摘　　要：本文通过Aspen Plus模拟软件对沼气用MDEA(N-甲基二乙醇胺)法脱除二氧化碳净化制取车用燃气的工艺过程进行模拟计算,通过软件灵敏度分析可以得出本文最佳吸收液温度为30℃、最佳的溶液循环量为2.5t/h、吸收液的最佳浓度选择为17%、原料气进口温度对于净化气中CO2浓度的影响较小,通过对工艺流程的模拟,可以为下一步制取生物天然气的实验研究提供理论依据。In this paper, Aspen Plus was employed to simulate the processes of making fuel gases for automobiles by de--carbonization and purification of biogases under MDEA. The temperature gra- dients of the absorption tower and regeneration tower were obtained by simulation. The software sen- sitivity analysis showed that the optimal temperature of absorbing liquid is 30℃, the optimal solution circulation is 2.5t/h and the optimal concentration of absorbing liquid is 17% The inlet temperature of the feed gas has not much impact on the CO2 concentrations of the purified gas. The simulation of the technical process will provide a theoretical basis for the experimentation on making fuel gases from bio- gases.
