基于分析的板式换热器热力学性能研究

Thermodynamic performance research of a plate heat exchanger based on exergy analysis

换热器作为石化、制药、热能工艺体系的重要构成单元,在热量传导、营造反应环境方面发挥重要的作用。本研究采用分析方法,对芳烃中产生的苯石化流程中的板式换热器进行了热力学性能分析。结果表明,具有流体相变的换热器比单相流体具有更好的性能。

Thermodynamic performance analysis was taken for a plate heat exchanger with the method of exergy analysis. Exergy utilization analysis was taken for heat exchangers in Benzene producing in aromatic hydrocarbon. Our results show that heat exchangers with fluid phase change had better performance than these of single-phase fluid.
