In order to explore the application value and impact of MDEA decarbonization technology in the process of natural gas production from coke oven gas,this paper introduces the basic principles and technical routes of natural gas production from coke oven gas,analyzes the problem of high carbon dioxide content,and expounds the principle and advantages of using MDEA decarbonization technology for carbon dioxide removal.It also designs a set of experimental procedures to carry out MDEA decarbonization treatment on coke oven gas,and tests the key indicators such as carbon dioxide removal rate,gas production rate,energy consumption under different operating parameters.The experimental results show that MDEA decarbonization technology can effectively remove carbon dioxide from coke oven gas with a removal rate of more than 90%.When the concentration of decarbonization agent is 25%,the operating temperature is 40 ℃,and the operating pressure is 1.5 MPa,the gas production rate is the highest and the energy consumption is the lowest.Therefore,MDEA decarbonization technology could improve the gas production rate of natural gas,reduce energy consumption,and enhance the carbon dioxide removal rate for coking plants.
