Exergoeconomic methodology for analysis and optimization of process systems

This paper describes the progress of a systematic exergoeconomic methodolog y 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-coordina ting optimization strategy is introduced to analyze and optimize the total process system A retrofit of an aromatic separation system is taken as an e xample to illustrate this method.
