Abstract: The work deals with recent developments in heat exchanger networks (HENs) targeting. The following issues were addressed: minimum utility cost calculation by generalized transshipment model for nonpoint utilities; targeting approach for minimum area of counter-current (1-1) and multipass (1-2) heat exchangers; and minimization of number of matches at targeting stage by generation of near-balanced subsets of streams. These problems have been solved using novel optimization models. A description of the methods and some examples of applications are given.
