Solution Highlights
This waste lubricant re-refining solution is designed to recover valuable base oil products with high clarity, stable viscosity performance and lower sulfur content through a multi-stage upgrading route.
Advanced Process Combination
Pretreatment, thin-film evaporation, fractional distillation and solvent extraction work together to improve base oil purity and appearance.
Premium Product Upgrading
The final refining route helps achieve brighter base oil, low sulfur content, better color and improved commercial value.
Standard Process Flow
Main route: Pretreatment → Thin-Film Evaporation → Fractional Distillation → Refining by Solvent Extraction / Adsorption.
Pretreatment
Remove water, sludge and impurities to stabilize feed quality before evaporation and fractionation.
Thin-Film Evaporation
Rapid surface evaporation under vacuum reduces oxidation and protects useful oil properties.
Fractional Distillation
Separate target fractions precisely, including SN150, SN350 and SN500 base oil ranges.
Refining
Use solvent extraction or adsorption to improve clarity, reduce sulfur and enhance final product quality.

Project Example
A real project example helps demonstrate actual output quality, yield performance and engineering feasibility.
30 T/day Waste Oil Re-Refining Plant – Poland
A European client adopted VBOLT’s waste oil to base oil system integrating thin-film distillation and solvent extraction. The project achieved 95% oil yield, color 1.0 and flash point above 220°C, fully meeting EU environmental standards.
This case demonstrates the process stability and commercial value of combining vacuum thin-film evaporation, fractional distillation and advanced refining in one integrated plant solution.
Frequently Asked Questions
These are common questions from customers planning waste oil to base oil re-refining projects.
Yes. Through pretreatment, thin-film distillation, fractional distillation and refining, used lubricating oil can be upgraded into regenerated base oil with improved clarity, viscosity stability and lower sulfur content.
Thin-film distillation provides rapid surface evaporation under vacuum, reducing oxidation and thermal damage while preserving useful oil properties and improving product brightness.
The fractional distillation section can be designed for precise split of SN150, SN350 and SN500 fractions according to process requirements and target product planning.
The solution can include solvent extraction refining, adsorption refining, or a combined route depending on target base oil quality, sulfur reduction requirement and project economics.
Yes. Capacity, automation level, process modules, utility system and plant layout can all be customized according to customer feedstock condition and production target.
This solution is suitable for oil recyclers, industrial refineries, environmental companies, used oil treatment centers, circular-economy projects and investors in regenerated base oil production.
