Plastic pyrolysis plant can convert waste plastics into fuel oil and carbon black through a high-temperature pyrolysis process. Waste plastics are a common environmental pollutant. Except for PVC and PET, most waste plastics (PP, PE, PS, ABS or mixed plastics) can be converted into fuel oil, tar and paraffin through pyrolysis equipment. PVC and PET plastics are not suitable for pyrolysis, because they contain chlorine elements and benzene ring structures.
Pyrolysis Plastic Recycling
The excessive use of plastic products is often accompanied by the generation of a large amount of plastic solid waste (PSW), which poses a serious threat to the ecological environment. Every year, more than 60% of PSW enters landfills or is directly discharged into the environment. Therefore, plastic pollution control is imminent. Considering that plastics come from fossil fuels with high calorific value, pyrolysis technology of waste plastics has become a wise move to optimize the energy structure.
Plastic Waste Pyrolysis Project
As global plastic production increases, the problem of waste plastic disposal is becoming increasingly serious. Pyrolysis plastic recycling projects have attracted widespread attention as a method to convert waste plastics into high-value-added products. Waste plastic pyrolysis plants are an effective solution to cracking "white pollution". In addition, PVC and PET materials should be avoided during the pyrolysis process.

Plastic Recycling Pyrolysis Plant Application
Plastic Waste Pyrolysis Process
The pyrolysis process of waste plastics is simple and convenient. Pyrolysis plants can not only solve the problem of plastic waste disposal, but also produce renewable resources.
- Pretreatment: Waste plastics are first pretreated, including sorting, crushing, washing and drying. This removes impurities (including PVC and PET plastics) and moisture.
- High-temperature pyrolysis: The pretreated waste plastics are fed into a pyrolysis reactor. Under high temperature (450-650°C) and oxygen-deficient conditions, the pyrolysis system decomposes the waste plastics into small molecular gases, liquids and solid residues.
- Condensation: The gases and liquids produced by pyrolysis are condensed through a condenser to form liquid fuel oil.
- Separation: The condensed fuel oil contains components with different boiling points. At this time, they need to be separated through distillation equipment to obtain light gasoline, diesel and heavy fuel oil.
- Tail gas treatment: The tail gas produced by pyrolysis contains harmful substances such as dioxins, benzene and carbon monoxide. These harmful substances need to be removed through tail gas treatment systems, such as activated carbon adsorption, catalytic combustion or wet scrubbing.
- Solid residue treatment: The solid residue produced by thermal cracking is mainly carbon black, which can be used as fuel or other industrial raw materials.
Pyrolysis Oil To Diesel Process
The process of making diesel from plastic pyrolysis oil through waste oil distillation equipment usually includes the following steps.
Plastic Pyrolysis Oil Pretreatment
Separation of impurities: Use gravity sedimentation method to remove impurities such as solid particles and water to obtain relatively pure pyrolysis oil.
Distillation Separation
Heating: The pretreated pyrolysis oil is sent to the distillation tower and heated by the heating system. The heating method can be thermal oil heating, steam heating or direct combustion heating. The pyrolysis oil gradually heats up to the boiling point in the distillation tower and begins to vaporize.
Fractionation: Different temperature zones are formed in the distillation tower according to the different boiling points of the components in the pyrolysis oil. Low-boiling components such as gasoline fractions will be separated first in the upper part of the distillation tower. The diesel fraction is separated in the appropriate temperature zone and rises to a specific position of the distillation tower in the form of steam.
Condensation: The diesel fraction steam separated from the distillation tower enters the condenser. The steam is cooled and liquefied by heat exchange with cooling water or other cooling media to form liquid diesel.
Refining
The liquefied diesel is collected in a special storage tank as a preliminary diesel product. The preliminary diesel may still contain some impurities or undesirable components and need to be further refined. If the acid content in the pyrolysis oil is high, neutralization treatment is required to reduce corrosion to subsequent equipment.
Filtering
The pyrolysis oil is passed through the filter to further remove fine solid particles and impurities. This ensures that the pyrolysis oil entering the distillation equipment has a high purity.
Why Can't Plastic Pyrolysis Equipment Process PVC and PET materials?
Because PVC and PET will corrode the plastic pyrolysis machine, pollute the environment, and reduce economic benefits.
PVC is a chlorine-containing plastic that releases a large amount of hydrogen chloride during pyrolysis. Hydrogen chloride is a toxic gas that can cause serious harm to pyrolysis plants, human health and the environment. In addition, PVC will produce harmful substances (such as dioxins and furans) during pyrolysis, which are carcinogenic and persistent.
PET is a thermoplastic polyester that releases a large amount of ethylene glycol during pyrolysis. Ethylene glycol is a toxic substance that is harmful to human health and the environment. In addition, PET will produce harmful substances (such as terephthalic acid and carbon monoxide) during pyrolysis. The release of these substances will pollute the atmospheric environment and affect human health.
