What are the products of pyrolysis oil distillation?

DOING not only provides complete pyrolysis equipment to obtain the pyrolysis oil, but also the equipment to further distill the pyrolysis oil. The main products of pyrolysis oil distillation include diesel oil, asphalt and non-condensable exhaust gas.

Pyrolysis oil distillation equipment

Diesel Oil (85%): The primary product of pyrolysis oil distillation is diesel oil. This diesel can be used in a wide range of applications, such as boilers, generators, burners, agricultural machinery, construction machinery, and ship engines.

Asphalt (10%): Another significant product is asphalt. It can be used for road paving or sold to asphalt plants.

Non - Condensable Exhaust Gas (5%): A small portion of the output is non - condensable exhaust gas. This gas can be recycled to heat the reactor, saving fuel and enhancing the efficiency of the entire process.

Applications of the outputs of pyrolysis oil distillation

The specific process of pyrolysis oil distillation includes the following steps:

Feeding

First turn on the oil pump to pump the pyrolysis oil into the distillation reactor until the reactor is full of pyrolysis oil, then close the reactor door. DOING pyrolysis oil distillation equipment reactor is vertical, and there is a heat transfer oil coil in the vertical reactor. This design can first save fuel, and secondly, it can achieve rapid heating and save distillation time. At the same time, the vertical reactor can also achieve the purpose of automatic slag discharge, which is fast and safe.

Distillation

Turn on the burners and start heating the reactor of pyrolysis oil distillation equipment. Indirect heating can extend the service life of the reactor. As the temperature continues to rise, the oil-gas will be continuously distilled out.

Cooling

Oil-gas will enter the cooling system through the pipeline. The circulating water in the cooling system will cool the oil-gas into liquid oil and enter the oil tank. The oil-gas will not contact the circulating water, and the circulating water can be recycled.

Decolorization and deodorization

The liquid oil in the oil tank is pumped into the decolorization and deodorization tanks through the oil pump to remove the wax and gum in the liquid oil, and at the same time remove the unpleasant smell of the liquid oil. We can also provide a solution for decolorization using solid catalysts, which is more environmentally friendly.

Three types of pyrolysis oil to diesel equipment

Further purification

Generally, after the previous process, you have already obtained good quality diesel. If you want to get better quality, light yellow color diesel, then you can add a purification system to further purify the diesel.

Final products

In the end, you can get 85% diesel and 10% asphalt, and 5% of the exhaust gas.

In summary, pyrolysis oil distillation is a highly efficient process that yields valuable products such as diesel oil and asphalt. With DOING advanced pyrolysis oil distillation equipment, you can ensure a smooth and efficient operation.
