Production line and factory setup overview
A licensed small/medium hazardous-waste re-refining plant converting source-segregated used lubricating oil into tested base-oil fractions through manifest receipt, quarantine sampling, settling and coarse filtration, dehydration and light-end removal, high-vacuum thin-film or molecular distillation, fraction condensation, residue removal, optional polishing, base-oil laboratory release, closed storage and controlled loading. Simple filtration does not restore spent engine oil and is not presented as re-refining.
Recommended lowest-entry line configuration Proceed only after hazardous-waste and air-emission permits, feedstock collection contracts, residue disposal route and a bankable laboratory trial. The smallest responsible basis is roughly 5-10 t/day with closed pretreatment, high-vacuum distillation, condensers, non-condensable-gas treatment, residue handling, firefighting, wastewater control and a full lubricant/base-oil laboratory. Do not bottle the output as engine oil without separate blending and performance approval.
Production process and implementation sequence
- Manifest receipt, quarantine and feed analysis
- Settling, coarse filtration and dewatering
- Dehydration and light-end stripping
- High-vacuum thin-film/molecular distillation
- Fraction condensation and closed collection
- Residue and non-condensable-gas treatment
- Base-oil laboratory release
- Closed tank storage and controlled dispatch
Products, capacity and market fit
- Used lubricating oil is locally generated and often mishandled.
- Proper re-refining can recover base-oil fractions while controlling hazardous residues.
- A licensed collection system supports traceability and stable feed quality.
- Vacuum integrity, emissions, residue disposal and laboratory release make this an industrial—not workshop—project.
- Re-refined base-oil fraction - Boiling/viscosity cut, viscosity index, flash/pour point, water, sulfur, metals, acidity, colour and carbon residue - Licensed lubricant blenders after formula and performance qualification
