초록

Flaring gas에서 $CO_2$ 제거를 위해 폴리술폰 고분자를 이용한 중공사막을 제조하였다. 제조된 중공사막은 1단과 2단 공정의 전산모사와 실제 공정을 통해서 $CH_4$ 농도 99% 이상 $CO_2$ 농도 1% 미만의 운전조건과 성능을 확인하였다. 또한 $25Nm^3/h$ 급 bench scale $CO_2$ 분리막 연속공정에서 100시간의 운전시간 동안 $CO_2$의 농도를 1% 미만으로 안정적으로 운전하였고 이때의 $CH_4$ 회수율은 약 98%였다.

Polysulfone (PSF) hollow fiber membrane was prepared to separate $CO_2$ from the flaring gas. Fabricated PSF membrane system was fulfilled under 1 stage, 2 stage membrane process and simulation in order to confirm the operating condition for 99% of $CH_4$ and 1% of $CO_2$ concentration. Also, $25Nm^3/h$ bench scale $CO_2$ separation membrane system was operated under 1% of $CO_2$ concentration during 100 hr, and $CH_4$ recovery ratio was 98%.
