Base oil is a type of oil which is used as a base for lubricants. The main element of lubricants (volume wise) is base oil and it forms about 95% of lubricants weight. In some lubricants (Compressor and hydraulic oil) 99% of the oil is consisted of base oil and only the 1% which is left contains additives. Base oils can be reached from oil based and non-oil based resources. Most of the base oils used in the world are obtained from crude oil refining. Most of the compounds which form base oils are Paraphinic, Naphthenic and aromatic compounds.
Base oils chemical properties and their impact on the usage of final lubricant:
1 volatility: reduction of the oil, oil thickening, sediments
2 surface activity: foaming, pressure tolerance, air release, emulsion expansion
3 oxidations: sediments, oil thickening, metal oxidation, mud forming
4 Viscosity: Fluidity in lower degrees, energy waste, abrasion protection, proper cooling
5 being soluble: Motor neatness, sealant compatibility, process applications, formulation sustainability The base oil which is extracted from crude oil is called mineral base oil which is categorized in two types (Paraphinic and Naphtshic). Paraphinic oils are consisted of normal hydrocarbons and Iso hydrocarbons. Naphthic oils are consisted of annular full hydrocarbons. Paraphinic oils have certain attributes in comparison with naphthic oils such as;
Bitumen is known for its waterproofing and adhesive properties and is commonly used in the construction industry, notably for roads and highways. Production occurs through distillation, which removes lighter crude oil components like gasoline and diesel, leaving the heavier bitumen behind.
Bitumen deposits can also occur naturally at the bottom of ancient lakes, where prehistoric organisms have decayed and been subjected to heat and pressure.
