What is the oil yield of pyrolysis plant?

The role of the pyrolysis plant is only to deal with all the oil contained in the raw material by pyrolyzing, so the final oil yield is determined by the oil content of the raw materials largely. Different raw materials have different oil content, the following is the oil output of the common raw materials for pyrolysis plant:

1. General rubber

Big car tires, truck tires, OTR tires45%-52%
Small car tires, motorcycle, bicycle tires35%-40%
Rubber cable sheath, rubber soles35%
All kinds of rubber sheets or carpets30% 
Unclassified rubbers35%

2. General plastics

Except for PVC and PET, almost all other plastics can be used for pyrolysis to oil.

Pure PP/PE/PS plastics90%-95%
Pure ABS plastics40%
Pure white plastic sheets70%
Food packaging bags40%
Paper-mill waste60%(dry)15%-20%(wet)
Plastic household garbage30%-50%
Alumnium plastic50%

3. Oil sludge

There are floor oil sludge, tank bottom oil sludge, refinery oil sludge, etc. The oil content of different sludge determines the oil yield.Therefore, before processing the oil sludge, it is recommended to check the oil content of the oil sludge. The following is the oil yield of common oil sludge:

Oil sludge15%-70%
Oil sands20%-30%
Coal car oil residue20%-30%

However, these are theoretical oil yield. The actual oil yield of pyrolysis plant also has a certain relationship with workers' operation and equipped configurations of pyrolysis plant.

1. Workers' operation

The best temperature at which the raw material is most fully pyrolyzing is between 280°C~320°C, while the workers who have been professionally trained and can operate the equipment skillfully and accurately have a more accurate grasp of pyrolyzing time, temperature, etc., so that the oil yield of pyrolysis plant can be improved.

2. Equipped configurations of pyrolysis plant

The configurations of pyrolysis plant developed by different manufacturers are also different, which also affect the oil yield of the pyrolysis plant. Take DOING pyrolysis plant as an example, DOING technical team improved the designs of pyrolysis plant based on customer demands and feedback:

(1) 3-step cooling system

The 3-step cooling system all adopts tube condensation, which is the most commonly used and most effective condenser in the industry, thus to get fully cooling effect and improve the oil yield of pyrolysis plant.

(2) Vacuum device

Vacuum device is DOING's patented equipment, which can fully extract the oil gas in the pyrolysis reactor to improve the oil yield of the pyrolysis plant and enhance safety to avoid accidents.

DOING has a professional technical team to research our pyrolysis plant. In addition, we will provide customers with full services, such as pyrolysis plant selection, installation guidance and operation training, etc. So if you want to invest in a pyrolysis plant with higher oil yield and good performance, welcome to contact us!
