본 연구에서는 구아니딘계 초염기인 1,1,3,3-테트라메틸 구아니딘 (TMG)과 에틸렌 글라이콜로 구성된 비수계 흡수제를 충진탑에 적용하여 이산화탄소 흡수특정을 고찰하였다. 흡수탑은 내경이 1 in이고 높이는 0.6 m이며 탑 내부는 0.16 in × 0.16 in의 규격을 갖는 다공 충진물로 채웠다. 흡수탑을 통한 이산화탄소 제거 효율에 대한 흡수제 농도, 조업온도 등의 영향 뿐 아니라 이들이 물질전달 저항에 미치는 영향을 고찰하였다. 이산화탄소에 대한 TMG의 로딩값은 약 1 molCO2/molTMG에 달하였으며 이산화탄소가 적게 로딩된 흡수제에서는 총괄 물질전달 계수가 TMG의 농도에 비례하였으나 일정 로딩값 이상에서는 총괄 물질전달계수가 오히려 감소하였다. 이는 흡수제의 이산화탄소에 대한 로딩값에 따른 흡수제 점도 증가로 인한 제에서의 물질전달 저항 증가로 해석할 수 있다.
