摘　　要：空分设备有效能损失主要存在流体的压缩与膨胀、热交换、精馏及节流减压等。通过节能改造和优化操作,提高了有效能的利用率,从而达到降低空分设备能耗的目的。Exergy loss in an air separation unit mainly derives from the compression and expansion processes of fluid, heat exchange, rectification and throttling. After energy-saving modification and operation optimization, the exergy loss has been reduced, and as a result, a decrease of air separation unit＇s energy consumption has been realized.

关 键 词：空分设备 有效能损失 节能 优化
