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 napthenic in nature depending on the chemical structure of the molecules.

Base oils are used to manufacture products including lubricating greases, motor oil and metal processing fluids. Different products require different compositions and properties in the oil. One of the most important factors is the liquid’s viscosity at various temperatures. Whether or not a crude oil is suitable to be made into a base oil is determined by the concentration of base oil molecules as well as how easily these can be extracted.

TIBA PETROCHEMICAL COMPANY DMCC is an integrated international oil and gas company in Dubai, UAE with a wide range of network around the world. Tibapetro is marketing Base oil and they are the international leader in the Oil, Gas and Petrochemical industry, with a long-term vision and to contribute to Dubai’s ever growing economy.

Base Oil Advantages
Group II Base Oils have lower sulfur and higher saturates compared to Group I Base Oils. This results in base stocks that are superior for blending stable high-performance finished lubricants. Group III Base Oils compared to Group I and Group II Base Oils have higher viscosity index, lighter color, and better low temperature properties. They are technically comparable to alternate synthetic base oils without the associated higher cost.

End Uses
Suitable for formulating premium engine oils, gear oil, hydraulic oils and greases. Used in agriculture and as detergents/dispersants.

Classification
According to the American Petroleum Institute (API), base oils fall into five main groups. This breakdown is based on the refining method and the base oil’s properties in terms of, among other things, viscosity and the proportion of saturates and sulfur content.

Group I
The least refined type which produced by Solvent Refining. It usually consists of conventional petroleum base oils.

API defines group I as “base stocks contain less than 90 percent saturates and/or greater than 0.03 percent sulfur and have a viscosity index greater than or equal to 80 and less than 120”.

Group II
Better grade of petroleum base oil, which may be partially produced by Hyrocracking.

API defines group II as “base stocks contain greater than or equal to 90 percent saturates and less than or equal to 0.03 percent sulfur and have a viscosity index greater than or equal to 80 and less than 120”.

Group III
The best grade of petroleum base oil, since they are fully produced by Hyrocracking, which make these oils purer.

API defines group III as “base stocks contain greater than or equal to 90 percent saturates and less than or equal to 0.03 percent sulfur and have a viscosity index greater than or equal to 120”.

This group may be described as Synthetic Technology oils or Hydro-Cracked Synthetic oil. However, some oil companies may call their products under this group as synthetic oil.

Group IV
Consists of synthetic oils made of Poly-alpha-olfiens PAO.

Poly-alpha-olfiens PAO oils are much more stable in extreme temperatures, which make much more suitable for use in very cold weather (as found in northern Europe) as well as very hot weather (as in Middle East).

Group V
Any type of base oil other than mentioned in the previously defined groups.

They include, among others, naphthenic oils and esters.
