Countries such as the US, Brazil, China, and some other Western European countries where production of biomass and coal is high can create additional ecologic fuels and specialty product (lube oils, waxes, and olefins) capacities at low in GTL is on producing high-quality middle distillate fuels and naphtha for petrochemical uses, it has also gained interest due to its ability to generate high-quality specialty products, including lubricant base oil, waxes, and olefins. Paraffinic hydrocarbons are the best lubricants. High-gravity crude oils contain more of the lighter The most common separation process is distillation, where the components of the crude are separated into several streams based on their boiling temperature. SAE viscosity index >120 - Manufactured by special processes such as isohydromerization. The distillation process in the refinery separates the hydrocarbons contained in the crude into cuts based on the molecule size. Slide13: Liquid lubricants Lanolin (wool grease, natural water repellant) Water Mineral oils Vegetable (natural oil) Synthetic oils Others Note: although generally lubricants are based on one type of base oil or another, it is quite possible to use mixtures of the base oils to meet performance requirements. Can be manufactured from base oil or slax wax from dewaxing process. Lubricant Base Oil and Wax Processing. They are cost-effective and The presence of waxes, which can result in poor flow properties at low temperature. In other words the mineral oil production process is physical cleaning and the end product is so-called paraffinic base oil. Solvent processing, first used in the 1930s to improve base oil performance, is still used today to produce Group I lubricant stock. When choosing synthetic oil over regular mineral oil it's worth remembering that mineral oils have been around for a long time and function very well as lubricants in most industrial applications. In the refining process, the crude oil is converted into transportation fuels—gasoline, jet fuel, and diesel fuel—and other petroleum products, such as liquefied petroleum gas (LPG), heating fuel, lubricating oil, wax, and asphalt. Poor oxidation stability at Synthetic base oils are expensive because of the processing involved in creating these pure chemical base oils. Furthermore, as many unwanted substances as possible are removed in the process, such as sulphur, aromatic hydrocarbons, paraffin wax, etc. Titolo:Lubricant Base Oil and Wax Processing Autori:Avilino Sequeira Anno pubbl.:1994.
