초록

본 연구는 그 동안 주로 석유화학의 개질공정 등에서 적용되었던 이산화탄소 흡수분리기술을 연소배가스에 적용하기 위한 기본적인 연구로서, 이산화탄소의 흡수분리공정에 일반적으로 많이 사용되는 흡수제인 MEA(mono-ethanol amine)를 연소배가스에 적용하였을 경우 예상되는 열화, 재생에너지 및 흡수능력 등의 문제점을 개선하기 위하여 거론되는 입체장애아민인 AMP(2-amino 2-methyl 1-propanol) 수용액과 이산화탄소와의 흡수평형 특성을 비교 평가하였다. 실험결과 AMP는 MEA에 비하여 이산화탄소의 흡수능력이 반응 메카니즘에 의하여 약 2배 정도 증가함을 확인하였고, 연소배가스와 같은 저농도 이산화탄소 흡수분리공정 설계에 필요한 흡수평형자료를 부분적으로 제시하였다.

This research was basically carried out to extend the application of $CO_2$ absorption processes for flue-gas system, which are mainly applied to a reforming process in petro-chemical industries. In general, MEA absorbent has some problems in flue-gas treatment, such as, degradation, regeneration energy and absorption capacities. As we known, sterical hindered amine, typically AMP (2-amino 2-methyl 1-propanol), have a good potential to improve these problems. In this paper, the characteristics of $CO_2$ absorption in aqueous AMP solution were measured and compared with that of MEA. It has been found that the $CO_2$ absorption capacity in AMP is double than that of MEA in the low $CO_2$ partial pressure system such as flue-gas. Also, the equilibriums of $CO_2$-AMP system were partially suggested, which are essentially needed to design the absorption process.
