【Abstract】 The main advantages and principles of the MDEA carbon dioxide removal process are described in the paper.The process conditions and technical data are also presented.After CO₂ removal the CO₂ content in the purified gas is less than 100 ppm （minimum 5 ppm）; the recovery of CO₂ is above 99% and the purity of CO₂ recovered exceeds 99.8%.This will benefits the CO₂ balances in the ammonia synthesis unit and methanation system as well as the improvement of the middle and small sized ammonia plants.更多还原
