Lubricating oils are a combination of base oils and additives. The main functions of lubricating oils include:
Reducing friction
Dissipating heat
Keeping contaminants suspended
The re-refining process restores the oil to its original state as base oil. This process recovers 99% of the composition of lubricating oil from waste materials, creating an almost permanent cycle of reuse from a limited and diminishing resource.
The re-refining process removes all contaminants and returns the oil to its original state. Contaminants such as dirt, water, fuel, and used additives are eliminated through vacuum distillation. The oil is then further refined to remove any remaining chemicals, ensuring that the oil’s quality meets international standards. After re-refining, the lubricating oils are sold to third parties to be blended with additives for the production of motor oils, hydraulic oils, gear oils, refrigeration oils, vacuum pump oils, and more.
