Thermal Desorption Unit – TDU

Thermal desorption units are the equipment to heat the contaminated materials in a sealed reactor by enough high temperature for enough long time, to dry and vaporize the contaminants from it, and then obtain fuel oil finally.

Thermal desorption unit can be also called TDU, oil sludge pyrolysis plant, oil sludge treatment system, etc. See the description on wiki here.

Harmless treatment of oil sludge: the thermal desorption system is used for recycling different forms of crude oil sludge, including drill cuttings, tank bottom oil sludge, floor oil sludge, etc. After processed by the TDU system, the oil sludge will not pollute the environment any more.

Used as fuel in industries: after processed by the TDU plant, the crude oil sludge can be converted into fuel oil, which can be used as fuel in many industries, including cement plant, glass plant, power plants, steel plants, boiler plants, ceramic plants, etc.

1. Feeding of Oil Sludge

Collect all of the oil sludge together and then unload them to the workshop. Most of thermal desorption units are installed in the open air. And then use auto screw feeder to feed them into the pyrolysis reactor.

2. Treatment of Oil And Gas

Under the oxygen-free, high temperature and sealed environment, the three main components of oil sludge: oil, sludge, and water will be decomposed.

When the temperature rises to a certain degree, oil gas will come out. Thereinto, heavy particles in the gas will be liquefied into heavy oil and then dropped into the heavy oil tank; light particles in the gas will rise up and liquefied into light oil in the horizontal tube condenser and then also be reserved in the oil tank.

3. Discharging of Slag

The slag will be automatically collected during the process. The flue gas, before safe emission, may contain carbon and cause global warming, so they need to be cooled down at first and then go through de-dusting, washing, water spray, ceramic ring adsorption and activated carbon adsorption to remove the harmful matters in it. Finally, it will be discharged safely.

Note: we strongly recommend you choose the continuous pyrolysis plant because the oil sludge needs a pre-treatment before pyrolysis.

1. During the heating process, the pyrolysis reactor does not touch the open flame, which greatly improves the service life of the equipment.

2. The intermediate frequency power supply can fine-tune the input power power, to realize constant temperature heating, and improve the obtained fuel oil.

3. The TDU unit has realized the industrialized production, and the daily oil sludge processing capacity of a single machine can reach 32 tons; the operation of the central console greatly reduces the production cost and improves the working environment and labor intensity of workers.

4. The intermediate frequency power supply can be cut off in an instant, which greatly improves the safety performance of the equipment during operation. It is an innovation in the thermal desorption equipment and has good economic and social benefits.

5. The discharging of exhaust gas meets the international requirements, and there is no external discharge of waste water and waste oil residue water.

Profit of finished fuel oil

After processed by thermal desorption plant, the refined fuel oil can be sold directly or used as fuel oil in cement factory, glass factory or other industries. The products are favored by the market and bring considerable economic benefits.

Profit of oil residue

The soil residue produced after thermal desorption system can be landfilled or sold to brick factories to make bricks, or sold to oilfield companies for use as an oil well anti-slump agent.

Subsidies

Due to the relatively high hazard and serious pollution of oil sludge, the related petroleum department has given great financial support to the thermal desorption unit for drill cuttings. After the industrial park has obtained the relevant qualifications from the government’s environmental impact assessment department, the department will give a certain subsidy for each ton of oil sludge processed, and the subsidy is based on prevailing conditions.

Ecological Benefits

Oil sludge is polluting the earth seriously. The TDU unit can help solve the problem of environmental pollution, relieve the pressure of resource shortage and benefit the future generations.

Economic Benefits

You can enjoy subsidies from the government. Otherwise, you can also make money by crude oil sludge treatment. Through the above profit analysis table, you can see that the annual profit is very considerable.

Social Benefits

Investing in Beston thermal desorption units can create jobs for the local people. In addition to that, you will also enjoy the respect from others. Not only do you create jobs, but also improve the local environment.
