BASE OIL
Base oils are used to manufacture products including lubricating greases, motor oil and metal working fluids. Different products require different compositions and properties in the oil. We can provide all of the following: Base Stocks, Brightstock, Naphthenic, Paraffinic, Processoil, Refrigeration Oils, Transformer Oils, Compressor Oils, Synthetic Base Oils.
Base oil is produced by means of refining crude oil. This means that the crude oil is heated so that various distillates can be separated from one another. During the heating process, light and heavy hydrocarbons are split. Then, the light ones can be refined to make petrol and some other fuels, while the heavier ones are suitable for tar and base oils.
Crude Oil
There are large numbers of crude oils all around the world that are used to produce base oils. The most common one is a type of paraffinic crude oil. There are also naphthenic crude oils that create products with better solubility and very good properties at low temperatures. By using hydro technology, the sulfur and aromatics are removed using water under high pressure.
Chemical substances or additives are mixed in with the base oil to meet the quality requirements for the end products. Certain types of motor oils could contain more than twenty percent of additives.
Base Oil Groups
Group 1 – This is the least refined type of oil which is produced by Solvent Refining. It usually consists of conventional base oils.
Group 2 – Better grade of petrol base oil, which may be partially produced by Hydrocracking.
Group 3 – The best grade of petroleum base oil. Since they are fully produced by hydrocracking, these oils are more pure.
Group 4 – Consists of synthetic oils made of Poly-alpha-olefins or PAO.
Poly-alpha-olefins PAO oils are much more stable in extreme temperatures, which make much more suitable for use in very cold and very hot weathers.
Group 5 – Any type of base oil other than mentioned in the previously defined groups. They include, among others, naphthenic oils and esters
Base Oil Viscosity Chart
Base Oil Group 1 & Group 2 Viscosity Index Rang From 80 To 120 Within 132 To 150 Temperature.
Group 3 Viscosity Index Is Higher That 120 That Are Hydro-Cracked Within High Pressure & Heat.
Group 1 VI: 80-120 Temp: 132-150
Group 2 VI: 80-120 Temp: 132-150
Group 3 >120 Higher Pressures And Temperatures
How Base Oil Is Produced
Base Oil Is Produced By Refining Procedure:
Heating —-> Separating Distillates —> Refining Heavier Hydrocarbons —> De-Waxing —> Removing Sulfur & Aromatics —> Solvent Extraction —> Adding Additives —> Hydro-Treating
