초록

SEWGS 공정에 사용하기 위해 개발된 두 종류의 $CO_2$ 흡수제(PKM1-SU, P4-600)에 대해 가압 회분식 유동층 반응기를 사용하여 각 흡수제의 반응성에 미치는 조업변수의 영향을 측정 및 해석하였다. PKM1-SU 입자와 P4-600 입자 모두 흡수-재생 반복횟수가 증가함에 따라 흡수능이 감소하는 경향을 나타내었으며 $CO_2$ 흡수능력 측면에서는 PKM1-SU 입자가 우수한 성능을 나타내었으나 재생반응온도와 재생반응속도 측면에서는 P4-600 입자가 우수한 것으로 나타났다. PKM1-SU 입자는 스팀농도가 증가함에 따라 $CO_2$ 흡수능이 증가하였으나 P4-600 입자의 경우 스팀농도 5%에서 10%로 증가함에 따라 $CO_2$ 흡수능이 증가한 후 거의 일정한 경향을 나타내었다. 두 흡수제 모두 최종 재생온도가 증가함에 따라 $CO_2$ 흡수능이 증가하는 경향을 나타내었으며 PKM1-SU 입자의 경우 15 bar 이상에서는 압력이 증가함에 따라 $CO_2$ 흡수능력이 급격히 증가하는 경향을 나타내었다.

The Effects of operating variables on reactivity of two $CO_2$ absorbents (PKM1-SU and P4-600) for SEWGS process were investigated in a pressurized fluidized bed reactor. For both $CO_2$ absorbents, $CO_2$ sorption capacity decreased as the number of absorption-regeneration cycles increased. PKM1-SU absorbent represented higher $CO_2$ sorption capacity than that of P4-600 absorbent. However, P4-600 absorbent represented better performance than PKM1-SU absorbent from the view points of regeneration temperature and regeneration rate. For PKM1-SU absorbent, $CO_2$ sorption capacity increased as the steam concentration increased. However, $CO_2$ sorption capacity increased initially as the steam concentration increased from 5% to 10%, but maintained thereafter for P4-600 absorbent. For both $CO_2$ absorbents, $CO_2$ sorption capacity increased as the final regeneration temperature increased. For PKM1-SU absorbent, $CO_2$ sorption capacity increased as the pressure increased and the increment tendency was drastic at higher pressure than 15 bar.
