Abstract: A process for the quality improvement of a nonpetroleum organic liquid (fats, animal and vegetable oils) containing color bodies, moisture and alkali soaps as impurities. The organic liquid is subjected to (1) a refining step using an aqueous alkali reagent, (2) admixing with the organic liquid of a finely dispersed solid adsorbent, (3) elevated temperatures dehydrating and deareating the mixture of the organic liquid and dispersed solid adsorbent, and (4) electrofiltration of the mixture of organic liquid and solid adsorbent to provide a solids-free, soaps-free quality improved organic liquid which is passed to a subsequent utilization (e.g., hydrogenation, deodorization, etc.). Electrofiltration is conducted in an atmosphere substantially devoid of oxygen-containing gases and moisture.
