This work addresses the problem of using seawater for cooling and the associated
environmental problems caused by the usage and discharge of biocides. The discharged
biocide and its byproducts are toxic to aquatic lives and must be decreased below certain
discharge limits on load prior to discharge. The conventional approach has been to add
biocide removal units as an end-of-pipe treatment. This work introduces an integrated
approach to reducing biocide discharge throughout a set of coordinated strategies for inplant
modifications and biocide removal. In particular, process integration tools are used
to reduce heating and cooling requirements through the synthesis of a heat-exchange
network. Heat integration among process of hot and cold streams is pursued to an
economic extent by reconciling cost reduction in utilities versus any additional capital
investment of the heat exchangers. Other strategies include maximization of the
temperature range for seawater through the process and optimization of biocide dosage.
This new approach has the advantage of providing cost savings while reducing the usage and discharge of biocides. A case study is used to illustrate the usefulness of this new
approach and the accompanying design techniques.
