Efficient Solution for Converting Mixed Waste Oil into High-Quality Base Oil
Mixed Waste Oil Re-Refining Plant is configured for tested, lubricant-based waste-oil blends. It combines pretreatment, vacuum distillation, and a project-specific finishing route to recover base-oil fractions.
Feedstock compatibility, achievable product quality, oil recovery, and permitted end use depend on laboratory analysis, process configuration, and local regulations.
▲ Applicable Raw Materials
This plant may process selected lubricant-based waste-oil streams after feedstock analysis confirms compatibility, including:
√ Tested mixed industrial lubricating oils
√ Contaminated lubricating oils
√ Used hydraulic, gear, machine, and transmission oils
√ Controlled blends with known composition
√ Recoverable oil from sludge only after separate pretreatment and laboratory evaluation
The system is engineered for variable feedstocks within an agreed design basis. Incompatible chemicals, excessive water, halogens, coolants, and unknown wastes require separate handling and evaluation.
▲ Final Products
Depending on feedstock analysis and process configuration, potential product and by-product streams include:
√ Base-oil fractions requiring testing and, where specified, additional finishing
√ Light and fuel-range by-products where permitted
√ Water and low-boiling distillate
√ Non-distillable residue requiring compliant handling
Recovered base-oil fractions require laboratory testing and, where specified, additional finishing before lubricant blending or industrial use.
▲ Core Process Flow
The plant adopts a mature and efficient re-refining process:
• Pretreatment System
Removes water, impurities, sludge, and suspended solids from mixed waste oil to ensure stable downstream operation.
• Vacuum Distillation System
Separates valuable oil fractions under negative pressure and low-temperature conditions, improving oil quality while reducing thermal cracking.
• Purification System
Uses the selected finishing route to reduce targeted color bodies, sulfur compounds, and oxidation products. Achievable product properties must be verified by laboratory testing.
• Cooling & Collection System
Condenses refined oil vapors efficiently and collects different oil fractions separately.
• Exhaust Gas & Environmental Protection System
Treats process vapors and non-condensable gas according to the project configuration. Site permits and local emissions requirements remain project-specific.
▲ Plant Advantages
√ Wide Feedstock Adaptability
Supports selected, tested waste-oil blends within the agreed feedstock specification.
√ Defined Process Basis
The design basis links feedstock analysis, fraction targets, process conditions, and product testing; recovery and quality are project-specific.
√ Energy-Saving Design
The heat-integration package is configured to reduce avoidable fuel use and operating cost within the selected plant capacity.
√ Fully Automatic Control
PLC automatic control system simplifies operation and improves production stability.
√ Environmental Control Package
Includes configurable vapor, gas, residue, and wastewater control interfaces; the final site must comply with applicable local permits and regulations.
√ Customized Capacity Solutions
Available in different processing capacities according to customer production requirements.
