摘　　要：炼厂干气是重要的化工原料和燃料。本文介绍了深冷分离、双金属络合分离、溶剂抽提、中冷油吸收、膜分离、变压吸附以及联合装置等炼厂干气的分离回收技术 ,综述了采用炼厂干气制乙苯、对甲基乙苯、环氧乙烷、二氯乙烷、氮肥、甲醇等综合利用方法 ,指出合理利用炼厂干气是增加炼厂经济效益的一条有效途径。Refinery dry gas is an important chemical feedstock and fuel. The separation and recovery technologies such as cryogenic separation, bimetallic complex formation separation, solvent extraction, inter-condensate oil absorption, membrane separation, pressure swing adsorption and integral equipment are introduced. Comprehensive utilization of refinery dry gas to prepare ethylbenzene,p-methyl ethylbenzene, ethylene oxide, ethylidene chloride, nitrogen fertilizer and methanol are reviewed. It is pointed out that to utilize reasonably dry gas is an effective way to increase benefit for refinery.
