Gas impurities and gaseous heavy hydrocarbons will not interfere with the GasDry dehydration process, so long as these impurities are in the vapor state. Liquid droplets of any substance cannot enter the gas dryer vessel without negatively affecting the performance of the system. This includes liquid water, hydrocarbon condensate, and lubricants. If liquids are present in upstream gas a separator and/or coalescing filter must be installed ahead of the desiccant gas dryer.
