Pyrolysis Oil Plant Design

What Is Pyrolysis Plant?

Pyrolysis is a kind of chemical degradation process, which happens at high temperatures under an oxygen-free atmosphere. It is commonly used to process organic materials, which is called biomass pyrolysis. And the end products include charcoal, wood vinegar, and tar. Besides, pyrolysis can also be used to treat plastic waste, old tires, rubber products, oil sludge, etc. to produce pyrolysis oil, carbon black and steel wire (tire). So it is also known as pyrolysis oil plant. Because it can largely reduce the volume of the waste, pyrolysis is very popular in municipal solid waste management. Let’s review the main equipment and the general working process.

Main Equipment

The core part of the biomass pyrolysis plant is carbonization furnace, which is of rotary design. While the pyrolysis reactor is the main section of pyrolysis oil plant. Beston has rotary and horizontal reactors to choose from.

Of course, there are various parts used, such as the condenser, discharging system, etc. Some investors will also buy pre-treatment equipment and further processing equipment.

General Working Process

In fact, the pyrolysis process for biomass waste and municipal solid waste are similar. Generally, it includes pre-treatment, pyrolysis, discharging and de-dusting system.

1. Pre-treatment System

This section aims to improve the quality of raw materials. The ideal water content is less than 15%, and the size is smaller than 15 mm for biomass waste and smaller than 20 mm for tires or plastic waste. Then you need to pre-heat the reactor first to remove the air inside.

2. Pyrolysis Process

Pyrolysis is happening under high temperatures. The carbonization temperature is between 300 -600 degrees, while the pyrolysis temperature for MSW is 200-450 degrees. During this process, it will produce combustible gas, which can be purified and then used as fuel to heat the reactor. Meanwhile, the hot gas will go through the condenser to separate other end products. Generally, the quality of the reactor matters the output of the end products.

3. Discharging System

The difference is that the biomass pyrolysis plant can work continuously, which means you can discharge charcoal while feeding. However, for batch pyrolysis reactor, it takes time to cool down first, and then discharge carbon black after the pyrolysis is completed.

4. De-dusting System

This system is used to purify the tail gas to meet the emission standards.

Advantages of Pyrolysis Plant

1. Reducing Solid Waste

Pyrolysis plant is very popular among investors. One of its main advantages is the reduction in the volume of waste. As we know, more and more solid waste occupied the valuable lands, and some even take hundreds of years to degrade. However, pyrolysis can quickly reduce waste without pollution. Beston pyrolysis plant has been installed in many countries, such as the UK, Romania, Brazil, Korea, etc. 

2. Make Money from Waste

Through pyrolysis, we can get various end products, such as charcoal, pyrolysis oil, etc. Due to the wide applications of the end products, you can sell for money.

As pyrolysis technology is getting mature, it is wise to invest in a pyrolysis plant for waste recycling. Besides, please remember to find a reliable and experienced manufacturer, such as Beston Machinery, for your business.
