Sources and Hazards of Oil Sludge
In various stages of oil exploration, production, storage and transportation, and refining, large quantities of oily sludge are produced each year. The oil sludge contains 5% to 50% petroleum and pollutants such as polycyclic aromatic hydrocarbons and heavy metals. This makes it toxic and flammable. It significantly pollutes the air, soil, and water resources, posing severe threats to the ecological environment and human health. There exist considerable challenges to its disposal.

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
Treatment Results Analysis of Oil Sludge Pyrolysis Machine
01 Test Report of Pyrolized Oil Sludge
Test Process: Heating a 210g oil sludge sample to 242°C.
Test Result: 67.14% of the oil sludge is converted to heavy oil, 25.24% remains as oil sludge, and 7.62% is lost.
Analysis:
- A 67.14% yield of heavy oil is an ideal pyrolysis outcome. The converted heavy oil has broad applications as fuel or raw material for other processes.
- A 25.24% yield of sludge is within a reasonable range. Sludge is a more stable and less hazardous substance compared to oil sludge.
- A 7.62% loss of oil sludge is acceptable. The loss may be due to the formation of volatile gases (e.g., combustible gas) and light hydrocarbons.
- The pH value of the pyrolysis residue is between 8 and 9, slightly alkaline. This is an ideal result, indicating that the residue is not hazardous.
Conclusion: Oil sludge pyrolysis plant helps produce heavy oil and stabilize oil sludge.
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:
- Residual oil ratio: The petroleum hydrocarbon content in the final residue after oil sludge pyrolysis is 293 mg/kg. This is within the national standard range. For instance, the United States allows petroleum hydrocarbon limits in different scenarios to range from 4,000 to 20,000 mg/kg.
- Heavy Metal Content: The heavy metal content in the final residue meets or is below the national standards for corresponding elements.
Conclusion: Oil sludge pyrolysis equipment recovers oil and reduces heavy metal content. It is an effective harmless and resource-recycling solution.
Profit Source Analysis of Oil Sludge Pyrolysis Plant
Charging for Hazardous Waste Disposal
Disposal fees depend on waste volume, type, and local environmental regulations. For example, a waste management company in Nigeria charges $200 per ton for processing oil sludge with pyrolysis technology. In the long term, this can fully cover the oil sludge pyrolysis plant cost.
Subsidies from Petroleum Departments
Due to the high hazard and severe pollution caused by oil sludge, petroleum departments typically provide economic subsidies for pyrolysis treatment of oil sludge. The amount of subsidy depends on local policies.
Profit from Regenerated Oil
Fuel sales units or refineries may have interest in the fuel oil produced from pyrolysis of oil sludge. This can generate significant economic benefits.
Profit from Sand Sales
The sand produced from oil sludge pyrolysis machine can be used in landfills, sold to brick factories for brick production, or sold to oil companies as an anti-collapse agent for oil wells.

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.
