Abstract

In this study, a computer simulation work has been performed for the carbon dioxide removal process using aqueous amine solution in the GTL (Gas To Liquids) process. 30wt% DEA(diethnaol amine) aqueous solution was utilized as a carbon dioxide remvoal agent and an absorber-stripper two-columns configuration was used. Kent-Eisenburg modeling equation built-in amine specicial package was used for the modeling of the carbon dioxide removal process. PRO/II with PROVISION 9.0, a commercial process simulator was used. Through this simulation study, heat and material balance was obtained and packing column diameter and column height were also estimated.

본 연구에서는 GTL (Gas To Liquids) 파일럿 공정의 설계를 위한 아민 수용액을 이용한 이산화탄소 제거공정에 대한 전산모사를 수행하였다. 이산화탄소 제거를 위한 용매로써 30wt% DEA(diethanol amine) 수용액을 사용하였으며, 공정 배열은 흡수탑과 탈거탑의 2기의 column을 사용하였다. 전산모사를 위해서 Invensys사의 PRO/II with PROVISION 9.0을 사용하였으며 열역학 모델식으로는 amine special package내의 Kent-Eisneberg 모델식을 사용하였다. 전산모사를 통해서 이산화탄소 제거공정에 대한 열 및 물질수지를 도출하였으며, 흡수탑과 탈거탑에 대한 충진탑의 직경과 높이를 산출하였다.
