In recent years, reduced the gas station Evaporation loss is a new research area for oil gas storage and transport specialist in reducing the losses of petroleum products aspect. This article through to the losses of petroleum products reason and the gas station oil gas volatility characteristic analysis, proposed several methods about reduces evaporation loss of gas station. The paper primary coverage is as follows: Firstly, analyzed the oil evaporation loss reason and the type, and had the volatility key spot in view of the gas station oil gas volatility characteristic, proposed through the collection oil steam to reduce the gas station evaporation loss .And proposed some oilgas collection systems in view of the gas station oil volatility key spot. Secondly, in view of collection oil gas processing, proposed several methods about oilgas recovery. Introduced specifically several kind of oilgas recovery method and the simple technical process, and aim at the gas station suitable situation, carries on the synthesis comparison to several recycling methods. Moreover also introduced technology of gas recovery from the gas station and its application progress at home a
