A computer code has been developed to calculate optimal distribution of streams flowing through a certain class of complex heat exchanger systems in order to achieve maximum heat recovery. This program can be integrated into an on-line computer program controlling any exchanger system of this class. An accurate and detailed heat exchanger model, based on Gilmour's design method, is used to calculate the exit temperatures of each exchanger. The optimal distribution of parallel streams within a group is found by the direct search method of Hooke and Jeeves, modified to include constraints, while the overall optimization of the system (composed of groups in series) is achieved via dynamic programming. The method is demonstrated for two real cases.
