Through analysis of technical features,recovery rate,emission standard,economy and safety of commonlyused oil recovery methods,a new high-efficiency recovery process combining condensing and resin adsorption is proposed,accordingly condensing and absorption gas recovery device in gas station is developed.Simulation with typical oil and gas components in gas station shows the best condensation point is-10 ℃.The integration result indicates that with the application of resin adsorbent,the desorption rate of oil and gas is higher than 95 ％,solving the problem of energy consumption and short life of adsorbent and meanwhile increasing the recovery rate of oil and gas,thus realizing the optimization of integrated process of condensing,absorption and energy saving.Actual application results show that the estimated value of light gas exhausted from condensing and absorption gas recovery device is less than 5 g/m3,which reaches a recovery rate of 99％,and at the same time its energy consumption is 10％ lower than that of similar products.（4 Tables,4 Figures,6 References）
