Abstract: The multi-component incompatible phenomena of a single mass exchanger was analyzed and the method for the optimal flow rate of lean stream was proposed. Genetic algorithm was used to optimize the MEN. To solve the incompatible phenomena the method of encoding the number of trays of each mass exchanger was proposed. The method was illustrated with an example. In contrast to the result previously published, the final network obtained was the cheapest. Furthermore, the method could also deal with incompatible multi-component MEN.
