摘　　要：在石油开采行业中,富含CO_(2)的油田采出气一直是人们难以利用的资源,大部分油田对其采取直接排放或燃烧的处理方式。针对上述问题,为了有效利用资源,减少排放,提出了压缩冷凝与膜分离耦合回收CO_(2)和烃组分,并将其用于某大型油田采出气中,同时利用Aspen HYSYS模拟软件,对压缩冷凝与膜分离耦合回收工艺流程进行模拟优化。结果表明:在冷凝压力为2.0 MPa条件下,制冷温度-24℃,膜面积399 m^(2),压缩机总功率250 kW,CO_(2)回收率为81.56%,烃组分回收率为97.10%,设备投资约2.79×10^(6) CNY,公用工程费约为1.29×10^(6) CNY/a,年经济效益约为9.47×10^(6) CNY。In the oil production industry,CO_(2) rich oilfield produced gas has always been a difficult resource for people to use,and most of the oil fields adopt direct emission or combustion treatment.In view of the above problems,in order to effectively utilize resources and reduce emissions,the coupling of compression condensation and membrane separation was proposed to recover CO_(2) and hydrocarbon components,which was used in the produced gas of a large oil field.At the same time,Aspen HYSYS simulation software was used to simulate and optimize the coupling process of compression condensation and membrane separation.The results show that:under the condition of condensation pressure of 2.0 MPa,refrigeration temperature of-24℃,membrane area of 399 m^(2),total compressor power of 250 kW,CO_(2) recovery rate of 81.56%,hydrocarbon recovery rate of 97.10%,equipment investment of about 2.79×10^(6) CNY,utility cost of about 1.29×10^(6) CNY/a,annual economic benefit of about 9.47×10^(6) CNY.
