What process is involved in producing fuel oil from waste tires?

The DOING process for pyrolysis of waste tires into fuel oil was developed around a process of cryogenic cracking, condensation and liquefaction, with steps including pre-processing, feeding, heating, cooling and separation, tail gas and flue gas treatment. The details processes of producing fuel oil from waste tires are as follows:

waste tires to fuel oil pyrolysis plant process

1. Pretreatment stage

Waste tires are processed according to different designs of pyrolysis plants DOING. For batch pyrolysis plants, the tire can be pulled out of the steel wire first and then put into the reactor as a whole or put into the reactor directly without pulling out the steel wire. For semi-continuous type and fully continuous type pyrolysis plants, it is necessary to first pull out the steel wire and tear the waste tire into small pieces to facilitate subsequent feeding.

2. Pyrolysis reaction

The pre-treated waste tires are placed in the pyrolysis reactor and heated to 280°C to 350°C in an oxygen-free environment to decompose rubber tires and organic matter and obtain fuel oil, carbon black and gas.

3. The recovery of oil and gas

The decomposed oil and gas is cooled by a cooling system, and the gaseous oil is converted into a liquid, usually by circulating cooling with water. There are tube-in-tube condensation systems and water tank condensation systems for you to choose from.

4. Solid separation

The remaining solid material, carbon black, is separated from the metal and can be sold to industrial users and recycled. For example, the metal into wire, the carbon black into briquetting, oil into diesel.

5. Exhaust gas control

Non-condensable combustible gases are used as a self-sustaining heat source for pyrolysis furnaces, and the remaining exhaust gases need to be purified, desulphurized and dust removed to ensure harmless emissions and meet environmental protection requirements.

The above is a relevant introduction to the DOING tire pyrolysis plant process involved in producing fuel oil from waste tires. Here is a waste tire to fuel oil pyrolysis plant working process 3D animation running video for your reference:

The waste tire to fuel oil pyrolysis production process designed by Henan DOING company has following significant advantages: first, the tempture control of the waste tire pyrolysis process is precise, efficient and energy-saving, which can effectively improve energy utilization efficiency and ensure high output; second, this process can create good resource recycling benefits. The tire pyrolysis oil can be widely used for heating uses or further refined into diesel fuel after purification treatment, which has high economic value. The carbon black can be used for reprocessing, and the steel wire can be recycled for sale. In addition, the entire waste tire pyrolysis process is equipped with environmental protection devices, such as exhaust gas purification, desulfurization devices, dust removal equipment, etc., which has signification environmental advantages.
