Abstract
Synthesis of heat exchanger networks (HENs) is inherently a mixed integer andnonlinear programming (MINLP) problem. Solving such problems leads to difficultiesin the optimization of continuous and binary variables. This paper presents a newefficient and robust method in which structural parameters are optimized by geneticalgorithm (G.A.) and continuous variables are handled due to a modified objectivefunction for maximum energy recovery (MER). Node representation is used foraddressing the exchangers and networks are considered as a sequence of genes. Eachgene consists of nodes for generating different structures within a network. Resultsshow that this method may find new or near optimal solutions with a less than 2%increase in Hen annual costs.
