Waste Oil to Base Oil Plant
In recent years, the vast proliferation of machinery and vehicles has led to an exponential increase in the generation of waste oils. Originating primarily from automobile engines, industrial processes, and other mechanical systems, these used oils, if improperly disposed of, pose significant environmental threats due to their toxic constituents and non-biodegradable nature.
While the traditional solution has been to burn or dispose of waste oils, these methods are both environmentally harmful and wasteful of a valuable resource. As the demand for lubricants grows in parallel with the surge in machinery and transportation, it becomes imperative to find sustainable avenues for used oil’s reintroduction into the economy.
Enter waste oil distillation equipment—a beacon of innovation in this context. This equipment is meticulously designed to recover and refine used lubricating oil, transforming it back into a high-quality base oil. Leveraging advanced atmospheric and vacuum distillation techniques combined with solvent extraction, these systems ensure the removal of contaminants, water, and lighter or heavier fractions. The resulting base oil not only matches the quality of virgin base oils but also provides a more environmentally sustainable and economically viable solution to the waste oil to base oil conversion challenge.
By deploying waste oil distillation equipment, we are presented with an invaluable opportunity: to harness the latent value in discarded oils and simultaneously contribute to a sustainable and eco-friendly future.
Application
PurePath has designed the re-refining technologies for used lubricating oil to produce near virgin quality base oil ranging from SN80 to SN500 by using different technologies such as full continuous distillation, wiped film evaporation, and short path distillation. In the meanwhile, we have also developed a base oil solvent extraction plant to help you get rid of the annoying clay refining system and allow you to refine the base oil to meet API group 1+ standards.
PPGT-TB Waste Oil to Base Oil plant is specially targeted for waste motor oil, hydraulic oil, crack case oil, gearbox oil, transmission oil, slop oil, etc. PPGT-TB waste oil refinery helps relieve the energy crisis as well as create profits with a low operation cost.
For additional solutions in waste oil processing and lube oil refining, consider exploring our Waste Oil to Diesel Plant and Lube Oil Refining Plant offerings. These innovative technologies can further enhance your sustainability and profitability goals.

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.
