Abstract

In this study, the effect of alkanolamine additives, 2-amino-2-methyl-1-propanol (AMP) and 2-amino-2-methyl-1,3-propanediol (AMPD) on $CO_2$ absorption rate of $K_2CO_3$ solution and the formation of $KHCO_3$ crystals was investigated. The normalized $CO_2$ flux and the equilibrium $CO_2$ partial pressure were measured for 5 wt% additives and 30 wt% $K_2CO_3$ mixtures using a wetted-wall column unit at $40^{\circ}C$ and $60^{\circ}C$. Both additives showed the increased $CO_2$ absorption rate and lowered the equilibrium $CO_2$ partial pressure acting as promoters. Besides, AMPD which has two hydroxyl groups enhanced the formation of $KHCO_3$ solid product separated from the $CO_2$-rich solution from the results of batch cooling crystallization experiments.

본 연구에서는 입체장애 알카놀아민 첨가제인 2-아미노-2-메틸-1-프로판올(2-amino-2-methyl-1-propanol, AMP)과 2-아미노-2-메틸-1,3-프로판디올(amino-2-methyl-1,3-propanediol, AMPD)가 $K_2CO_3$ 흡수액의 이산화탄소 흡수속도와 $KHCO_3$ 고체염의 석출에 미치는 영향에 대해 고찰하였다. 흡수온도 $40^{\circ}C$와 $60^{\circ}C$에서 wetted-wall column을 이용하여 흡수속도와 이산화탄소 평형분압을 측정한 결과, 30 wt%의 고농도 $K_2CO_3$에 대해 5 wt% AMP와 AMPD는 흡수속도를 증가시키는 동시에 평형분압을 감소시켜, 흡수촉진제로서 흡수성능을 향상시키는 것으로 확인되었다. 또한, 회분식 냉각결정화 실험 결과, 복수의 히드록실기를 포함하는 AMPD가 흡수액을 냉각시 석출되는 $KHCO_3$ 고체염의 양을 증가시키는 것으로 나타났다.
