Feedstock recycling and pyrolysis of waste plastics plant

Feedstock recycling and pyrolysis of waste plastics plant adopts the pyrolysis technology to achieve the plastic waste to fuel oil conversion. The Feedstock recycling and pyrolysis of waste plastics plant is a chemical process of breaking down large molecules of plastic into smaller molecules of oil, gas and carbon black. The following is the details about how to get fuel oil from plastic waste.

What is pyrolysis:

Pyro = heat. Lysis = break down.
Pyrolysis is chemical reaction. This reaction involves molecular breakdown of larger molecules into smaller molecules in presence of heat. Pyrolysis is also known as thermal cracking, cracking, thermolysis, depolymerization, etc.


Plastic pyrolysis is: the process of converting waste plastic into industrial fuels like Pyrolysis Oil, Carbon Black and Hydrocarbon Gas.

Plastic pyrolysis involves subjecting plastic to high temperature of 400 to 450 degree Celsius, in absence of oxygen. In case of oxygen is present plastic will start burning. During pyrolysis plastic breaks down into smaller molecules of pyrolysis oil, pyrolysis gas and carbon black. Pyrolysis is great a way of recycling waste plastics. This recycling and pyrolysis of waste plastics plant can also used for waste tire recycling.

1. Put dried plastic waste into reactor and the quantity shall be controlled under 2/3 of reactor for rotating more smoothly. Then close the feeding door.

2. The feedstock recycling and pyrolysis of waste plastics plant includes two stages. From 100℃ to 250 ℃ is the preliminary stage. The light oil gas shall be released at 100 ℃ and fluid oil shall be released at 120℃ . From 280℃ to 350℃is the top output rate interval. Oil gas will be collected into manifold, heavy particles and oil will be gathered and liquefied in center of manifold and drop down into the heavy oil tank. The lighter gas will rise up to the multi-functional oil condensers, then be liquefied into oil and stored in the oil tank. The incondensable gas through de-sulfuration and de-dusting by hydroseal will be led to heat the furnace for reducing the energy cost.

3. Cool down the plastic pyrolysis reactor after the process. Carbon black will be discharged automatically when the temperature falls down to 50-70 degrees.
