摘要	Organic amine absorption is an efficient and environmentally friendly flue gas desulfurization technology, and the analysis, optimization and energy consumption evaluation of the flue gas SO2 capture process from the perspective of system engineering have not been reported in detail. In this paper, SO2 capture process of flue gas was studied with N-methyldiethanolamine (MDEA) as the absorbent. The effects of MDEA concentration, temperature, and SO2 desorption rate on the SO2 capture were investigated. The results show that the optimized parameters for SO2 absorption are as follows: MDEA concentration, feed temperature of flue gas and absorbent are 30%(mass), below 45 and 41, respectively. Increasing of the SO2 desorption ratio is at the expense of the low SO2 desorption purity and the high energy consumption of absorbent regenerative process, since water gasification is the main reason for the high energy consumption. In order to solve the problem of high energy consumption in the regenerative process, the modified process with heat pump technology was proposed. The energy consumption of absorbent regeneration can be reduced by 47%, TAC can be reduced by 9.93% in the heat pump assistant desorption process. It is expected from the study to strengthen the development of the industrial application of SO2 capture of organic amine system. © 2021, Editorial Board of CIESC Journal. All right reserved.
