The carbon dioxide (CO2) removal efficiency, reaction rate, and CO2 loading into aqueous blended monoethanolamine (MEA) + 2-amino-2-methyl-1-propanol (AMP) solutions to enhance absorption characteristics of MEA and AMP were carried out by the absorption/regeneration process. As a result, compared to aqueous MEA and AMP solutions, aqueous blended MEA + AMP solutions have a higher CO2 loading than MEA and a higher reaction rate than AMP. The CO2 loading of rich amine of aqueous 18 wt.% MEA + 12 wt.% AMP solution was 0.62 mol CO2/mol amine, which is 51.2% more than 30 wt.% MEA (0.41 mol CO2/mol amine). Consequently, blending MEA and AMP could be an effective way to design considering economical efficiency and used to operate absorber for a long time.
通过吸收/再生过程，研究了二氧化碳（CO₂）去除效率、反应速率以及CO₂负载到单乙醇胺（MEA）+2-氨基-2-甲基-1-丙醇（AMP）混合水溶液中的情况，以增强MEA和AMP的吸收特性。结果表明，与MEA水溶液和AMP水溶液相比，MEA+AMP混合水溶液具有比MEA更高的CO₂负载量以及比AMP更高的反应速率。18 wt.% MEA + 12 wt.% AMP水溶液富胺的CO₂负载量为0.62 mol CO₂/mol胺，比30 wt.% MEA（0.41 mol CO₂/mol胺）高出51.2%。因此，考虑到经济效率，将MEA和AMP混合可能是一种有效的设计方法，可用于长时间运行吸收器。
