乙二醇装置中环氧乙烷进料/产品换热器的选型对于反应气热量的回收以及能量合理利用具有重要作用。以某乙二醇装置为例，采用ASPEN、HTRI等计算软件对比了单浮头式和折流杆式环氧乙烷进料/产品换热器的传热效率、有效平均温差、圧降等。结果表明，单浮头式换热器的传热效果更优，经济效益更好，为乙二醇生产企业环氧乙烷/产品换热器的选型提供了参考。

Type selection for feed product exchanger of ethylene oxide (EO) reactor in ethylene glycol (EG) plants is critical to the recovery of reaction gas heat and the rational utilization of energy.Taking a certain EG plant as an example, ASPEN and HTRI software are employed to compare the heat transfer efficiency, EMTD and pressure drop of different kinds of EO reactor feed/product exchangers.The results show that single floating head heat exchanger shows better heat transfer efficiency and economic benefit.A reference for the type-selection of EO reactor feed/product exchanger in EG production companies is provided.
