Hydrorefining Edible Liquid Light Paraffin Oil Food/Cosmetic/Medical/Agricultural Grade White Mineral Oil Uni-bright BrandThe only edible light paraffin oil manufacture with hydrorefining process in Asia
White oil is a colorless, odorless and non corrosive refined light mineral oil whose aromatics, oxygen, sulfur, nitrogen and other impurities are very little. Its main ingredients are saturated hydrocarbons (cycloalkanes and alkanes). White oil has good chemical inertness, excellent light and heat stability.
Uses of white mineral oil White oil is divided into three categories: industrial white oil, cosmetic white oil and food grade white oil in China. White oil is generally divided into industrial grade and food and medicine grade in the world. The main classification indexes of all kinds of white oil are: chroma, easily carbonized substance, ultraviolet absorbance, viscosity and heavy metal content, etc. As a high value-added product, white oil is widely used in industry, cosmetics industry, food and medicine industry. Industrial white oil is mainly used in the fields of chemical fiber, aluminum processing and rubber, as well as in the lubrication of textile machinery and precision instruments and compressor sealing oil; cosmetic white oil is suitable for the raw materials of cosmetics industry, the production of hair cream, hair oil, lipstick, skin care grease, sun lotion, hand cream, etc.; food grade white oil is used for the lubrication of food processing machinery and equipment that are not in direct contact with food, including The lubrication of food industrial processing equipment, such as grain and oil processing, fruit and vegetable processing, dairy products processing, is also applicable to food polishing, anti sticking, demoulding, sealing, prolonging the storage period of wine, vinegar and can, as well as the anti-corrosion lubrication of the base oil of lubricating cathartic and ointment, demoulding agent of tablets and pills, surgical instruments and pharmaceutical instruments. Besides, emulsified food grade mineral oil can be used for insecticide agriculrural spray.
Process of white mineral oil There are three main production methods of white oil: the first one is the sulfonation method of producing white oil by using fuming sulfuric acid or sulfur trioxide as raw material; the second one is the method of producing white oil by using a small amount of fuming sulfuric acid sulfonation hydrogenation base oil; the third one is the hydrogenation method of producing white oil. 1. The disadvantages of sulfonation, such as large consumption of sulfuric acid and large discharge capacity of three wastes, are gradually replaced by hydrogenation, which has no pollution, high yield and good product quality. 2. Hydrogenation micro acid sulfonation method is to use a small amount of fuming sulfuric acid to sulfonate hydrogenation base oil to obtain high quality white oil products. Compared with the high-pressure hydrogenation process, the production of white oil by micro acid sulfonation process has low cost and investment. Compared with the traditional sulfonation process, the amount of fuming sulfuric acid is greatly reduced and the environmental pollution is small. It is available for white oil of low viscosity, but not white oil of high viscosity. 3. The main principle of white oil production by hydrogenation is to remove sulfur, nitrogen, oxygen and other heteroatoms from raw oil, saturate olefins, deeply remove aromatics, and remove impurities such as metal, asphalt and gum through high-pressure hydrogenation. The advantages of white oil production by hydrogenation are: wide source of raw materials, continuous production, high yield, good product quality, small environmental pollution, production of industrial white oil of various viscosity brands, white oil for cosmetics and food grade white oil. The main disadvantage is high investment in equipment.
According to the properties of raw materials and the number of hydrogenation stages, the hydrogenation process of white oil includes 1-stage hydrogenation, 2-stage hydrogenation and 3-stage hydrogenation. The first stage is the hydrotreating process of raw materials, the main purpose is to remove sulfur, nitrogen, oxygen and saturate some aromatics, the second stage is hydrodewaxing or isomerization dewaxing, the main purpose is to remove wax components, the third stage is hydrofining, the main purpose is to remove unsaturated aromatics in depth. In the first stage, sulfur and nitrogen resistant non noble metal catalysts are used. In the third stage, the hydrogenation is mainly a deep saturation process of aromatics, and the catalysts are usually high nickel or noble metal catalysts. 3-stage white oil hydrogenation process is more adaptable to raw materials than 2-stage white oil hydrogenation process. It can be used to produce high viscosity white oil.
