醇胺法吸收烟道气中二氧化碳的研究进展
Research progress on absorption of carbon dioxide in flue gas by alcohol amine method
摘要
Abstract
Carbon dioxide(CO2)capture,utilization and storage technology is one of the main technological ways to achieve the carbon peaking and carbon neutrality goal.Alcohol amine method to absorb CO2 in flue gas is the most mature and widely used CO2 capture process,which has been commonly used in the industrial decarbonization of flue gas.Absorbents are the core elements of the alcohol amine method,and the selection of suitable absorbents has become a key research direction at present.The classification and working principles of alcohol amine absorbents and the process flow of CO2 absorption in flue gas were reviewed.The performances of a binary mixed absorption system of ethanolamine(MEA)and methylenediamine(MDEA)as absorbents and MEA and MDEA as main absorbents respectively were analyzed in depth.A series of optimization measures,including adding activators and additives into the alcohol amine solution,using new absorbents,were proposed to address the drawbacks of low regeneration efficiency,high desorption energy consumption,easy corrosion of absorbents and high recovery costs in the alcohol amine method to absorb CO2 in flue gas.Finally,the development of the alcohol amine method to absorb CO2 in flue gas was discussed,so as to provide a reference for the development of high-efficiency alcohol amine absorbents.关键词
