06-06: Improving Localized Corrosion in a Complex Cooling Water System CorrosionA DuPont plant has experienced severe localized corrosion from a complex corrosion phenomenon in its cooling water system. A large semi closed cooling water system was created ten years ago and since has had aggressive corrosion attack particularly on carbon steel surfaces. A new treatment program has been applied and is currently providing improvement. The paper will present performance data on the treatment program and other steps that have been

An ongoing interdisciplinary research project is investigating the effects of wind on the thermal performance of ACCs with a field study of an existing full-scale combined cycle power plant

total bacteria counts

Water treatment programs that include a combination of oxidizing and non-oxidizing biocides provide a broad-based approach to microbial control to minimize the negative impact of biofouling

has been expanded and revised to provide a computerized means to predict the thermal performance and determine the associated energy requirements for specified tower design

Based on the results of the wet chemistry tests

Cooling towers are the equipment responsible for reducing the temperature of hot water from the process

You put your money on the table enough times and the casino takes 5

many design features must be considered to produce optimum performance

Significant reductions in mechanical properties were found and consistent relationships between awl penetration and mechanical properties were observed

Maintenance of Cooling Towers usually poses quite a number of occupational/personal safety challenges
