AB - The revamping of pre-heat trains requires simultaneous consideration of heat recovery thermodynamics, heat exchanger technology, heat exchanger fouling, control strategy and future plant operation. Heat flow analysis allows the engineer to link plant structure and potential heat recovery. The temperature and pressure field plots then provide guidance on the fouling that is likely to occur within the individual heat exchangers. Thermal simulation coupled with fouling models can be used to examine how individual heat exchanger designs behave in a given pre-heat train structure. This allows the engineer to explore the true economics of a proposed revamp. The same simulator can be used to evaluate de-salter control options and to identify optimal exchanger cleaning strategies. Once, a plant has been revamped the simulator can be used to provide the operator with guidance on how fouling affects current plant performance and evaluate the consequences of removing exchangers for cleaning.
