Edible Oil Refining
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; for these reasons, all the oil has to be refined. Steps Degumming Vegetable oil contains lecithins, phospholipids, and metals, which are generally called, because of their appearance, ''mucilaginous gums'' or simply ''gum''. The process of elimination of the gums is called degumming. These gums are natural emulsifiers, that can cause an increase in viscosity which is an important parameter for the final product. Because of this physical problem, it is important to perform this first step since the high viscosity could create difficulties during the subsequent filtration steps. Depending on the raw oil, these substances are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petroleum Product
Petroleum products are materials derived from crude oil (petroleum) 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. Most petroleum is converted into petroleum products, which include several classes of fuels. According to the composition of the crude oil and depending on the demands of the market, refineries can produce different shares of petroleum products. The largest share of oil products is used as "energy carriers", i.e. various grades of fuel oil and gasoline. These fuels include or can be blended to give gasoline, jet fuel, diesel fuel, heating oil, and heavier fuel oils. Heavier (less volatile) fractions can also be used to produce asphalt, tar, paraffin wax, lubricating and other heavy oils. Refineries also produce other chemicals, some of which are used in chemical processes to produce plastics and other useful materials. Since petrole ...
