Abstract: Many methods have been proposed for synthesis of heat exchanger networks in recent years,
most of which consider single pass exchangers. In this study some evolutionary rules have
been proposed for synthesis of multipass exchanger networks. The method is based on the
heuristic that optimal networks should feature maximum energy recovery and have the minimum
number of shells. The effectiveness of the developed evolutionary rules is demonstrated
through some literature examples.
