Determination the Factors Affecting the Vane-Plate Demisters Efficiency Using CFD Modeling

Vane-plate demisters (VPD) or wave-plate mist eliminators are a kind of liquid eliminator equipments used to remove the liquid with 10-100 μm droplet diameter from the gas. In this paper we determine the factors affecting the vane-plate mist eliminator efficiency using Computational Fluid Dynamics (CFD). The simulation results were compared with the experimental results of Jia et al. [1]. The work considers three factors 1. Flow speed 2. Plates distance 3. Hook existence After comparing the parameters effects. It was proved that, the higher velocity the more efficiency but meanwhile more re-entrainment occurrence that is not desired and the closer the plates, the better. It was shown that the best way to gain 100% removing is hook existence.
