COPs put the heat on cooling towers
Article Abstract:
Government and industry officials are considering the development and implementation of a code of practice to control water-borne bacteria, particularly Legionella pneumophila, in cooling towers. Although industry associations have opposed such regulation, the Cooling Tower Institute and the American Society of Heating, Refrigeration and Air-Conditioning Engineers have stepped up to promote voluntary guidelines. Such guidelines will move cooling tower manufacturers to conduct research and development to update technology, particularly for water treatment systems that contain bacterial growth.

Design basics for cooling systems
Article Abstract:
The cooling system design of chemical-process plant influences the operation and the sizing of heat exchanges in the process units. Improper design could result in overall inefficiency, plant shutdowns or other problems such as premature corrosion, scaling and biological fouling. The design and material requirements of the three types of water-based coolinbg systems: once-through, open recirculating and colsed recirculating, are discussed.

Reduce the plume from cooling towers
Article Abstract:
The installation of reduced-plume cooling towers (RPCTs) in new industrial projects reduce the visual problems associated with the condensing water vapor. An innovative technology that employs a polyvinyl heat exchanger and air dampers is described. The system offers several advantages over metal fin-tubes used in older towers, such as less corrosion, less fouling, less water, less weight and less cost.
