The electrostatic process utilised in Frames Electrostatic Coalescers is a highly effective way to remove the impurities found in various distillate streams. It works by removing impurities from the distillate through the addition of an aqueous chemical reagent to the distillate stream, dispersing the reagent throughout the stream in extremely small droplets and exposing the mixture to the influence of an electric field. Once exposed to the electric field, the reagent is coalesced and separated from the distillate, taking along with it impurities that react with or dissolve in that reagent. The reagent is virtually insoluble in the oil this enables the separation of the reagent and the impurities from the oil.
