Abstract
산업 시설에서 발생하는 SO2를 제거하기 위해 중공사막 기-액 접촉기를 사용하고 있다. 본 연구에서는 기-액 접촉기 내의 중공사막에서의 SO2 흡수거동 대하여 수학적으로 모델링하고, 그 모델을 유한 요소 분석법을 이용하여 모사하였다. SO2의 분리에 영향을 주는 변수인 기체 유량, 분리막의 물질 전달 계수 및 접촉기의 물리적 특성에 따른 SO2의 분리 효율 및 물질 전달 특성을 알아보았다. 기체의 유속 변화에 따른 중공사막을 통한 SO2 제거 효율 실험값으로부터 분리막의 물질 전달 계수를 추정하였다. 또한 중공사막 설계에 도움이 되는 자료를 계산할 수 있는 방법을 제시하였다.
Hollow fiber membrane G-L contactors are widely used to remove SO2 emitted from industrial facilities. In this work, the mathematical modeling and computer simulation for hollow membrane G-L contactors is carried out to analyze SO2 absorption behavior in hollow fiber membranes. The model is solved with the finite element method using a commercial software. Investigated is the dependency of SO2 removal efficiency and mass transfer characteristics on gas velocities, membrane mass transfer coefficients and physical properties of contactors. The membrane mass transfer coefficients are estimated by fitting the experimental data with the simulated SO2 removal efficiencies. In addition, a design methodology of membrane contactors is suggested.
