Thermal Desorption Unit For Oil Sludge Treatment
Thermal desorption unit for oil sludge treatment
The oil sludge thermal desorption unit(TDU), also called oil sludge thermal pyrolysis machine, independently developed by Henan Doing Group can process various types of oily sludge (HWO8 type) such as oilfield oily sludge, refinery oily sludge, tank bottom oily sludge, coal tar residue, oil-based drill cuttings, oil-contaminated waste, ground oily sludge, and coastline oily pollutants.
After treatment, pyrolytic mineral oil and ash residue are obtained. Pyrolytic mineral oil can be used as feedstock oil for refineries or directly as fuel oil. The oil content in the ash residue is less than 2%. Next, DOING Group will detail the processing technology and equipment advantages of the sludge thermal desorption unit.
Pyrolysis Technology of Oil Sludge Thermal Desorption Unit

1. Preliminary treatment: First, the sludge is treated to remove large solid phases, such as bricks and stones, and metals, and then the sludge is sent into the pyrolysis converter for high-temperature heating through an automatic feeder;
2. Dehydration: If the water content in the sludge is high, different types of sludge dehydration devices can be configured to achieve better drying and pyrolysis efficiency and effectiveness, reduce energy consumption, and ensure the safety of the entire sludge treatment and recovery process.
3. Feeding: Customizable configurations are available based on the specific form of oily sludge and the choice of equipment, including automatic conveyors, sludge pumps, etc.
4. Thermal Pyrolysis: The sludge is heated at high temperatures in a thermal pyrolysis reactor. When the temperature exceeds 100°C, water is gradually distilled out. When heated to above 180°C, mineral oil is gradually distilled out;
5. Cooling: After the distilled components are cooled and collected, they are condensed into liquid mineral oil and water; after subsequent water-oil separation treatment, the mineral oil is sent to the oil storage tank for storage;
6. Exhaust gas purification: The remaining part of the gas that cannot be cooled is directly recycled for heating secondary utilization after exhaust gas purification treatment; and the flue gas generated during the pyrolysis process can meet the emission standards after purification by the desulfurization tower + water film dust removal purification treatment;
7. Ash discharge: When the pyrolysis is completed and the temperature of the pyrolysis furnace drops to about 50°C, the rotation direction of the converter is changed to counterclockwise, and the dry distillation slag is discharged through the dry distillation slag discharger under the push of the reverse rotation of the converter.
