연도주입식 배가스 탈황기술은 배가스를 가습 하고 가습된 배가스가 흐르는 덕트로 소석회 와 같은 흡수제를 주입하여 SO2를 제거하는 건식탈황기술이다[1]. 연도주입식 배가스 탈황 공정에서 흡수제와 SO2 사이의 반응은 덕트에 서 1차 반응이 일어나고 집진장치에서 포집된 미반응 흡수제에 의하여 추가반응이 일어난다
The effects of the temperature and approach to adiabatic saturation temperature of simulated flue gas on the performance of a duct injection flue gas desulfurization process were investigated using a pilot scale reaction system with Ca(OH)2 as the sorbent. The results of experiments showed that the SO2 removal efficiency and sorbent conversion were better at higher temperature or at lower approach to adiabatic saturation temperature because more water is adsorbed on the surface of sorbent. As the Ca/S mole ratio was increased, SO2 removal efficiency increased and sorbent conversion decreased. The increase of SO2 removal efficiency with increasing Ca/S mole ratio was greater at lower approach to adiabatic saturation temperature.
