DOING Pyrolysis Plant---Plastic to Fuel Pyrolysis Process

Plastic to oil pyrolysis process is an environmental and efficient method of converting waste plastic into usable fuel oil through the process of pyrolysis. Pyrolysis is a thermochemical decomposition of organic material at elevated temperatures in the absence of oxygen. This process breaks down the long-chain hydrocarbon molecules in plastic into shorter chain molecules, resulting in the production of fuel oil, carbon black, and combustible gas.

Waste plastic to fuel pyrolysis plant

Here is a simplified explanation of the plastic to oil pyrolysis process of DOING plastic pyrolysis plant:

1. Feedstock Preparation: Polypropylene (PP), polyethylene (PE), acrylonitrile-butadiene-styrene copolymer (ABS), polystyrene (PS) and other typical waste plastics like household plastic, medical plastic, aluminum plastic composite materials, etc. can be pyrolyzed.

2. Pyrolysis: The waste plastic is then fed into a waste plastic pyrolysis plant reactor, which is a chamber where the thermal decomposition takes place. The reactor is typically heated to temperatures ranging from 300 to 800 degrees Celsius.

3. Heating and Vaporization: As the temperature rises, the plastic waste undergoes thermal degradation, breaking down into smaller molecules. This process involves the heating and vaporization of the plastic, transforming it into a gaseous mixture(oil gas).

4. Condensation: The oil gas is cooled by multiple stage condensers, leading to the condensation of the vapors.

5. Product Recovery: The condensed vapors are then collected and separated into three main fractions: liquid plastic pyrolysis oil, gas, and solid residue.

• The liquid oil extracted from DOING waste plastic pyrolysis plant, known as pyrolysis oil or plastic-derived fuel, can be used as a substitute for conventional fuels in applications such as heating various boilers or furnaces, power generation, or being further refined into non-standard diesel fuel by waste oil distillation plant.

Plastic pyrolysis oil applications and usages

• The gas can be recycled and used as a source of energy for the pyrolysis process itself after being purified.

• The solid residue, also called char or carbon black, can be further processed to produce activated carbon, used as a deodorant and adsorbent, and can also be used as a filler in the production of tires or rubber products.

It's important to note that the quality and composition of the final products can also vary based on the types of plastics being processed. Additionally, proper environmental and safety measures should be implemented to ensure the efficient and sustainable operation of plastic to oil pyrolysis facilities.
