Exergoeconomic methodology for analysis and optimization of process systems

Abstract This paper describes the progress of a systematic exergoeconomic methodology for analysis and optimization of process systems. Based on the three-link-model, by applying a reversed exergy costing method to process systems, a hierarchical exergoeconomic model is developed and the decomposing-coordinating optimization strategy is introduced to analyze and optimize the total process system A retrofit of an aromatic separation system is taken as an example to illustrate this method.
