Research and application analysis on the pollution control of tail gas emissions from CO2 capture absorber
Organic amine carbon dioxide capture technology is widely used for industrial carbon capture due to its mature technology, however, the emission of absorbent and degradation products can affect the carbon dioxide capture efficiency and increase the environmental health risk.

| description | Organic amine carbon dioxide capture technology is widely used for industrial carbon capture due to its mature technology, however, the emission of absorbent and degradation products can affect the carbon dioxide capture efficiency and increase the environmental health risk. This paper summarizes the types and current status of pollutant emissions from chemical absorption systems, and explores the effects of flue gas condensation nucleation occurring in different salt solutions, carbon dioxide concentration in the flue gas, lean liquid loading, liquid-to-gas ratio, flue gas inlet temperature of the absorber tower, and temperature of the lean liquid on pollutant emissions from carbon dioxide chemical absorption systems by means of a small test experiment with a flue gas treatment design capacity of 3.6 Nm3/h. At the same time, amine escape from a coal-fired power plant with a flue gas treatment capacity of about 1.4 million Nm3/h was also studied, and the control effects of different pollutant emission control measures were compared, and the best pollutant emission control measure was the combined control process of “secondary water washing + 7-meter dry bed”, with a reduction of organic amine absorber loss by 716.5 mg/Nm3, a reduction of 71.65 % compared with the “primary water washing” control process. |
