提高粗苯工序换热效率的方法

摘要

针对粗苯工序列管式换热器设备本身缺陷，新增加2组螺旋板换热器，极大地提高了贫富油换热效率，降低了粗苯工序能耗。%Regarding to the defects of tube heat exchangers in crude benzol unit,two sets of spiral plate heat exchangers are additionally provided, which significantly improves the heat exchange efficiency between lean and rich oil,and reduces energy consumption of this unit.
