Not Just a Machine — A Complete Waste Oil Recycling Project Solution

Waste oil recycling is a project-based business. The correct process route must consider raw oil condition, target final product, local fuel standard, heating method, installation country, environmental requirement and long-term operating cost. VBOLT provides route-based technical solutions instead of simply supplying a single machine.

Raw Oil Complexity

Used oil may contain water, sludge, metal particles, additives, heavy residue and unstable components.

Product Target Difference

Base oil recovery and diesel recovery require different process routes, refining levels and equipment configurations.

Operating Stability

High-viscosity waste oil can cause coking, fouling and unstable distillation if the process is poorly designed.

Project Delivery

Customers need process design, layout design, equipment integration, installation guidance and commissioning support.

Core technology

Thin Film Distillation for High-Viscosity Waste Oil Separation

Thin film distillation is one of the key technologies used in the base oil recovery route. Compared with traditional kettle-type distillation, thin film distillation allows waste oil to form a thin and uniform film on the heated surface, improving heat transfer efficiency and reducing residence time.

This is especially valuable when processing high-viscosity used engine oil and waste lubricating oil, because poor heat transfer and long residence time can increase coking, fouling and unstable distillation operation.

  • Improves heat transfer efficiency through thin liquid film formation
  • Reduces residence time and helps minimize thermal degradation
  • Better suited for high-viscosity waste lubricating oil separation
  • Helps reduce coking and fouling risk during long-term operation
  • Supports stable recovery of base oil fractions under vacuum conditions

Technical focus

Thin film distillation is mainly used for base oil recovery and selected high-viscosity waste oil separation applications.

Product quality improvement

Refining Depth Depends on Final Product Target

Waste oil recycling quality is not determined by distillation alone. The final product quality depends on raw oil condition, process route, refining depth, operating parameters and local product requirements.

Professional Product Statement

Final product quality should be confirmed based on feedstock test data, actual process configuration, refining depth and local application standards. VBOLT recommends technical evaluation before final quotation.

Desulfurization

Can be configured for diesel-range fuel or fuel oil projects according to sulfur content and market requirement.

Decolorization

Improves product appearance and market acceptance for base oil or fuel oil applications.

Deodorization

Reduces unpleasant odor caused by unstable components, sulfur compounds or oxidation products.

Fuel Polishing

Improves cleanliness, stability and usability of diesel-range fuel or industrial fuel oil.

Solvent Refining

Used for base oil route to improve color, stability and remove selected undesirable components.

Quality Control

Typical evaluation items include viscosity, density, flash point, water content, sulfur and distillation range.
