Engine oil recycling purification machine, The engine oil can be used in many fields. As we all know, the waste engine oil may mix with gas, water and particles after long usage. The engine oil recycling machine can deal with waste lubricating oil. The high-quality base oil and a small amount of gasoline and diesel oil were obtained by vacuum distillation. After the pretreatment of waste oil pump into the distillation kettle, heating to the operating temperature, the required base oil and a small amount of gasoline and diesel. When the reaction is complete, the heating is stopped and the residual oil at the bottom of the kettle is removed. The machine has low production costs and produces high-quality base oil, an advanced waste oil recovery and treatment technology. It is suitable for large-scale, industrial production. And it is very environmentally friendly equipment.
engine oil recycling machine (vacuum distillation process) which is able to recover good quality light and heavy base oils with a high regenerate rate of more than 85% and low cost, it has practically negligible pollutants for the environment.
Used black engine recycling to base oil by vacuum distillation technology is the most effective process for lube oil recycling, the vacuum system is to refine waste oil in a batch process. Waste lube oil after pre-treatment will be pumped into a catalyst reactor we will add two kinds of catalyst blend with oil and heat in a distillation kettle under vacuum. as the boiling point of different products are different, with the temperature in the kettle rises, various cuts are liberated and rise as vapors, to be condensed in a condenser. The condenser, along with the heating kettle, is maintained under vacuum by a vacuum pumping system. The condensed products are available as different products corresponding to various kettle temperatures.
Process Operation Description:
- First, pump the waste lube oil after pre-treatment into a chemical reactor, add the chemical solution. Keep mixing the oil inside the distillation kettle. In the reaction make kettle the oil static after mixing, we have the impurities and part of the colloid at the bottom of reaction kettle separated. After this chemical catalyst treatment of oil, the oil will not be cracked even it is heated up to 400 degrees in the atmosphere. (in the atmosphere, without the treatment of the oil start to be cracked at 300 degrees, it is obviously declining the quality of recycled oil and recovery rate).
- After chemical treatment, the waste oil is heated by a distillation reactor, to control the oil temperature within 350 degrees through the heating furnace. As the temperature of the oil rises to around 55℃, the first cut off gasoline starts to release from the waste oil. As the temperature of the oil rises to around 110°C – 220°°C, the second cut of diesel are released from the batch. As the light oil cut tends to finish, there is a temperature rise indicating the completion of light oil. Lube Oil is the main product and its distillation starts at around 220°C and continues up to 350°C. The light base oil is distilled out around 220°C-300°C, and Most of the heavy lube oil distills out during 300°C -350°C. At the end of the process, the kettle bottom temperature begins to rise to mark its completion. Finally, the process ends when the residual material in the kettle does not vaporize, even at a temperature of around 350°C. At this point, the heating in the distillation process is stopped and the process is essentially complete. Can pump oil residual out to use as bitumen and heavy fuel oil. Output oil is light base oil and heavy base oil, like SN150 or SN300.

The working process of the oil purification machine
- Preheating
The engine oil purification machine uses two heating systems, one is to heat the distillation reactor with heat transfer oil. The engine oil purification machine needs to preheat the heat transfer oil for a certain period of time before starting up.
- Distilling
Heat the reactor with heat transfer oil and a burner at the same time. In a high temperature and oxygen-free environment, the distillation reactor will produce oil and gas after reaching a certain temperature.
- Cooling
The heavier oil and gas are purified by the catalytic tower, the purified oil and gas are cooled into liquefied oil through the condenser and stored in the fraction tank.
- Purifying
The non-condensable oil and gas in the condensing system is purified by a water seal and used as fuel to heat the distillation reactor.
- Decolorization and deodorization Feed the oil in the oil tank into the decolorizing pot, the white clay is added to stir to decolorize, and then the oil fully mixed with the white clay is pumped into the leaf filter to obtain a clear color oil, which is then finely filtered to remove impurities. You can get clean, bright non-standard diesel.
- Flue gas treatment
The flue gas produced by the heat-conducting oil furnace and the reactor is processed by the desulfurization tower and discharged into the atmosphere after meeting the national emission standards.
Used engine oil refining into diesel oil equipment
waste oil distillation machine can refine waste oil,such as tire pyrolysis oil, plastic pyrolysis oil, waste engine oil, black and heavy oil, curde oil, etc. into light diesel, the final diesel product could be used as alternative fuel in diesel burnes,enerators,heavy machinery and agricultural machiery,etc. The whole process includes high temperature distillation, circulation water cooling,catalyst deodorization and clay decolorization. Next, let’s see the detailed workflow of waste oil distillation machine.
Waste oil distillation machine
The main working flow of waste oil distillation machine is as follows:
- Pour the heat transfer oil into the heat transfer system, the heat conduction oil is mainly to preheat the system.
- When the temperature of the distillation reactor reach 290 degrees, turn on the burner to heat distillation reactor, and control the temperature of the distillation reactor between 380 degrees and 400 degrees, and the oil gas will generate;
- The oil gas will be cooled downed into light fuel oil through the cooling system and flow into the oil tank.
- Then, the light fuel oil can be purified through catalyst deodorization and clay decolorization to obtain diesel.
Compared with equipment from other manufacturers, our waste oil distillation machine has the following advantages:

The main working process of waste engine oil distillation machine
- Feeding
Feeding liquid waste engine oil into distillation reactor by oil pump. Then run the heat conducting oil into the tubing and heat it.
- Heating
First, heating the waste engine oil by the conducting oil in the tubing which hovered in the distillation reactor. When reach a certain tempature, heat the distillation reactor from the bottom by fuel. This double heating method can save the preheating time of waste engine oil and shorten the operation time of the project.
- Catalytic cracking
As it is heated, the waste engine oil in the distiller produces oil gas, which is then pumped into the catalytic tower. With the action of catalyst in the catalytic tower, the waste engine oil will be catalytic cracking into small molecular oil gas.
- Cooling
As the reaction progresses, small molecules of oil gas generated in the reactor will enter the cooling system and be cooled into liquid oil. The liquid oil can be collected into oil tank directly.
- Desulfurization
The flue gas produced in the process of fuel combustion is purified by desulfurization & purification tower to ensure no pollution to the air.
- Slagging
After all the reactions are complete, the distillation left is oil residue, its main component is asphalt. Because we use a vertical reactor, the asphalt can be easily clean up.
Waste oil refinery machine is a machine converts waste oil to diesel. It is an effective machine for recycling waste oil.
We adopt vacuum distillation system to refine waste motor&engine oil; this is the most effective method for refining the waste oil.
The waste oil will be pumped into reactor, and then the waste oil will be heated by the heat transfer oils. When the temperature of the waste oil rises, the waste oil will vaporize, and then we will add catalytic to purify oil or decoloration, after these processes the oil will be condensed into liquid. Thus the final product is liquid oil.
With the development of the economics and auto industry more and more engine oil, motor oil depreciation. The waste oil pollutes the water, also is a waste of energy. They are great harmful to the environment, they must be processed correctly, or they will pollute the environment. The waste engine&motor oil refinery machine can convert the waste motor&engine oil to diesel which can be directly used in diesel power generation, tractor, ship, etc.
Waste engine oil to diesel machine
People dispose of engine oil from their cars; truck and motor without knowing that they can be recycled to produce high-quality clean oil that can be re-used again in their vehicles and ships. The waste engine oil to diesel machine uses the most advanced technology to produce clean oil that can be used again and it doesn’t cause secondary pollution to the environment.
Waste engine oil to diesel machine is also called oil refining machine. It can refining waste oil(waste engine oil,motor oil, tyre oil, plastic oil etc) to clean diesel. The oil recovery yield is about 85% ( according to oil quality).
