It is necessary in many process industries to purify gas streams by removing solid or liquid impurities. Oil-mist filters can be divided into two main groups, namely oleophilic (wettable) and oleophobic (non-wettable). In this study, the relationship between wet (multi-phase) pressure drop, saturation and filter face velocity in mist (or coalescing) filters were investigated. Three different types of oleophobic filters (fibrous, knitted and open-cell foam) were studied over a wide range of inlet velocities (0.05 to 2 m/s) using Computational Fluid Dynamics (CFD). The volume of fluid (VOF) solver in OpenFoam was used to calculate pressure drop across the filter and transport of the captured oil through the filter.

Experiments were conducted to verify the simulations. It is found that...
