Facing the increasingly severe problem of recycling industrial oily hazardous waste, thermal desorption unit(TDU) provides a sustainable solution. By utilizing a controlled heating process, TDU effectively breaks down oil sludge. Thereby, the machine enables the recovery of valuable resources such as fuel oil and syngas. In general, thermal desorption unit not only meets the urgent need for effective waste management but also contributes to the sustainable development of the crude oil industry.

Superiority of Thermal Desorption Technology

Thermal desorption is an environmental pollution control technology. It works by heating oily hazardous waste, also known as oil sludge, to volatilize organic matter from the solid matrix. Since it also involves high-temperature pyrolysis of oil sludge in a microaerobic environment, this technology is also called oil sludge pyrolysis. The multiple superiorities of this technology make it widely used in oily sludge recycling.

Extensive Recycling Range

Thermal desorption technology has strong applicability. This technology has no special requirements for the water content, oil content, and solid content of oily waste. Therefore, it can handle waste generated from various stages of crude oil extraction, processing, and refining wastewater treatment.

01

Comprehensive Resource Utilization

This technology can utilize the resources of the end product. The oil, syngas, and solid residues produced through thermal desorption processes have a wide range of applications. They are effectively used in energy production, chemical industry, and other fields to achieve sustainable use of resources.

02

Efficient Harmless Treatment

This technology completely decomposes organic matter in oil sludge. Therefore, it can reduce the accumulation of waste on a large scale. Additionally, it converts waste into harmless products. This harmless treatment method can effectively reduce the risks caused by waste to the environment and human health.

03

Significant Environmental Benefit

Due to precise parameter control, thermal desorption can maximize the utilization of energy. In addition, unlike traditional treatment methods, this technology does not require the addition of additional chemicals. Therefore, this reduces secondary contamination from the chemical treatment process.

How Does Thermal Desorption Unit Work?

01

Raw Material Conveying

  • Liquid content below 40%: belt conveyor;
  • Liquid content 40%-60%: shaftless spiral;
  • Liquid content rate above 75%: sludge pump;
02

Thermal Desorption

The entire reaction environment is microaerobic and high temperature. The reaction temperature reaches 200-450 degrees Celsius in the pyrolysis machinery. During the thermal desorption process, the organic matter in the oil sludge begins to thermally decompose. Eventually, high-temperature oil gas and solid residues are formed.

03

Oil Gas Condensing

  • Oil gas first passes through the manifold to separate the heavy oil gas.
  • The remaining oil gas then enters the condenser.
  • The condensable oil gas condenses into oil through heat exchange and then falls into the oil storage tank.
  • The non-condensable syngas is purified by a water seal and provides a heat source for the thermal desorption process.
04

Solid Discharging

In cooperation with the reactor, the screw extractor discharges the solid residue. In addition, the waste-cooled screw extractor can quickly cool the temperature of solid residues for easy collection.

05

Emission Gas Treatment

The remaining waste gas from the reaction passes through the cooling tower and dust removal tower for cooling and dust removal. After reaching the emission standards, the exhaust gas is discharged through the chimney. If your project location implements high emission standards, we provide high-end exhaust gas treatment systems. The waste gas treated by this system can meet EU standards.

  • The main furnace reducer is equipped with a protective cover. The control system is equipped with a security alarm system;
  • Before and after the reaction, the nitrogen system (optional) can replace the air/syngas in the furnace to prevent the flash explosion.
01

Eco-friendly Emissions

  • Combustion exhaust gas is treated by environmental protection facilities to meet emission standards;
  • The slag discharging system is designed with water-cooled slag discharging method to reduce dust pollution.
02

Efficient Reaction

  • Make full use of the syngas generated by the reactor for secondary combustion to reduce energy consumption;
  • Coke residue hinders the thermal desorption reaction. The equipment applies anti-coking technology to improve production efficiency.
03

Intelligent Operation

  • PLC control system and DCS (Distributed Control System) are optional. They improve control efficiency and save manpower;
  • IoT control system is optional. This enables real-time online monitoring of machine operations on the mobile terminal.
04

Factors Affecting Thermal Desorption Plant Cost

There are many factors that influence the cost of a machine. They may involve configuration planning and machine manufacturing. If customers want a more reasonable TDU cost, a suitable solution is essential. Therefore, if you are interested in investing, please contact Beston Group. Our project consultants will comprehensively discuss the feasibility of the project with you.

01

Machine Capacity

Larger equipment typically requires more raw materials and components than smaller equipment. Therefore, the larger the machine capacity, the cost of required production consumables and parts will also increase accordingly.
02

Operating Mode

The continuous operation mode is more advanced than the skid-mounted and intermittent modes, but it also means higher investment costs. Continuous operation requires more complex automation equipment and control systems, which increase thermal desorption unit price.
03

Main Furnace Material

Main furnaces made of different materials have different corrosion resistance and service life. Generally speaking, higher-quality materials (such as 310S stainless steel) are more resistant to corrosion but are also more expensive.
04

Component Options

The selection of components such as feed systems, high-end off-gas treatment, and distillation equipment will affect the performance and functionality of the equipment. More and more complex component options will increase the cost of the equipment.
