Abstract:This paper introduces a new approach for optimizing heat exchanger networks (HEN), which combines pseudo-temperature enthalpy diagram method and superstructure method. The approach focusing on the minimization of total annual cost, uses a simplified superstructure to solve the sub-networks which obtained by a pseudo-temperature enthalpy diagram, and also involves multi-stream heat exchangers as exchange units. An example taken from literature is studied here. The result of the study indicates the effectiveness and advantages of this methodology.
