Combination Process Increases Oil Sludge Pyrolysis Plant Efficiency by 200%
Thermal Washing+Decanter Centrifuge
This process mixes oil sludge with hot water and emulsifiers. Then, it heats and emulsifies the mixture, and impurities are washed away. After that, centrifugal force separates oil, water, and solids, and the cleaned residues are ready for pyrolysis conversion.
Pyrolysis
Oil sludge pyrolysis process converts high-purity oil sludge into fuel oil, syngas, and non-hazardous residue. Due to the reduction of impurities in oil sludge, the reaction becomes more efficient. Thus, it reduces the hazards of oil sludge exposure to environment.

Oil Sludge Pyrolysis Project – Customer Practices
Oil Sludge Pyrolysis Process – Reduction & Resourcing & Harmless Disposal
01 Feeding
Input oil sludge into pyrolysis reactor. Select the appropriate transportation mode according to the liquid content of oil sludge.
- below 40% – belt conveyor
- between 40% – 60% – shaftless screw conveyors
- above 75% – oil sludge pumps.
02 Pyrolysis
Pyrolysis reactor always maintains a low-oxygen and sealed environment. With the combustion chamber heating the reactor, the temperature rises. At 200-450℃, oil gas will come out. Due to the absence of air, the process effectively eliminates the generation of dioxins, and NOx, and produces almost no H2S or SO2.
03 Oil Gas Condensation
- Heavy particles in the oil gas will be liquefied into heavy oil and then dropped into the heavy oil tank.
- Light particles in the gas will rise and be liquefied into light oil in the vertical condenser and then also be reserved in the oil tank.
- The combustible gas will be desulfurated and cleaned in hydroseal and then come into the combustor as fuel.
04 Slag Collection
In this process, oil sludge pyrolysis plant cool the solid slag produced from pyrolysis through water-cooling heat exchange and then automatically collects it.
05 Flue Gas Treatment

02 Test Report of Residues from Oil Sludge Pyrolysis
Different countries have different standards for the disposal of oil sludge pyrolysis residues. Moreover, oil sludge pyrolysis residues used in different industries’ landfill disposal (e.g. agricultural land, building land) can also make standards different. Therefore, this report is for simple reference only.
Test Analysis:
- Typical EPA TPH screening range (C10–C40): 96–440 mg/kg
- TPH in oil sludge after Beston’s pyrolysis treatment: 293 mg/kg. This is within the national standard range.
Conclusion: After pyrolysis treatment, the total petroleum hydrocarbon (TPH) content of the oil sludge is significantly reduced, falling within the commonly referenced EPA risk-based Regional Screening Levels (RSLs) used for soil evaluation.
Profit Source Analysis of Oil Sludge Pyrolysis Plant

2 Leading Ecological Benefits of Oil Sludge Pyrolysis
Soil Contamination Remediation
Oil sludge pyrolysis plant helps remove harmful oil-based substances from contaminated soil. The high temperatures during the pyrolysis process can break down hazardous components in the oil sludge, such as heavy metals and volatile organic compounds, thereby reducing their persistent pollution in the soil. This contributes to the remediation of contaminated soil.
Mitigate Water Pollution
Oil sludge contains large amounts of oil and toxic substances, and direct discharge can lead to water pollution. Oil sludge pyrolysis effectively treats the sludge, reducing the risk of water contamination at the source and protecting the quality of groundwater and surface water.
