02-15: Corrosion and Biofouling Control in a Refinery Cooling Water System MaterialsExperience has shown that corrosion and biofouling control are important factors in operating a "clean" open evaporative cooling water system. Treated sewage water as make up to the cooling tower requires novel approaches to control corrosion and biofouling besides meeting environmental regulations. An intensive field study was conducted to evaluate the effectiveness of a non chromate treatment program. On line cleaning of the exchangers occurred

The comparison between cooling towers’ audit in chemical

and significantly decrease the amount of blowdown water

and water can be conserved if energy usage is allowed to increase

Some case histories are also discussed

thermal operating level of the tower relative to the original design conditions

The visible plume from these towers was obstructing the vision of pilots on the taxiway

Ohio in 2011

The helper towers are now in commercial operation and recent field drift testing has validated the results of the R&D program

This index could be utilized to set relative values on water and energy usage for codes or for guidance in "green" applications

Typical indicators of wind effects are increases in steam back pressure
