How to recycle plastic into oil with pyrolysis plant?

If you want to recycle plastic into oil with the pyrolysis plant, firstly you should make sure that the kind of your raw material can be recycled into oil. Generally, the plastics we recycle for pyrolysis plant include: pure PP/PE/PS/ABS plastics, mixed plastics, food packaging bag, paper-mill waste, plastic household waste, etc. The purer the plastics, the higher the oil yield. For example, the oil yield of general plastics is 30%-90%, but the pure PP/PE/PS plastics can even reach 95% due to its high purity. However, you must know that PVC and PET can not be recycled into oil, so when you recycle waste plastic, you had better refuse recycling PVC and PET plastic.

Oil yield of different kinds of waste plastics

When the raw material is not a problem for you, you can use pyrolysis plant to recycle plastic into oil. Then we will introduce the detailed process of recycling plastic into oil with pyrolysis plant:

1. Pyrolyzing: Put the plastics into the reactor of the pyrolysis plant, and heat the pyrolysis plant. When it is heated to a certain temperature, the plastics will be cracked to generate oil gas.

2. Cooling: The oil gases are cooled into oil through the multi-stage cooling system. Our pyrolysis plant adopts three-stage cooling system, including 2 vertical condensers, 2 horizontal condensers and 2 cooling towers to obtain sufficient cooling effect. After going through the cooling system of the plastic pyrolysis plant, almost all the oil gas will be recovered, and we can recycle plastic into oil.

3. Waste gases purification: In addition to the oil gas, the pyrolysis plant also produces some uncondensable gases when recycling plastic into oil. The uncondensable gases are usually recycled for heating the reactors of plastic pyrolysis plant or other heating purposes. The exhaust gas produced by the plastic pyrolysis plant to recycle plastic into oil is treated by the dedusting and deodorization system, which meets the environmental protection standards and will not cause pollution to the environment.

4. Discharging carbon black: After collecting all oil gases in the pyrolysis plant, we need to cool down the recycling plastic into oil machine. Then we can discharge the carbon black from the reactor to prepare for the next step of recycling plastic into oil process.

Obviously, the pyrolysis process is not very complicated, but if you want to buy plastic pyrolysis plant, you should make the decision carefully, because the plastic pyrolysis plant from different manufacturers has different advantages, you can contrast them seriously.

Henan Doing Company has three types of plastic pyrolysis plant: batch type plastic pyrolysis plant, semi-continuous plastic pyrolysis plant and continuous plastic pyrolysis plant.

Different types of pyrolysis plant for sale

• The processing capacities and advantages:

1. The batch type plastic pyrolysis plant is from 100kg, 500kg to 18T/D and 20T/D, which is suitable for trial running because it needs relatively little money and easier installation.

2. The semi-continuous plastic pyrolysis plant is from 1T/D to 20T/D which has high efficient because there is no need to cool down before removing the carbon black.

3. The continuous plastic pyrolysis plant is from 15 T/D to 50T/D, which can help you recycle more plastics. It can work continuously to recycle plastic into oil up to 100 days and cost fewer labor for its fully automatic PLC control system.

Besides, DOING Company also has professional technical team to provide you with full services such as purchasing guidance, equipment installation and maintenance.
