Used Lube Oil Recycling Plant
Used lube oil is contaminated lubricating oil that has lost its effectiveness. It contains up to 90% valuable base oil that can be recycled. Recycling it transforms waste into a resource, protecting the environment, conserving energy, and reducing hazardous waste. It’s a smart, sustainable way to turn old oil into new opportunities for a greener world.
Recycling process of Used Oil is carried out in 4 stages:
- Pretreatment: In this stage used oil goes through screening process and chemical treatment
- Dehydration: In this stage water and fuel is separated from Used Oil
- Distillation: In this stage base oil is distilled from Used Oil under ultra-high vacuum.
- Polishing: In this stage received base oil from distillation process is treated to enhance its color and properties to make it ultra fine, as good as virgin oil.

Available Technologies for Distillation
WFE (Wiped Film Evaporator)
- WFE works with short path distillation technology, as result the Used Oil spends minimum time on hot surface which decrease the risk of thermal cracking and degradation, preserving the quality of the base oil.
- Due to indirect heating system WFE provides longer lifespan.
- Fully Automated (SCADA + PLC) & Continuous Process.
Available Capacities: 25 TPD, 50 TPD, 100 TPD, 200 TPD.
Column Evaporator
- Column-type evaporators are more preferable when the production capacity is less than 30 TPD due to their low initial cost.
- Multiple cuts can be separated by one evaporator.
- Batchwise process & Semicontinuous process using PLC.
Available Capacities: 10 TPD, 14 TPD, 20 TPD, 30 TPD.
Available Technologies for Polishing
Regenerative Media
- Continuous process
- Same filtration media can be used up to 200 times
- No hazardous waste is generated, easy disposal.
- Up to 1.0 ASTM D1500 color can be achieved.
Activated Carbon
- Batchwise process
- Zero Disposal – After use it will be disposed in firebox and converted into fly ash.
- Up to 1.5 ASTM D1500 color can be achieved.
Clay Treatment
- Continuous process
- Disposal is Complicated though preferred in many countries due to low production cost.
- Up to 1.7 ASTM D1500 color can be achieved.
