주류공정 내 L-alanine‧염 스크러버를 이용한 고농도 이산화탄소 저감 효율 평가

This study evaluated CO2 removal efficiency, monitoring data analysis / evaluation efficiency and energy reduction efficiency in the liquor factory by L-alanine applied scrubber. The average removal rate of the scrubber was 90.45%, and it was confirmed that the removal efficiency was excellent above 10,000ppm of inlet CO2 concentration. After the scrubber operation, the CO2 concentration in the workplace was maintained under 2,000ppm(the carbon dioxide reduction efficiency was about 74%). and the energy saving efficiency was calculated to 7.26% by reducing the power consumption. As a result of applying the developed product, it was possible to improve the working environment of workers by reducing the carbon dioxide concentration in the workplace at low concentration without ventilation, and to reduce the energy consumption. Therefore, it is expected that the scrubber will be useful as a high CO2 removal process in food and liquor factories.
