摘　　要：说明了有机蒸气膜分离的原理、性能、应用．介绍了大庆炼化公司应用有机蒸气膜分离技术回收低压瓦斯中的C3、C4．原料气进行净化后通过膜装置对瓦斯中的C3以上组分富集，然后通过压缩机把渗透气送到ARGG装置回炼，投用后取得了较大经济效益．The recovery technology of volatile organic compounds was introduced. The principle, performance and application fields of vapor membrane separation thecnology were expounded. The application in the recovery of C3, C4 hydrocarbons from low presure gases in Daqing Refining＆Chemical Company wad discribed. The feed gas was purifyed, and C3, C4 were enriched by using membrane unit, and then C3, C4 was sent to ARGG plant by compressor. More profit from the gas membrane separation technology attained.
