cleaning Solution “ Rapidly loosen tuberculation, hard/soft scale, encrustation, & biological growth “ Dissolve the deposits “ Little affect on metal surface “ No affect on gaskets/seals “ Environmentally safe “ Spent solution easily disposed

13. Slide 13: Calcium Carbonate example

    Calcium Carbonate example “ Using Muriatic acid + components CaCO3 + 2 HCL = CaCL2 + CO2 + H2O “ Neutralize excess HCL with Caustic HCl + NaOH = NaCl + H20

14. Slide 14: Differentiate Chemical Cleaners

    Differentiate Chemical Cleaners “ Acid + Component Product “ Correct Acid for deposit “ Recirculation Equipment “ Monitoring cleaning process “ Know when to stop

15. Slide 15: Salt River Project Kyrene Generating Plant Tempe, AZ

    Salt River Project Kyrene Generating Plant Tempe, AZ “ Peak Demand Plant “ Two Steam co-generation plants “ Gas or Oil Fired “ Total of 250 Mega Watts of Power

16. Slide 16: Salt River Project Example

    Salt River Project Example “ Mild Steel, Admiralty Brass, various grades of Stainless Steel, Copper Nickel Metallurgy “ Make-up of well water, city water, or DI water “ Calcium carbonate, Complex iron oxides, silica, lead, and chromium tuberculation “ Cooling Water Tank “ Cooling Water Heat Exchange

17. Slide 17: Salt River Project Example

    Salt River Project Example “ Isolated each heat exchanger loop into two 6,000 gallon closed-loop sections “ Conducted Hazard and Procedure review “ Drained the system “ Disconnected the pumps and piping spools

18. Slide 18: Salt River Project Example

    Salt River Project Example “ Connected hoses from the Mobile Recirculating Unit to the cooling water pumps and cooling water tank “ Circulated Cleaning Solution throughout each of the systems for 30 hours

19. Slide 19: Salt River Project Example

    Salt River Project Example “ Monitored Cleaning process to determine endpoint of the procedure “ Neutralized the spent solution for disposal “ Cooling tank and heat exchanger were cleaned and free of scale

20. Slide 20: Salt River Project Benefits

    Salt River Project Benefits “ Clean system to initiate treatment program “ Correct inadequate treatment procedures “ Allows plant personnel to implement program to decrease blowdown, increase cycles, lower energy cost, lower water & waste cost (LOWER TOTAL COST)
