摘　　要：对可能终端应用的CO2分离技术进行了简要概述,同时结合我国炼油厂烟道气的特点,筛选出3种适合我国炼油厂的可行的分离技术,即适合回收低浓度CO2的化学吸收法和膜吸收法,适合回收制氢尾气的变压吸附法(PSA法),并进行了系统阐述。根据我国炼油厂碳排放现状,提出了相应的发展建议。To ease global warming, CO2 emissions from large sources must be limited. The petroleum refining industry as one of the largest contributors to anthropogenic CO2 emission is forced to implement CO2 mitigation measures. At present, CO2 separation from point source emissions has been recognized as one of several strategies necessary for mitigating unfettered release of greenhouse gases （ GHGs ） into the atmosphere. Therefore, the possible CO2 separation technologies for end-of-pipe applications are briefly reviewed. According to the characteristics of flue gas from the refineries in China, three feasible CO2 separation technologies are selected, such as the chemical absorption and membrane absorption methods for low concentration flue gas and pressure swing adsorption （ PSA ） for off gases of hydrogen manufacturing unit. Based on the current status of CO2 emission from petroleum refineries in China, some suggestions are proposed as well.
