摘要:

中原油田第四气体处理厂是国内自行设计的一套以回收乙烷为主的大型轻烃回收装置，该装置通过两年的运行标定，各项实际指标均优于设计指标。通过介绍中原油田第四气体处理厂轻烃回收设计特点及深冷工艺的关键环节，探讨提高产品收率、降低能耗、减少投资的技术和途径。

Abstract:

The Fourth Natural Gas Processing Plant of Zhongyuan Oil Field is a large - scale unit of recovering C2+ NGL, which was designed by itself in our country. Running of two years shows that all of the technical indexes are better than design indexes. The art
