RE-REFINING

PRE-TREATMENT

Used Oil is heated and treated with chemicals to separate suspended solids and water content in preparation for the Distillation process.

DISTILLATION

Wren Oil utilises Vacuum Distillation re-refining technology to remove heavy metals, contaminants and ash content from used oil, to recover re-refined oils and other petroleum fractions.

SOLVENT EXTRACTION

After the Distillation process the re-refined lubricant is further processed with a solvent that extracts the final stages of impurities and aromatic compounds from the oil, resulting in clean, high quality specification Base Oil products
