Research progress of carbon capture technology based on alcohol amine solution.

• Carbon Capture Carbon Capture, Utilization and Storage (CCUS) technology technology is systematically introduced, focusing on the carbon capture technology based on alcoholic amine solution and analyzing the advantages and shortcomings of the technology; • Alcohol-amine carbon dioxide absorbers are divided into five types: single-phase alcohol-amine solution, alcohol-amine + organic solvent, alcohol-amine + ionic liquid, mixed alcohol-amine solution and phase-change alcohol-amine, which systematically introduces the research progress of the current alcohol-amine absorbers and points out the development direction of the absorbers; • The carbon capture process and system components are systematically introduced, and the influence of system parameters on the capture effect is summarized based on the current relevant research articles; • In view of the limitations of the current carbon capture system, some reasonable ideas for optimizing the carbon capture system are summarized. CO 2 emissions are the primary cause of global warming and climate anomalies. Reducing CO 2 emissions to arrest or mitigate global warming has been a hot topic of discussion. Carbon Capture, Utilization and Storage (CCUS) is an effective carbon reduction technology, in which the chemical absorption method based on amine solution is the most promising and widely used carbon capture technology among the CCUS technologies, but the high energy consumption of its regeneration increases the cost of carbon capture and restricts the promotion of CCUS technology. This paper firstly introduces the process of CCUS technology, and reviews the current development of carbon capture technology based on alcoholic amine solution from three perspectives, including the development of absorbent, the influence of the operating parameters of the carbon capture system on the capture effect, and the optimization of the carbon capture system, with regard to the carbon capture technology of alcoholic amine solution. Research results show that the current popular optimization directions include: developing new absorbents with high CO 2 absorption rate and low regeneration energy consumption; analyzing the material, temperature and energy distribution of the system through thermodynamic methods, such as exergy analysis and pinch analysis, to properly operate the whole carbon capture system; optimizing the traditional carbon capture system, for example, by changing the feed method of the absorbent to achieve a more efficient capture, introducing energy-saving equipment, such as heat pumps, to increase the energy efficiency of the system or by coupling it with solar power, LNG, or other clean energy sources, to achieve the reasonable integration of multistage energy sources.
