  • Physical and Chemical Process in Palm Oil Refining Plant

    During the crude oil chemical refining process, the FFA will be removed and the neutralized crude oil and soap stock will be produced. And the soap stock will be separated from oil by using of high-speed separator. And the color pigments and the metal ions will be removed from the neutralized oil. If the crude oil contains high carotene, high FFA (more than 5% ) and relative low phosphatides ...

  • Chemical Refining and Physical Refining of Vegetable Oil

    Apart from chemical refining, physical refining is another method that used for edible oil refining. Through this method, the free fatty acids are removed during the process of distillation, which is one stage of deodorizing. The crude oil should be thoroughly degummed to come up with effective results. This is not applicable to some oil such as cottonseed oil. With the help of various ...

  • Alkali Refining - American Oil Chemists' Society

    The process steps in chemical refining can be adapted in accordance with the crude oil quality to give a good final oil quality with acceptable oil losses. 2. Reaction. Alkaline neutralisation involves the reaction of free fatty acids with an alkaline solution. In the edible oil industry almost only caustic soda is used for this reaction, but potassium hydroxide is also used by a few producers ...

  • Chemical Processing - How Oil Refining Works

    The major unification process is called catalytic reforming and uses a catalyst (platinum, platinum-rhenium mix) to combine low weight naphtha into aromatics, which are used in making chemicals and in blending gasoline. A significant by-product of this reaction is hydrogen gas, which is then either used for hydrocracking or sold.

  • Refining - Crown Iron Works

    Chemical refining removes the FFA in the neutralizing process while physical refining removes the FFA in the deodorizing process. Chemical refining removes the phosphatides (gums) in either two steps—degumming and neutralizing—or in a single process—neutralizing. Crown’s MaxEfficiency continuous deodorizing system exemplifies our legacy of providing the best, most reliable and ...

  • The Refining Process - How Oil Refining Works

    Newer techniques use Chemical processing on some of the fractions to make others, in a process called conversion. Chemical processing, for example, can break longer chains into shorter ones. This allows a refinery to turn diesel fuel into gasoline depending on the demand for gasoline. Refineries must treat the fractions to remove impurities.

    An oil refinery or petroleum refinery is an industrial process plant where crude oil is transformed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, liquefied petroleum gas, jet fuel and fuel oils. Petrochemicals feed stock like ethylene and propylene can also be produced directly by cracking crude oil without the need of using refined products of crude oil such as naphtha.
