摘　　要：针对河南龙宇煤化工有限公司一期50万t/a甲醇装置排放CO2废气的问题,通过采用变压吸附生产工艺,经脱硫、净化、冷凝、提纯,脱去烃类、CO、氮氧化物等杂质,获得高纯度液态CO2产品。通过该工艺回收利用工业CO2废气,实现了CO2的综合利用。该项目投用以来,运行效果较好,生产效益实现了最大化。As for the waste gas CO2 discharge of Phase I 500 000 t / a methanol plant of Henan Longyu Coal Chemical Co.,Ltd.,PSA process was applied for desulphurization,purification and condensation so as to remove the impurities as hydrocarbons,CO,NOxand etc. and to obtain high purity liquid CO2 product. By using this process,the waste gas CO2 was recovered for comprehensive application. Since the project was put into operation,it had run with good returns and maximized production benefit.
