Waste Oil to Base Oil Plant – Reclaim, Refine, Reuse
Turn used lubricating oils into high-quality API Group I base oils with our proven PPGT-TB re-refining technology.
✔ Recover up to 85% usable base oil from waste lubricants
✔ Produce SN80–SN500 base oil that rivals virgin quality
✔ Environmentally friendly solution that reduces waste and maximizes profit
✔ Reliable vacuum distillation with advanced wiped film & short-path systems
Why Choose PPGT-TB Waste Oil to Base Oil Plant?
Our advanced re-refining technology converts waste motor oil, hydraulic oil, gearbox oil, transmission oil, slop oil, and more into premium base oils.
Key Benefits:
- Wide Product Range: Produce SN80 to SN500 base oils meeting API Group I+ standards.
- Cut Costs & Boost Profits: Save on raw oil purchases and generate new revenue streams.
- No More Acid Refining Hassle: Our solvent extraction process eliminates the messy Acid treatment method.
- Sustainable & Compliant: Reduce waste oil disposal, minimize environmental impact, and meet global regulations.
- Proven Technology: Combining continuous distillation, WFE wiped film evaporation, and short-path distillation for maximum yield and quality.
How It Works – Precision Engineering for Maximum Yield
The PPGT-TB Plant integrates a complete line of processing systems to ensure consistent base oil quality:
- Dehydration & Sedimentation – Removes water and solids from feedstock
- Fractionating & Reflux + LGO Stripping – Efficient separation of light fractions
- Thin Film & Short-Path Distillation – Advanced vacuum distillation for high-quality base oil
- Base Oil Polishing – Final refining to meet API Group I specifications
- Automated PLC/SCADA Controls – Reliable, safe, and easy-to-operate system
EXTENDED INFORMATION
There are three major heating methods which are commonly used in waste oil refineries. Electrical heating, Boiler and Furnace. Electrical heater is more often to be used in small scale of waste oil refinieries. The advantage of electrical heater is that it does have a wide range of heating temperature and it is an economic solution for using in small scale refineries.
On another hand, Hot oil boiler can be used in either of medium to large scale of waste oil refineries. Heating by boilel in heat exchangers are a very common way of heating in petrochemical industry. It is safe, efficient and controllable. However, most of hot oil boilers have a limit of heating tempeature which is below 380-350℃.
The furnace are usually used in large scale of waste oil refineries. It also has a wide range of heating temperature and there’s no requirement for thermal oil consumption comparing with hot oil boiler. However the furnace is usally in 18-20 meters tall.
Those waste are generally in 4 categories: gas, oily water, oil sludge and used adsorbents.The gas can be purified before emission or to be burned in a furnace;The oil sludge can be used for burning or as raw material for making bitumen; the oily water has to be purified by particular facilities or handed to the professional recycler; the used adsorbent can be used for burning or handed to the professional recycler.
The typical yield of waste oil refinery will be as following: 75% of base oil; 5% of water & light ends; 7% of light gas oil; 13% of oil sludge;
The quality of base oil is able to meet API group 1 and 1+ standards which could be as good as the virgin base oil after PurePath unique refining process. Those base oil can be either sold directly or to be further blended with additives for making new engine oil.
Please be freely to contact our sales representative for test reports of the base oil which was produced by our waste oil refineries.
PurePath is located in Chongqing city (Southwest of China).The nearest airport is Chongqing Jiangbei International Airport.
