Pyrolysis Plant

MoreGreen Pyrolysis Plant

The MoreGreen pyrolysis plant decomposes waste into oil vapor by high-temperature pyrolysis technology. Then the oil vapor enters the cooling system through the oil-gas separator, wherein the oil flows to the oil tank, and the pyrolysis gas passes through water seal to the gas recovery system to become the main furnace fuel. The dust passes through the dust removal system and is discharged after meeting the national environmental protection standards. At the same time, the automatic feeding process and cracking furnace generated steel wire and carbon black.

Waste To Oil Industry Brief

Is the pyrolysis plant worth investing in? No doubt! Because the waste to oil industry has very good prospects.

Waste tires are known in the industry as "black pollution," and recycling and disposal of used tyres have been a worldwide problem. According to authoritative research, there are as many as 1 billion used tires in the world in 2018, totaling more than 30 million tons. The annual production of plastic waste is even more alarming, with global plastic waste production reaching 360 million tons in 2018. Coupled with waste rubber and waste sludge, these wastes have brought tremendous pressure on global environmental protection. Their recycling and treatment have been highly valued by all countries. So, is there any equipment that can effectively handle these wastes?

A pyrolysis plant is one of the best options. It plays a key role in the process of digesting the above-mentioned garbage, and can also convert waste into energy, thereby obtaining considerable economic benefits, and killing two birds with one stone. After the waste has undergone a complete set of automated processes such as crushing and pyrolysis, most of the waste can be reused to obtain high value-added renewable resource products on the premise of safety and environmental protection.

Taking waste tyres as an example, 1 ton of used tyres (rubber) can produce 0.35 tons of carbon black, 0.45 tons of waste tire (rubber) oil, 0.12 tons of steel wire and some combustible gases by high-temperature pyrolysis. Compared with waste direct landfill, combustion incineration and other treatment methods, high-temperature pyrolysis technology are safer and more environmentally friendly, saving energy and conforming to the development trend of the times.

Since 2009, MoreGreen has started to cooperate with well-known scientific research institutions and universities and combined scientific research results with its own frontline production practices. Waste pyrolysis technology and equipment have reached the international advanced level. The pyrolysis facilities are safe, environmentally friendly, efficient and productive. The quality of the products it produces is excellent.

Pyrolysis Plant Working Processes

Pyrolysis refers to the decomposition reaction of organic substances after reaching certain conditions, which is an irreversible reaction. Most organic compounds have thermal instability characteristics that decompose in high temperature anoxic environments. Macromolecular organic compounds will be converted into gaseous, liquid and solid components with relatively low molecular weight. Pyrolysis of organic solid waste generally produces high temperature oil gas, water vapor and solid products.


Pyrolysis Plant Working Processes

The main raw materials of the pyrolysis unit are clean waste tires, waste rubber, waste plastics, and sludge. After purchasing clean raw materials, it can be manually fed or automatically fed by related machines. The inside of the pyrolysis furnace can be continuously heated to 200~300 °C within 4 hours. At this time, the pyrolysis gas begins to produce steadily, and the temperature rises slowly in the next 5~8 hours. When the temperature reaches 450°C, the tyre pyrolysis has been considered almost done.

During the pyrolysis process, a large amount of flue gas is generated, and the flue gas flows into the steam distribution package through the pipeline, and the heavy oil sinks to the residual oil tank, then they are stored in the oil storage tank through the oil pump; the gaseous component enters the circulating water cooling system through the pipeline.

The flue gas cooled in the pipeline is divided into a liquid and a gas, wherein the gas is pyrolysis gas, and the liquid is a mixture of light oil and water. The liquid flows into the oil-water separator, and the separated light oil is stored in the oil tank through the oil pump. A small amount of oily wastewater is atomized and injected into the pyrolysis reactor combustion chamber as a fuel; the pyrolysis gas is piped to the pyrolysis reactor combustion chamber for use as a fuel.

Pyrolysis Plant Types & Technical Specifications

MoreGreen has three types of pyrolysis plants, which are Batch (also called Intermittent), Semi-Continuous, and Fully Continuous. The common points of the three pyrolysis facilities are high production efficiency, temperature control, stable safety performance, convenient operation and low pollution to the environment. Here are the differences between them:
  • Working Method:  The reactor of the Batch and Semi-Continuous pyrolysis equipment rotates under the working of the driving system, the raw material absorbs heat evenly in the reactor, and can avoid clogging. When the pyrolysis temperature is reached, waste begins to pyrolyze to produce oil gas; while the reactor of the Fully Continuous pyrolysis plant does not need to rotate, it uses the induced draft fan to heat the raw materials, and the raw material passes through the U-shaped path and is pyrolyzed into Fuel oil.
  • Raw Material Processing Capacity:  Batch and Semi-Continuous pyrolysis plants process 6-16 tons of waste per day. There are three models (MLJ-6, MLJ-10, MLB-16) for you to choose; Fully Continuous pyrolysis plants can be fed continuously so that the amount of waste disposal is higher than that of Batch and Semi-Continuous pyrolysis equipment. Similarly, Fully Continuous pyrolysis equipment is also available in three common models (MLL-30, MLL-40, MLL-50 ).
  • Automation:  The feeding and slagging process of Batch pyrolysis equipment need to be done manually; Semi-Continuous pyrolysis equipment can realize automatic feeding and simplify slagging; Batch pyrolysis plant can be upgraded to Semi-Continuous pyrolysis plant by installing pretreatment equipment to automate the production process. Fully Continuous pyrolysis equipment can realize fully automated feeding and slag by using the PLC control system, the whole process No human involvement is required.

Fully Continuous Pyrolysis Plant

Therefore, if you need to dispose of less than 16 tons of waste per day, Batch and Semi-Continuous pyrolysis plants will be a cost-effective option. And if you have more waste to process, you can choose the Fully Continuous pyrolysis plant, which can work 24 hours a day, improve productivity, and save you labour and costs.

We believe that you already know the main differences between the three types of pyrolysis plant, then we will use one table to give you a more intuitive representation of the parameters of these three types of equipment so that you can understand them further.

Final Products From Pyrolysis Plant

Pyrolysis is carried out using different raw materials, the chemical reaction mechanism is different, and the products produced are also different. Common waste raw materials include used tires, plastic, rubber waste, oil sludge.

Generally, the mass fraction of each component contained in the tyre tread rubber is approximately 55% to 60% of rubber, 30% to 33% of carbon black, 6% to 9% of organic additives, and 3% to 6% of inorganic additives. After the tire is pyrolyzed, the products are mainly pyrolysis fuel oil, non-condensable flammable gas and other storable energy sources, carbon black and steel wire.

Waste plastics generally refer to plastics such as PE, PP, and PVC. When these waste plastics are mixed together and pyrolyzed in high temperature and anoxic environment, they are generally decomposed into low molecular fuel oil, carbon black and industrial gases.

The sludge forms fuel oil, solid matter (such as sediment, mud cake, etc.) and industrial gases after the pyrolysis reaction.
