摘　　要：研究了采用柴油低温临界吸收法回收装车挥发油气的效果。实验结果表明:按装车挥发油气中的总烃体积分数为20.88%、装车挥发油气流量为280 m3/h、年运行时间为2 668 h计,装置年回收油气量为291 t,装置年最大运行功率为206.770MW,装置投资回收期为3 a;处理后净化气中的总烃体积分数为1.24%,排放质量浓度低于25 g/m3,油气回收率达95%。处理后净化气满足GB 20950—2007《储油库大气污染物排放标准》,取得了较好的环保效益和经济效益。The recovery effect of oil vapor in gasoline shipping by the process of low temperature critical absorption with diesel oil was studied.The experimental results show that：When the volume fraction of the total hydrocarbon in oil vapor is 20.88％,the vapor flow is 280 m^3/h and the annual running time is 2 668 h,the amount of recovered vapor is 291 t and the maximum annual operating power of the device is 206.770 MW,and the payback period is 3 a; The volume fraction of the total hydrocarbon in the treated gas is 1.24％,its mass concentration in the exhaust gas is lower than 25 g/m^3,and the recovery rate of oil vapor is 95％.The treated exhaust gas can meet the national emission standards of GB 20950-2007.
