摘要： 对干气回收装置通常所采用的浅冷油吸收法和变压吸附法的基本原理和工艺流程进行了比较，阐述了变压吸附与浅冷油吸收耦合回收干气中碳二的工艺技术。以某干气回收装置为例，对该工艺的技术特点做了介绍，从流程、能耗、占地等方面对干气回收的两种方法进行了对比说明。与传统的干气回收方法相比，变压吸附与浅冷油吸收耦合工艺有一定的优势，具有能耗较低、大幅降低吸收剂用量、减少装置建设工程费等特点，对工程实践具有指导意义。

Abstract: The basic principle and process of cold oil absorption method and PSA method in dry gas recovery plant was compared. A coupled process technology of PSA and cold oil absorption for recovering C2+ was introduced. Taking a dry gas unit as an example，the technical characteristics of this new method was discussed in terms of process configuration，energy consumption and area. Compared with the traditional dry gas recovery method，the coupled process technology of PSA and cold oil absorption has advantages in low energy consumption，greatly reduced amount of absorbent，and low plant installation cost.
Key words: dry gas, recovery, cold oil, absorption, PSA, energy consumption
