Recovery of the refinery dry gas is an important method to utilize natural resources more effectively and improve economic benefits. How to reclaim and utilize the refinery dry gas in an effective way has become a critical issue recently. Comprehensive utilization of refinery dry gas is overviewed from two aspects in this paper. The separation technologies such as cryogenic separation, absorption separation and adsorption separation as well as the direct-use technologies such as the production of ethylbenzene and epoxyethane are presented and discussed. In order to obtain the best economic and environmental benefits,different petrochemical enterprises should choose different recovery technologies based on their own characteristics.
