Q8 Lubricants & Oils
Promar Industrial chemicals supplies to its customer lubricants and oils of Kuwait Petroleum International, known by the Q8 brand, which refines and markets fuel, lubricants and other petroleum derivatives to mainyl Europe and the Far East.
Q8 Lubricants and Oils are not just for the use at car engines. There are many different types including metalworking fluids, transformer oils, gear and hydraulic oils.
Fluid oils and greases, both solid and semi solid, are also used for lubrication, too.
There are three groups of lubricant base oils:
• mineral based oils that originate from crude oil;
• synthetic based oils from synthesised components;
• semi-synthetic base oils, which provide many of the advantages of synthetic oils.
Additives are blended with base oils and the combination, quality and quantity of the additives and base oils determine the quality and the properties of the finished lubricant.
Mineral oil is made by distilling and refining crude oil. Its properties depend largely on the quality and consistency of the crude oil from which it is refined and on the refining process itself.
Mineral base oil is a blend of refined distillation fractions that result from vacuum distillation. It consists of hydrocarbons and traces of sulphur, oxygen and nitrogen containing hydrocarbons. The distillation fraction is further purified by extraction and by separating the waxes.
The purification process can be completed with hydro-finishing, which involves contact with hydrogen at a high pressure and temperature, in the presence of a catalyst.
The properties of synthetic oil are determined entirely by its manufacturing process.
Synthetic oils are free of impurities and generally have a higher viscosity and better oxidation stability than mineral base oils, resulting in a better and longer lasting performance.
Semi-synthetic oils are blended from a combination of mineral and synthetic base oils, which provide some of the benefits of synthetic oil.
