摘　　要：针对油品在储运和销售过程中,部分轻烃组分易挥发进入大气,造成资源浪费和环境危害的问题,利用化工流程模拟软件Aspen Plus模拟S1、S2和S3三种油气样品的冷凝过程,并对冷凝法油气回收工艺流程及其冷凝温度设置进行优化。研究结果表明:3种差异较大的油气组分在冷凝温度达到-110℃时均可达到国家排放标准要求;冷凝法油气回收工艺流程宜设置为4阶段冷凝,1～4阶段温度分别设置为4℃、-40℃、-80℃和-110℃时,既能保证油气回收率和尾气浓度符合国家标准要求,又能使油气回收的能耗控制在较低水平。As for the problem in storage and sale process of oil products, part of light hydrocarbons composition will easily evaporate into the atmosphere, resulting in a waste of resources and environmental hazards. Chemical process simulation software Aspen Plus is used to simulate the condensation process of 3 light gas samples of S1,S2 and S3, and optimization analysis for light gas recovery processes with condensation method is performed. The results show that 3 hydrocarbon components in great difference can reach the national emission standards when condensing temperature reaches -110 ℃. The light gas recovery process with condensation method should be arranged in four stages, the temperatures should be set to 4 ℃, -40 ℃, -80 ℃ and -110 ℃ respectively, which can not only ensure the light gas recovery rate and emission concentration meet national standards, but also control the energy consumption for light gas recovery at a relatively low level. （1 Table, 7 Figures, 17 References）
