Plastic Pyrolysis Technology Process

We all know that there are mainly two types of pyrolysis plant for sale in the market: batching and continuous tyre to oil pyrolysis plant. Clients always feel confused what is the right choice for them as they don’t know too much about the pyrolysis plant.

What is pyrolysis technology?

The pyrolysis method for recycling used tyre is a technique which heats whole or shredded tires in a reactor vessel containing an oxygen free atmosphere and a heat source. In the reactor the rubber is softened after which the rubber polymers continuously break down into smaller molecules. These smaller molecules eventually vaporize and exit from the reactor. These vapors can be burned directly to produce power or condensed into an oily type liquid, generally used as a fuel. Some molecules are too small to condense. They remain as a gas which can be burned as fuel. The minerals that were part of the tire, about 40% by weight, are removed as a solid. When performed well a tyre pyrolysis process is a very clean operation and has nearly no emissions or waste.

Continuous Pyrolysis Plant

By this type of machine, workers should fill the raw material, for example, the waste tyre, plastic with a batch of raw material and take the process, and then after cooling down and removal of the carbon, the next process will happen. Batch pyrolysis plant is is suitable for small capacity customers. It needs feeding time for one and a half hour, processing time for eight to nine hours. It is more traditional, so it is cheap enough for people who haven’t prepared enough fund for this project.

Advantages of Batch Pyrolysis Plant

● Easy to operate by workers.

● Low investment but high profits.

● Quality end product-carbon black and pure oil.

● Different kinds of raw materials can be pyrolysis, for example, waste tyre, plastic and waste rubber.

● With mature devices and advanced systems, our batching pyrolysis plants could promise you the production process.

● Quality final products ( carbon black, oil and steel wire) will create great benefits for you and can help you get your investment back very soon.

Pyrolysis oil distillation machine

Capacity: 500L to 50 tons per day

Raw materials: waste tyre oil, waste plastic oil, waste engine oil, waste rubber oil etc

Product: diesel or base oil or gasoline.

Technology: Normal pressure or negative pressure distillation

The waste oil to diesel fuel refinery equipment/machine is applied to recycle the waste liquid oil (such as crude oil, used engine oil, waste tyre or plastic oil from pyrolysis plant) into diesel, gasoline or base oil(from used engine oil). It mainly includes oil distillation kettle, rectifying tower, oil-gas cyclone sedimentation tank, condensation system, oil storage tanks, vacuum system, heating system, emission controlling system, feedstock pretreatment system.

Main parts introduction of the system

1) Heating system

It includes the fuel tank, heater, heating furnace. The advantages are high heating-efficiency, little heat loss, high heating-speed. The oil heater can be controlled the input heat that make sure the whole system stability during running.

2) Distillation system

The system is including distillation kettle, rectifying tower, cyclone sedimentation tank, condenser, oil storage tanks. In the system, the distillation kettle can not heat, but the heating furnace. The feedstock is heated circulated in the heating furnace and reaches the distillation cuts temp. Because of the special inside structure designing of the rectifying tower, it can increase the oil quality; the cyclone sedimentation tank reduces the most ash of the oil; the condenser is tube type and easy to open for cleaning daily.

3) Vacuum system

The vacuum buffering tank and vacuum pump are included in the system. It is negative pressure distillation, which can reduce the distillation cuts temp, not only saving the energy but also more important is greatly increasing the single unit output and oil quality.

4) Waste gas recycling system

There are water seal and back fire device in the system. It not only recycles to use the non-condensable gas for heating, but also solves the environment pollution and save fuel in some ways.

5) Emission controlling system

It is including water tank, emission controller, and the induced draft fan. The emission can meet the international environment requirement after this system.

6) Intelligent electricity controlling system

The system is including the display cabinet and collector of parameters on site. The temp, pressure, liquid level can be showed on the cabinet, it is also high temp, high pressure and low or high level showing functions, which reduces the risk and waste because of the human factor.


l Safety

Safety is the most important factor in the whole process. We had successfully researched some safety devices which ensure the machine can work safely.

Safety valves, alarming device and the pressure gauge etc.

We also have oil-water separator which can stop the oil gas recycle to the reactor, which could avoid the accident.

High degree of automation:feed the waste oil, crude oil automatically ,to pump oil automatically.

l Energy saving:

Well sealing for heating system, no gas leak and saving fuel.

Continuous feeding with automatic feeder, no gas leak.

Recycling of exhaust gas and scientific fire channel design can save energy and thereby reducing costs.

l Environmental friendly

The whole process is all sealed, won’t release any gas harmful to human and environment.

Well water dedusting system can avoid black smoke.
