Re-Refined Base Oil — General Overview

Re-refined base oil is obtained by recycling used engine oil, industrial lubricants and other suitable waste oils. The process typically involves dehydration, removal of light fractions, vacuum distillation and further treatment to improve quality. Properly processed oil can be reused in lubricant manufacturing, reducing waste and dependence on virgin petroleum resources.

Dehydration & Pre-filtration

Removal of aqueous moisture, dissolved condensates, and suspended coarse particulates from inbound feedstock via multi-stage settling and heat conditioning.

Moisture Reduction < 0.05%

Removal of Volatile Light Fractions

Thermal stripping isolates combustible fuel dilutions, residual solvents, and odorous light hydrocarbon ends, elevating ignition stability.

Flash Point Elevation Zone

High-Vacuum Distillation

Low-pressure fractional separation segregates narrow boiling ranges into targeted viscosity cuts while eliminating heavy asphaltic residue.

Vacuum Range: 0.1 - 2.0 mbar

Solvent Finishing / Polishing

Hydrofinishing or adsorption clay polishing brightens color indices, extracts aromatic precursors, and eliminates trace sulfur compounds.
