에너지 절약형 Tray Type FGD Absorber의 수치해석적 연구

This study is performed to understand the effect of the tray in the absorber of a flue gas desulphurization (FGD) system using computational fluid dynamic (CFD) technique. The contact area, the stagnant time and the gas distribution improvement between the flue gas and slurry increase due to the tray in the absorber. The increased area and time raise the desulphurization effect and reduce power of the absorber recirculation pump. The gas and slurry hydrodynamics inside the absorber is simulated using a commercial CFD code. The continuous gas phase has been modeled in an Eulerian framework, while the dispersed liquid phase with a Lagrangian approach by tracking a large number of particles through the computational domain.
