Deep Treatment Deep Refine
Optional continuous solvent extraction and adsorption finishing loops extract aromatics and lower acid numbers to reach higher-tier Group I/II base oil standards.
Core Process Technology Modules
From intake chemistry stabilization to finished refined output, the industrial footprint follows strict modular controls.
Pretreatment
Removes water matrices, particulate sludge, and light fractions smoothly.
Thin Film Distillation
Enables ultra-fast macromolecular separation under high vacuum ranges.
Fractionation
Splits target streams accurately into distinct SN150, SN350, or SN500 Viscosity Cuts.
Refining
Maintains high-density solvent extraction or active clay adsorption loop polishing.
Finishing Output
Yields highly stable, marketable commercial base oil batches ready for blending.
Detailed Process Introduction
An in-depth breakdown of our mechanical processing stages, addressing rigorous feasibility metrics for industrial buyers and engineering leads.
01 / Pretreatment System
Stabilizing Critical Raw Feedstock Qualities
The initial chemical-physical stage isolates volatile moisture, grit, and suspended metallic debris. This prevents rapid scaling and fouling down the thermal processing line.
- Efficient Particle Dehydration: Lowers cross-contamination risks.
- Hardware Lifespan Protection: Extends column and exchanger runtimes.
02 / Thin Film Distillation
High-Speed Separation Under Controlled Vacuum
By forcing raw stock into a controlled uniform liquid film, target fractions vaporize almost instantly. This brief contact window avoids thermal cracking and preserves clear lube parameters.
- Minimal Thermal Stress: Reduces coke formation inside the lines.
- Continuous Throughput Logic: Maximizes daily volumetric recovery.
03 / Fractional Distillation
Isolating Standard Commercial Oil Cuts Separately
Our fractional column structures divide vapors via accurate boiling cuts. This allows operators to draw clear, high-purity product lines matching precise viscosity benchmarks.
- Versatile Output Management: Yields multiple distinct base oil cuts concurrently.
- High Cut Consistency: Simplifies regional lubricant formulation blending tasks.
04 / Solvent Extraction Refining
Deep Odor, Sulfur, and Aromatics Extraction
This solvent wash loop targets polar molecules, ring structures, and trace acid matrices. It transforms raw distillates into brilliant Group-II quality equivalents with solid thermal stability.
- Visible ASTM Color Optimization: Strips dark polymeric matrices.
- Enhanced Sulfur Performance: Helps operators target stricter compliance limits.
05 / Adsorption Finishing
Final Visual Polish for Commercial Market Demands
Utilizing active media matrices, this polishing step removes tiny reactive traces, locks in clear storage longevity, and boosts market value.
- Long-Term Stability Assurance: Minimizes oxidation-driven color reversion.
- Polished Viscous Brightness: Boosts sales prices across commercial channels.

Frequently Asked Questions
Essential answers regarding industrial equipment supply boundaries and raw feedstock compatibility.
The systems process a wide range of used lubricating oils, automotive engine oils, vacuum hydraulic fluids, clear transmission oils, and mineral-based industrial oils.
No. VBOLT focuses strictly on core equipment supply, process loop engineering, PLC software integration, and assembly supervision. Local civil site preparation and civil building structures are entirely managed by the buyer's local contractors.
Yes. While standard vacuum distillation manages baseline fraction separation, reaching tight low-sulfur limits (such as sub-50 ppm scales) requires coupling our specialized continuous solvent extraction or catalytic polishing units to strip recalcitrant thiophenic structures.
