ABSTRACT:
Non-petroleum organic liquids (fats, animal and vegetable oils, etc.) containing solids (e.g., hydrogenation catalysts) are purified within a unique electrofiltration system wherein the organic liquids are passed through a selected bed material in which is established an intense electric field for removing the solids. Upon solids-fillup of the bed, selectively cleaning restores the bed for continued purification of the organic liquid stream. The purified organic liquid stream is monitored for indicating when the selective cleaning of the bed is required. The electrofiltration system, both in a novel electrofilter and process, produces without aging a new organic liquid product having comparable properties to multistep processed prior art organic liquid.
