Research progress of amine escape control technology by chemical absorption method
The escape of CO2 chemical absorption absorbent and its degradation products will lead to the high cost of absorbent,and the emission of amines will pollute the atmosphere,which will increase the operating cost and pollute the environment.This paper mainly introduces the types,principles and control methods of amine escape.Water washing and traditional demister are commonly used control methods at present,which can effectively remove gas and physical entrainment escape,but aerosol escape has not been well solved because of its small particle size and large escape volume.At present,the commonly used control methods include increasing separation equipment,controlling operation parameters,adding additives,and intermediate cooling.The future development trend is to still put physical methods,such as quenching,high-frequency electric field and other methods,to control the escaping gas after the absorption tower or water washing tower without changing the previous reaction conditions.On the premise of taking into account the capture efficiency of CO2 absorption method,the economic and environmental benefits will be improved and technical support will be provided for industrial development.
