초록

본 연구에서는 용매 흡수법을 이용한 이산화탄소 포집공정에 액상 용매의 상전이 현상을 적용하여 온실가스의 재생에너지를 획기적으로 낮출 수 있는 공정에 대한 전산모사를 수행하였다. MEA 30 wt% 수용액에 온실가스인 이산화탄소를 용해시키면 이산화탄소의 mole loading 정도에 따라 두 상으로 상분리가 일어나는데 이 현상을 적용하면 본래의 흡수탑-탈거탑으로 구성된 공정에서보다 재생에너지를 약 61% 가량을 낮출 수 있다.

In this study, simulation works for a carbon dioxide capture process using solvent absorption method have been performed for decrease of regeneration energy in applying phase transition of liquid solvent. When carbon dioxide is dissolved in 30 wt% MEA solvent, liquid mixture divided into two phase according to mole loading of dissolved carbon dioxide. Using this phenomenon, we can decrease regeneration energy about 61% than primary absorber column-stripper column process.
