摘　　要：通过适当增加中压氨冷凝器 (E10 9)后设备的处理能力来克服E10 9换热面积不足这一设计缺陷 ,使中压放空的氨损失由 11.4 3%降至 5 .34% 。The drawback of inadequate heat exchange surface of the medium pressure ammonia condenser (E109) is overcome by the appropriate increase in the treatment capacity of the equipment downstream of E109, so that the loss of ammonia through medium pressure venting reduces from 11.43% to 5.34%, and the retrofit result is quite remarkable.
