88-07: Replacement of Chlorine Gas at a Major Gulf Coast Refinery With a New LegionellaAbstract: A safe, cost effective biocide replacement for chlorine gas has long been sought. Described are results from a product evaluation that led to the replacement of chlorine gas in 25 cooling towers. The product selected is a new; EPA registered biocide and is a bromine and chlorine derivative of methylethyl and dimethylhydantoin. Performance tests have shown that effective bio control is achieved when the product is applied on a slug basis. A

and the establishment of protective measures allowed for successful reuse of this stream at minimal risk

An often-neglected area of cooling water treatment is microbiological control

These possibilities are discussed with illustrative pictures and data presented
