Base Oil, Processing Type : Virgin

Base Oil is the name given to lubrication grade oils initially produced from refining crude oil (mineral base oil) or through chemical synthesis (synthetic base oil). Base oil is typically defined as oil with a boiling point range between 550 and 1050 F, consisting of hydrocarbons with 18 to 40 carbon atoms. This oil can be either paraffinic or naphthenic in nature depending on the chemical structure of the molecules.
The quality of base oils is determined by their olefinic, nitrogenated and sulfured compound contents. This is determined by the refining process which it undergoes in its cleaning and removing of impurities. In order to meet composition specifications, these oils are submitted to the hydro-treatment (HDT) process before addition of other compounds for commercial production. This process is characterized by the use of operational conditions of low or medium severity so that aromatic distribution is not seriously affected and sulfur compounds are not completely removed.
Base oils are generally fully saturated and extremely pure, with very low volatility and high viscosity index. The proportions of different hydrocarbon components determine the characteristics of the base oils. Viscosity is a measure of the base oil’s ability to not thicken at low temperatures and not thin out at high temperatures.
Base oils may be refined, re-refined, recycled, or reusable. Base oils are produced using an advanced hydro cracking and hydro isomerization process.
