摘　　要：介绍了有机蒸气渗透膜原理和分离过程特点，分析了膜法油气回收系统在汽油、石脑油、苯系物等挥发性有机液体的储运、运输等环节上的工业应用。Volatile organic compounds （VOCs）are one of the main sources of photochemical reaction in the atmosphere leading to various environmental hazards, On the other hand, these VOCs have good commercial value. Growing environmental awareness put up stringent regulations to control the VOCs emissions. A membrane based technology to reduce these emissions was developed for the whole chain distribution from the refinery to the tank farm, to the petrol station and during car refueling.
