Mixed Waste Oil Distillation for Industrial Fuel Fractions
VBOLT Mixed Waste Oil Distillation Plant is configured for tested hydrocarbon-based waste-oil streams. It combines dehydration, vacuum distillation, condensation, and project-specific purification to recover fuel-range fractions.
Feedstock compatibility, achievable recovery, product properties, operating mode, and permitted end use depend on laboratory analysis, process configuration, product testing, and local regulations.
Project options and performance objectives, subject to feedstock analysis and testing, may include:
- Higher diesel recovery rate
- More stable fuel quality
- Lower energy consumption
- Cleaner and safer production process
- Flexible raw material adaptability
- Long-term industrial continuous operation
The system is intended for qualified waste-oil recyclers, industrial fuel projects, environmental service companies, and operators with defined feedstock, product, permitting, and residue-handling requirements.
Applicable Raw Materials
After representative sampling and laboratory evaluation, the plant may process selected hydrocarbon-based waste-oil streams, including:
- Waste lubricating oil
- Waste engine oil
- Hydraulic oil
- Gear oil
- Used transmission oil
- Marine waste oil
- Industrial machinery oil
- Heavy fuel oil residues
- Contaminated mixed oil
- Light pyrolysis oil mixtures
- Tank bottom oil sludge
- Black waste oil with impurities
The plant is designed for feedstocks within an agreed specification. Excess water, halogens, coolants, reactive chemicals, and unknown waste require separate handling and evaluation.
Final Products
Depending on feedstock analysis, cut points, purification route, and test results, potential product and by-product streams include:
Main Product
- Non-standard diesel fuel
Optional Upgraded Products
- Light fuel oil
- Industrial burner fuel
- Heating fuel oil
- Low sulfur fuel oil (optional upgrading system)
By-Products
- Asphalt residue
- Light gas fraction
After laboratory testing and confirmation of applicable specifications, fuel-range products may be considered for permitted stationary or industrial uses such as:
- Industrial boilers
- Diesel burners
- Construction machinery
- Generators
- Industrial heating systems
- Marine fuel applications
Process Flow
The configured process uses staged dehydration, vacuum fractionation, condensation, purification, product testing, and residue handling.
1. Raw Material Feeding
Waste oil is pumped into the feed tank and preheated for initial dehydration.
2. Heating & Vacuum Distillation
The oil enters the distillation reactor under vacuum conditions. Different oil fractions are separated according to boiling points.
3. Oil Gas Condensation
The evaporated oil gas passes through the condensation system and becomes liquid fuel oil.
4. Purification Process
The distilled fuel is further purified through filtration and optional catalytic treatment to improve color, odor, and fuel stability.
5. Final Fuel Storage
Tested fuel-range product is transferred to designated storage tanks. Any use or sale remains subject to product specifications and local regulations.
6. Residue Discharge
Heavy residue is discharged to the configured collection system for testing, storage, and compliant treatment or disposal.
Core Technical Advantages
Advanced Vacuum Distillation Technology
Lower distillation temperature helps limit thermal cracking and supports controlled fraction recovery.
Project-Specific Recovery Targets
The heat-transfer and fractionation design is selected from the feedstock analysis and target cut points; recoverable output is project-specific.
Configured Operating Mode
The system can be configured for batch or continuous operation according to feedstock, capacity, maintenance, and project requirements.
Intelligent Temperature Control
PLC control supports monitored temperatures, pressure, alarms, and operating sequences; site safeguards and operating procedures remain project-specific.
Energy Saving Design
The heat-recovery package is configured to reduce avoidable fuel use within the selected capacity and operating conditions.
Defined Feedstock Compatibility
Processes selected waste-oil blends within the agreed feedstock specification and laboratory test basis.
Environmental Control Interfaces
Provides configurable vapor, non-condensable gas, residue, and wastewater control interfaces; the final site must meet applicable permits and local requirements.
Plant Capacity Range
Reference capacities are shown below. Final throughput depends on feedstock properties, operating hours, product targets, utilities, and the selected process configuration.
| Plant Type | Daily Capacity |
|---|---|
| Small Scale Plant | 1-5 Tons/Day |
| Medium Scale Plant | 6-20 Tons/Day |
| Large Industrial Plant | 20-100 Tons/Day |
| Customized Project | Available |
Custom batch or continuous configurations are available after project and feedstock review.
Preliminary Fuel-Fraction Assessment
No fixed sellable-fuel yield can be stated without representative sampling, laboratory distillation, mass-balance review, and defined product specifications.
| Raw Material Type | Assessment Basis |
|---|---|
| Waste Lubricating Oil | Laboratory distillation required |
| Waste Engine Oil | Laboratory distillation required |
| Mixed Industrial Waste Oil | Composition-dependent |
| Pyrolysis Oil Mixture | Compatibility testing required |
VBOLT engineers can prepare a project-specific preliminary mass balance after evaluating representative feedstock samples and target product specifications.
