Thermal Desorption Unit

A thermal desorption unit is used to treat a range of oily substances. This equipment can convert these materials into oil and solids. Customers can benefit from the final oil. Solid slag from the TDU could be disposed of harmlessly. Beston equipment recycles these materials safely, efficiently, and pollution-free. If you are interested, please contact us.

Good-quality Beston Thermal Desorption Unit for Treating Oil Sludge

Which Industries Generate Oil Sludge?

Oil-containing sludge is a composite material consisting of oil, water, mud, heavy metals, and other particulate matter. Its sources span across multiple industries:

Oilfield Development Industry Drilling cuttings sludge, produced fluid sediments, oil-water separator sludge, etc.;

Petroleum Refining Industry Desalination sludge, heavy oil hydrocracking sludge, catalytic pyrolysis sludge, etc.;

Petrochemical Industry Ethylene coke sludge, polypropylene coke sludge, etc.;

Mining industry Mechanical fuel oil sludge, mining oil sludge, etc.;

Shipbuilding industry Ship fuel oil sludge, shipyard oil sludge, etc.

Industries Generate Waste Oil Sludge for Thermal Desorption

Why is It Necessary to Treat Oil Sludge?

Environmental Protection

The pollutants in oil sludge, such as oil and heavy metals, can contaminate soil, water bodies, and the atmosphere. This negatively impacts the health of people living in the surrounding areas.

Reducing Space Consumption

Oil sludge is a solid waste that requires a certain amount of space for storage and treatment. Storing oil sludge can lead to the waste of land resources and diminish the land’s value for other purposes.

Reducing the Risk of Accidents

Oil sludge is viscous and prone to block pipelines. This causes production accidents. Additionally, its flammability can lead to fires. And it results in property damage and casualties.

Resource Recycling

Oil and other valuable substances in oil sludge can be reclaimed through appropriate treatment techniques. This helps reduce resource wastage and lowers production costs in the industry.

Necessary to Treat Oil Sludge by TDU Unit

What is Thermal Desorption Unit?

Beston thermal desorption equipment separates oil and water from oily solid materials in a high temperature and oxygen-free environment. When oil sludge undergoes a reaction in the Beston waste pyrolysis equipment, the temperature ranges between 280 to 350 degrees Celsius. After oil sludge is treated, the exhaust gas meets emission standards after being purified by the de-dusting system.

Beston thermal desorption machine is mainly composed of feeding system, pyrolysis system, combustible gas recovery system, discharging system and de-dusting system. Customers can customize their own thermal desorption production line according to their needs. The following 3D image shows the structure of continuous TDU.

What is Thermal Desorption Unit Process?

Step 1. Feeding Process

Oil sludge with a liquid content below 40% is recommended to be transported by belt conveyor;

When a liquid content is between 40% and 60%, we recommend use shaftless screw conveyor to transport oil sludge;

Oil sludge with a liquid content above 75% requires transportation by oil sludge pump.

Step 2. Thermal Desorption Process

Heat the thermal furnace. The pyrolysis temperature reaches between 450 degrees and 500 degrees. The oil gas is generated. It enters into the condenser. Then large part is liquified into pyrolysis oil. During this process, oily sludge is decomposed into oil, non-condensable syn-gas, emission gas and solid carbon black. These things are collected separately for recycling.

We offer two material options for the main furnace: Q345R and 304 stainless steel. We recommend choosing 304 which has longer lifespan.

Step 3. Syn-gas Recycling & Dedusting Process

The non-condensable gas enters the combustion system after being water-sealed and desulphurized. The generated hot emission gas enters the de-dusting tower and the condenser under the action of the induced draft fan. The exhaust gas reaches the emission standard after purification and cooling.

Step 4. Discharging Process

The discharging system is used to transport solid residues into the tank. The solid components such as carbon slag are cooled down by the water-cooling screw discharger in the waste pyrolysis process. Finally, its temperature is below 30 degrees.
