초록

본 연구에서는 주류공장 내 고농도 CO2 제거 및 포집을 위해 L-alanine 흡수제를 적용하여 CO2 흡수, 탈리 효율을 평가 후 재생 성능을 확인하였다. 탈리공정의 효율적인 처리를 평가하기 위해 실험 실 규모에서 Hot plate, Steam 두가지 탈리 방법을 비교하였으며 Hot plate는 약 10%, Steam의 경우 약 60%의 재생효율을 확인하였다. 따라서 주류공장 내 100m3/min 실증화 규모에 Steam-Tower 탈리공정을 적용하여 최적조건을 평가한 결과 탈리 유량 4L/min 이하, Steam 온도 160℃ 이상, 탈리효율 85.5%로 확 인할 수 있었다.
In this study, amino acid salt absorbents were applied to remove and capture high concentrations of CO2 in liquor factories and regeneration performance was confirmed. In order to evaluate the effective treatment of the desorption process, two methods(Hot plate and Steam) were compared at the laboratory scale. As a result, hot plate and Steam. Hot plate methods regeneration efficiency was about 10% and Steam methods was about 60%. The Steam-Tower condition was evaluated by installing a 100m3/min flow rate scrubber absorption system in the liquor factory. As a result, it was established that the absorbent flow rate was below 4L/min and the steam temperature was above 160℃. Finally regeneration performance was confirmed as 85.5%.
