Lubricants usually become unsuitable for continued use due to the accumulation of contaminants, including combustion byproducts, oxidation residues, and remnants of degraded additives.
Our recycling process resolves these issues by removing accumulated contaminants and restoring the oil to its original state, creating chemically and physically indistinguishable base oil.
«Caspian Lubricants Recycling» has implemented an advanced re-refining technology that consists of three key purification stages:
During the first stage, dehydrated used oil undergoes atmospheric distillation to remove dissolved hydrocarbons of diesel and gasoline fuels. This process is entirely waste-free: the separated water is repurposed as technical cooling water, while the recovered diesel fractions are prepared for further use.
At the second stage, the purified oil is then subjected to vacuum distillation at high temperatures. Thin-film evaporators enable the precise separation of oil distillates, while components not required for further production are removed.
This stage is performed under deep vacuum conditions at temperatures exceeding 300°C. To ensure environmentally safe emissions, gases released from the vacuum system undergo a two-stage purification process – with an alkaline scrubber and a thermal oxidizer.
In the final stage, the distillate is purified at 80°C through regenerative adsorption, ensuring compliance with international quality standards.
