Removal characteristics of CO2 using aqueous MEA/AMP solutions in the absorption and regeneration process

The carbon dioxide （CO2） removal efficiency, reaction rate, and CO2 loading into aqueous blended monoethanolamine （MEA） ＋ 2-amino-2-methyl-l-propanol （AMP） solutions to enhance absorption characteristics of MEA and AMP were carried out by the absorption/regeneration process. As a result, compared to...

description The carbon dioxide （CO2） removal efficiency, reaction rate, and CO2 loading into aqueous blended monoethanolamine （MEA） ＋ 2-amino-2-methyl-l-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.
