摘要
介绍了茂名石化乙烯裂解装置尾气膨胀制冷工艺。同时考察了尾气节流膨胀制冷和膨胀机膨胀制冷对分馏分离器、氢气回收系统及其它系统的影响。结果发现 ,尾气膨胀机膨胀制冷对深冷分离的效果好于节流膨胀制冷 ,可节约能耗 ,提高装置的负荷 ,是一种很好的制冷方法。
This paper introduces the expansion refrigeration process of tail gas in the ethylene plant of Maoming Ethylene Project,and analyzes the effect of different expansion refrigeration modes on cryogenic separation.Expansion refrigeration through a tail gas expander can reduce energy consumption and increase plant capacity and has a desirable effect on the result of cryogenic separation process.
