Mingjie pyrolysis oil distillation plant can refine tire pyrolysis oil or waste engine oil into diesel or gasoline, making them reach a higher use value. The pyrolysis oil distillation unit is relatively simple to operate, and no secondary pollution will be generated during the distillation refining process.
Main Working Process of Pyrolysis Oil to Diesel

- Pump the pyrolysis oil into the reactor of the distillation plant.
- Heat the distillation reactor, and the tyre pyrolysis oil is distilled into oil and gas at high temperature. What remains is the heavy oil residue.
- The oil and gas are condensed and collected in the storage tank.
- The collected oil is purified and decolorized to finally obtain clean and transparent diesel.

Pyrolysis Oil to Diesel Project
The conversion of plastic pyrolysis oil into fuel oil (such as diesel, gasoline or heavy oil) requires processing through distillation equipment, thereby improving the quality and applicability of the oil. Waste oil distillation equipment plays a vital role in the pyrolysis oil recovery and refining process. The process of converting tire pyrolysis oil into diesel in distillation plant is mainly divided into two parts: distillation and refining.
In 2022, Mingjie Group completed the transportation and installation of MJZ-2 waste oil distillation machine for sale to South Korea.…

- Pump the pyrolysis oil into the distillation reactor, the hot oil pump will make the oil recycle in the reactor to avoid coking problems.
- Heat the reactor and pyrolysis oil will become the oil gas. Oil gas will go through distillation tower to light fraction condenser and be liquefied to be oil and stored in the light oil tank.
- In the condensing process, there is a part of gas that can not be condensed, the gas will go through the oil tank and vacuum system to the hydroseal.
- In the hydroseal, the syngas will be cleaned and desulfurized, after which, one part will be recycled as fuel for the reactor heating, another part of extra syngas will be burned out directly in the extra syngas burning room in case the temperature and pressure is too high in the reactor .
- In the pyrolysis oil distillation process , vacuum system will create a negative pressure environment for the equipment, to make sure safety production.
- During the pyrolysis oil distillation process, high temperature smoke will be generated. Emission will come out from furnace and go through the flue condenser for cooling down the temperature. then go through the dedusting scrubber for cleaning by water washing, ceramic rings adsorption and water spray, then the emission can be discharged into the air through chimney without pollution.
- After pyrolysis oil distillation process finished, cool down the reactor for 3-4 hours to reach about 200℃,the remaining heavy oil will be pumped out to oil gas condenser and stored in the heavy oil tank.
- Pump light oil from the storage tank to the pickling tank, add 98% sulfuric acid with a dosage of 2-5%, mix and sediment, which can remove the sulfide and colloid in the oil.
- After pickling washing, pump the oil into the alkaline washing tank for neutralization and remove the oxygenated chemicals, sulfide. Add 40% of the concentration of sodium hydroxide solution with a dosage of about 3%.
- In the pickling and alkaline washing process, the air compressor will provide compressed air to the tanks for mixing function.
- After alkaline washing, pump the oil into the activated clay tank for adsorption of the solid impurities. Slowly add 2-5% activated clay and mix for 2 hours. Meantime, use the steam boiler for heating, so that the oil temperature will be maintained at 70 to 90 degrees.
- After activated clay adsorption process, pump the oil to go through the plate-and-frame filter press to get the final clean and transparent non-standard diesel.
