Base oils

Base oils are used to manufacture products including lubricating greases, motor oils, and metalworking fluids. Different products require different compounds and properties in oil. One of the most important factors is the viscosity of the liquid at different temperatures. Whether a crude oil is suitable for base oil conversion is determined by the concentration of base oil molecules and how easily they can be extracted. Base oil is produced by refining crude oil. This means that the crude oil is heated so that the various spirits can be separated from each other. During the heating process, light and heavy hydrocarbons are separated – the light type can be refined to produce gasoline and other fuels, while the heavier ones are suitable for bitumen and base oils. There are many crude oils around the world that are used to produce base oil. The most common is a paraffinic type of crude oil, although naphthenic crude oils also exist which provide products with better solubility and very good low temperature properties. Using hydrogenation technology, in which sulfur and aromatics are removed using hydrogen under high pressure, it is possible to obtain very pure base oils that are suitable when quality requirements are particularly strict. Chemicals - additives - are added to the base oil to meet the quality requirements of the final products in terms of, for example, friction and cleaning properties. Certain types of motor oil contain more than twenty percent additives. SN 150-300-500 base oil is known as a light grade base oil at the lower end of the specification for first grade light base oils. It is mostly used in the production of lubricants and lubricant additives. It is a Group I base oil that has undergone solvent refining processes. Base oils are used to produce products such as motor oil, industrial oil, grease, etc.
