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 ...
Petroleum oil refinery, which converts crude oil into high-octane motor spirit (gasoline/petrol), diesel oil, liquefied petroleum gases (LPG), kerosene, heating fuel oils, hexane, lubricating oils, bitumen, and petroleum coke; Edible oil refinery which converts cooking oil into a product that is uniform in taste, smell and appearance, and stability
The K factor or characterization factor is defined from Rankine boiling temperature °R=1.8Tb[k] and relative to water density ρ at 60°F: . K(UOP) = / The K factor is a systematic way of classifying a crude oil according to its paraffinic, naphthenic, intermediate or aromatic nature. 12.5 or higher indicate a crude oil of predominantly paraffinic constituents, while 10 or lower indicate a ...
Vegetable oil refining may refer to: Fat hydrogenation, combining vegetable oil with hydrogen to make it more saturated; Edible oil refining, process to refin a raw oil to produce an edible oil, which differ from Olive oil production. Biodiesel production by transesterification; Production of hydrotreated vegetable oil, a biofuel
In the processing of edible oils, the oil is heated under vacuum to near the smoke point or to about 232 °C (450 °F), [33] and water is introduced at the bottom of the oil. The water immediately is converted to steam, which bubbles through the oil, carrying with it any chemicals which are water-soluble.

A petrochemical refinery in Grangemouth, Scotland . Petroleum products are materials derived from crude oil as it is processed in oil refineries.Unlike petrochemicals, which are a collection of well-defined usually pure organic compounds, petroleum products are complex mixtures. [1]
For edible oils, the tolerated limit of unsaponifiable matter is 1.5% (olive, refined soybean), while inferior quality crude or pomace oil could reach 3%. [ 12 ] [ 13 ] Determination of unsaponifiables involves a saponification step of the sample followed by extraction of the unsaponifiable using an organic solvent (i.e. diethyl ether ).
