摘　　要：垃圾填埋气是垃圾厌氧发酵甲烷化分解的产物,主要成分为CH4和CO2。对垃圾填埋气的处理可采用MDEA法脱碳工艺进行脱碳净化,回收其中的CO2并制成干冰。利用AspenPlus软件对垃圾填埋气脱碳工艺的换热网络进行稳态模拟,对模拟结果进行能量平衡分析,并利用夹点技术对系统用能做进一步的探讨。Landfill gas is the product of methanation by anaerobic fermentation,and the main components are CH4 and CO2.The MDEA process ISs used to remove CO2 from landfill gas and recycle it into dry ice.Aspen Plus software is used to simulate the heat exchange network of landfill gas decarbonization process.The energy balance of simulation results is analyzed,and the energy consumption of the system is further discussed by pinch technology.
