Oil purification cleans oil from contaminants. It can be used independently or as a part of oil regeneration. Oil regeneration also removes aging products (with the help of adsorbents) and stabilizes oil with additives. Regenerated oil is clean from carcinogenic products of oil aging and stabilized with the help of additives.
Refining is used primarily in the petroleum industry, whereby crude oil is heated and separated into stages according to the condensation points of the various elements. Distillation, widely used in petroleum refining and in purification of ethanol separates volatile liquids on the basis of their relative volatilities. There are several type of ...
Oil filtration refers to the method of purifying oil by removing impurities that can degrade its quality. Contaminants can enter the oil through various means, including wear and tear of machinery components, environmental factors, and improper handling during oil changes.
Molecular distillation is used industrially for purification of oils. [ 4 ] [ 5 ] It is also used to enrich borage oil in γ-linolenic acid (GLA) and also to recover tocopherols from deodorizer distillate of soybean oil (DDSO). [ 2 ]
Fractionation is also used for culinary purposes, as coconut oil, palm oil, and palm kernel oil are fractionated to produce oils of different viscosities, that may be used for different purposes. These oils typically use fractional crystallization (separation by solubility at temperatures) for the separation process instead of distillation.
A natural-gas processing plant in Aderklaa, Austria. Natural-gas processing is a range of industrial processes designed to purify raw natural gas by removing contaminants such as solids, water, carbon dioxide (CO 2), hydrogen sulfide (H 2 S), mercury and higher molecular mass hydrocarbons to produce pipeline quality dry natural gas [1] for pipeline distribution and final use.

Edible oil refining is a set of processes or treatments necessary to turn vegetable raw oil into edible oil.. Raw vegetable oil, obtained from seeds by pressing, solvent extraction, contains free fatty acids and other components such as phospholipids, waxes, peroxides, aldehydes, and ketones, which contribute to undesirable flavor, odor, and appearance; [1] for these reasons, all the oil has ...
