Optimization of Multi Cylindrical Filters for Industrial Gas Processing Plants

Gas filters utilize multi cylindrical filter tubes to capture undesirable solids and remove them from a gas stream. An optimization effort described in this paper starts with commonly used multi cylindrical filters and aims at significantly decreasing the gas pressure drop across the gas filter resulting in possible reduction in the diameter of the vessel while maintaining acceptable pressure loss. Computational fluid dynamics (CFD) modeling is used to determine the effects of filter tube diameter and multi filter tube packing on the overall pressure drop across the vessel.
