Oil sludge (containing poly-cyclic aromatic hydrocarbons and heavy metals) has been recognized as hazardous waste and will pollute soil, air and water sources if improperly disposed of.
Dripping Oil Sludge
Refinery Sludge
Oil-contaminated Soil
Oily Cuttings
Tank Bottom Oil Sludge
As of 2025, the global annual production of oily sludge has exceeded 10 million tons, increasing at an annual growth rate of 7.2%.
The EU requires that the harmless treatment rate of oil sludge should reach above 95%.
TDU/Pyrolysis technology is listed as a core process, which has both harmlessness and resource value.
The actual global disposal rate for oil
sludge is merely17.45%
The core competitive advantage of our Oil Sludge Pyrolysis Plants lies in its proprietary closed-loop, high-precision system design. This innovation directly and comprehensively resolves two pervasive industry pain points: low processing efficiency and reactor coking.

Energy Value: alternative fuel for industry & diesel generators.
Industry: Ships, boilers, furnaces, kilns, etc.
The Beston TDU Process is an highly efficient, environmentally friendly closed-loop system for oil sludge pyrolysis.
Three feeding methods for different oil sludge liquid contents:
Below liquid content 40% : belt conveyor; 40%-60% liquid content: shaftless spiral; More than 75% liquid content: sludge pump.
Thermal desorption reaction occurs in a high-temperature micro-aerobic reaction environment. During the reaction, oil sludge undergoes the following changes in thermal desorption equipment:
Under high-temperature conditions, long-chain hydrocarbons in oil sludge are broken into small molecular hydrocarbons. Condensable components in the oil gas can be cooled through the condenser to form fuel oil. Non-condensable oil gas is purified by water sealing to form syngas, which provide energy for the reactor.
The high-temperature exhaust gas passes through the flue condenser and spray tower for cooling and dust removal. In addition, we provide high-end exhaust gas treatment systems, including electrostatic dust removal, activated carbon dust removal, and desulfurization and denitrification treatment. The flue gas emitted by high-end exhaust gas treatment can meet EU standards.
Fuel oil is converted into higher quality non-standard diesel through oil distillation equipment. With this equipment, fuel oil goes through the following stages:
Distillation: heating the fuel oil and separating components with different boiling points.
Condensation: cooling and liquefying the evaporated components.
Acid & alkali washing: removing acidic and alkaline impurities and improving oil quality.
Some solid substances in oil sludge cannot participate in thermal desorption and eventually form solid residues. The solid residue is discharged through the water-cooled screw conveyor.
