초록

이산화탄소 분리 및 메탄 회수를 동시에 수행하기 위한 배출구가 두 개로 분리된 내부순환식 기포탑 반응기를 이용하여 CO2 분리용 흡수제인 모노에탄올아민(MEA)의 최적조건을 도출하였다. 5 wt% MEA 수용액에서 이산화탄소의 흡수 및 탈기 반응 시 pH 변화, 공기주입량에 따른 이산화탄소 탈기량 및 메탄 함량변화를 관찰하였다. 또한 액상수위 및 초기 MEA 흡수액 온도변화에 따른 이산화탄소 흡수 및 메탄 회수율을 측정하였다. 최적반응조건은 정상상태에서 액상수위 40 mm, 공기주입량은 1.5 L/min, 흡수액의 온도 25 ℃이었다.

For the simultaneous methane recovery and CO2-stripping, we have been developed dual vent auto circulation bubble lift column reactor, and evaluate optimum conditions for monoethanolamine (MEA) solutions as a CO2 absorbent. At the 5 wt% MEA solution, we investigated the pH change during CO2-stripping and absorption reaction, CO2-stripping rate with reaction time, methane recovery efficiency for various inflow rates of air, CO2-stripping rate for flow liquid over flow height, and CO2-stripping dependency on the temperature of absolvent solutions. The suggested optimum conditions for CO2 recovery with MEA in the dual vent auto circulation bubble lift column reactor were 40 mm over flow liquid height, 1.5 L/min of air inflow rate, and 25 ℃ of absorbent solution temperature.
