Carbon dioxide emissions are increasing rapidly, which is a serious threat to human survival and climate change, and how to reduce carbon emissions is a hot concern. The chemical absorption method is one of the main methods for capturing CO2. The essence of CO2 removal is the use of an alkaline absorber solution to contact and chemically react with the CO2 in the flue gas reversely, forming unstable salts, which will decompose in the reverse direction to release CO2 under certain conditions, thus achieving the separation and removal of CO2 from the flue gas. The development of chemical absorption method technology using alcohol amine solution as absorbent has been relatively mature, and the separation effect is good and simple to operate, which is widely used in electric power, iron and steel, cement and chemical industries. Alcohol amine solutions are the core of the chemical absorption method, and the alcohol amine solutions currently used in industrial abatement include primary alcohol amine solutions, secondary alcohol amine solutions, tertiary alcohol amine solutions and steric hindered amines. Four typical alcohol amine solutions were listed in this paper, and the current status of domestic and international research on amine solutions for low concentration flue gas absorption was reviewed. The KM-CDR process of Mitsubishi Heavy Industries, the desulphurization and decarbonization process of Shell Consolv, the supporting process of Dow Chemical Ucarsol solvent, the supporting process of Siemens amino acid salt solution and the ECO2 process of Powerspan were introduced, while the oxygen-enriched combustion technology of Alstom was summarized. The research on carbon capture in China is relatively short, under the promote of "carbon peaking and carbon neutrality goals"，carbon emission reduction has become the focus and hotspot of domestic research in recent years, the research results of a number of universities and research institutes, such as Zhejiang University, North China University of Electric Power, Beijing University of Chemical Technology and China University of Mining and Technology, were listed in the paper. At present, the chemical absorption method has been applied in industry, and a number of carbon capture demonstration projects have been built in China. The 10 000 tons/year CO2 capture demonstration project of Huadian Jurong Power Plant, the 150 000 tons/year CO2 capture demonstration project of Guohua Jinjie Power Plant and the 40 000 tons/year coal-fired CO2 capture and oil drive demonstration project of Shengli Oilfield were systematically introduced. The scale of CO2 capture demonstration projects for coal-fired power plants at home and abroad is generally small, with only three million tons demonstration projects, among which Sinopec has built China′s first million tons carbon capture project, which is a milestone for the development of China′s carbon capture industry. In the field of CO2 capture by organic amines, research should be focused on five aspects: energy consumption and degradability reduction of absorber regeneration, comprehensive use and recovery of thermal energy in the capture system, development of high flux CO2 capture and absorption reactors, and control of absorber escape, to develop low energy consumption, low loss and low cost CO2 capture technologies, promote multi-industry engineering demonstrations, and lay the foundation for the large-scale promotion of CO2 capture technologies for coal-fired flue gas.
