Synthesis of heat exchanger networks: II. Evolutionary generation of networks with various criteria of optimality

Abstract An evolutionary method is presented for the synthesis of heat exchanger networks. Starting from feasible solutions which preferably exhibit maximum energy recovery, The synthesis of such solutions has been discussed in Part I (see Linnhoff and Flower, 1978). the method allows systematic promotion of desired design features such as low overall cost, suitability for starting‐up procedures, observation of safety constraints, etc. Seven examples based on standard literature problems are used to illustrate the method.
