Abstract： The absorption-adsorption integrated process has many industrial applications in the field of oil and gas recovery because of its good recovery effect. The current absorption-adsorption integrated process has many process defects， such as not suitable for low import flow， unstable inlet flow and high energy consumption. To deal with these problems， the process has been optimized. A semi-process and full-process alternate mode was designed for absorption-adsorption integrated oil and gas recovery process. Optimized process can run in half-flow and full-flow alternate mode during operation， which will reduce the energy consumption and adapt to more conditions. The optimized process has better application prospect.

隨着我国油气储存与运输行业的不断发展，生产过程中油气蒸发损耗所带来的问题也越来越受关注^[1-3]。油气回收是减少油气蒸发损耗比较理想的控制技术^[4-5]。当前，基于集成工艺的油气回收技术在油气回收工业中有着广泛的应用^[6-8]。吸收-吸附集成工艺因其有较好的回收效果在油气回收领域有很多的工业应用^[9-10]。该工艺采取在吸收塔后面增加一个吸附塔，将出口尾气通入吸附塔进行深度吸附后达标排放^[11]。该集成工艺相比于比单一吸收法有更高的回收效率，比单一吸附法有更高的安全性，综合效益显著^[12]。但目前的吸收-吸附集成油气回收工艺适合应用于油气处理量大的工况，对于油气处理量少、系统进气不稳定、进口油气浓度小等工况时效果不是很理想。同时，当前工艺一般吸收过程与解吸过程同时进行，能耗相对比较高。……
