Optimization of vane mist eliminators

Vane mist eliminators are among the most effective devices to separate liquid droplets from a gas flow. Separation efficiency of these devices is largely dependent on the gas velocity, vane spacing and vane turning angles. In this study the efficiency of this type of mist eliminator has been investigated, using computational fluid dynamic (CFD). In addition, a prediction model of the separation efficiency was obtained based on the response surface methodology. The simulation results showed that there was a conceivable dependency of separation efficiency on the gas velocity and geometrical parameters of vanes. The optimal values of these parameters were determined in order to achieve the maximum separation efficiency.
