Abstract
Increasing emission of significantly effects the global warming. Chemical absorption is one of separation methods of from the industrial flue gases. In this study, the removal efficiency as well as the absorption amount of aqueous AMP (2-amino-2-methyl-1-propanol) solutions were measured using the continuous absorption and regeneration apparatus. We investigated the effect of aqueous AMP+AEPD(2-amino-2-ethyl-1, 3-propanediol) and AMP+TIPA (triisopropanolamine) solutions to enhance absorption characteristics of AMP. As a result of this study, the absorption amount and removal efficiency were increased with adding TIPA into 30 wt.% AMP. The absorption amount and removal efficiency of aqueous 30 wt.% AMP+5 wt.% TIPA solution were and 91.1%, while those of aqueous 30 wt.% AMP solution were and 89.3%. In addition, aqueous 30 wt.% AMP+5 wt.% TIPA solution used in the study revealed the high stripping efficiency, which was almost 98%, at the temperature of . Thus, the temperature of regenerator should be operated at .
