Oli sludge pyrolysis plant is an ideal solution for industrial oily waste treatment. It converts sludge into pyrolysis oil, water, and sand for reuse. What’s more, this machine is environmentally friendly and brings you considerable profits. In recent years, Beston Group has established cooperation with customers from all over the world in oil sludge treatment projects. This technology has huge potential in the fields of environmental protection and resource management. There is no doubt that sludge treatment plants will play an important role in future sustainable development.

Oil Sludge Pyrolysis Plant

Source of Oil Sludge

Oil sludge is a complex mixture of crude oil or refined oil mixed with soil or other media. However, oil in the sludge cannot be recovered directly. This may lead to environmental pollution. Oli sludge is one of the main pollutants in the petrochemical industry. The following are the sources of oil sludge and the problems involved in dealing with it.

Drilling Oily Waste

Drilling oily waste is waste generated in petroleum exploration and production, mainly including drilling mud, solid particles, drilling fluid residues and oil-bearing formation profile materials. These wastes are mixed during the drilling process to form a complex sludge that can contain large amounts of oil, gas and chemicals.


Crude Oil Extraction

Oil sludge in the crude oil extraction process mainly comes from surface treatment systems. This includes oil production wastewater treatment and wastewater purification. The resulting oily sludge has the characteristics of high oil content, high viscosity, fine particles, and difficulty in dehydration.


Oilfield Gathering and Transportation

The oil sludge from oilfield gathering and transportation mainly comes from oil tanks, settling tanks, sewage tanks, grease trap bottom sludge, and removed oily waste. When oil is in the tank, its heavy oil components are deposited at the bottom of the tank, forming oil sludge at the bottom of the tank.


Other Sources

Other sources of sludge mainly include the following. The steel smelting oil will pollute the surrounding soil. What’s more, the use of heavy oil hydrocarbons in shipbuilding and ship repair will pollute coastlines, river edges, and coastal areas. These contaminated soils contain oil sludge.


Limitations of Traditional Oli Sludge Treatment

The traditional oil sludge treatment cannot achieve reduction, resource utilization and harmlessness at the same time. Even incorrect handling can cause ecological harm. Therefore, it is very important to find more effective and environmentally friendly oil sludge treatment system. Pyrolysis plant has become a new option for oil sludge recycling.

Oli Sludge Treatment-Landfilling

  • Land resource consumption
  • Soil and groundwater pollution
  • Long-term maintenance
Oli Sludge Treatment-Incineration

  • Air pollution
  • Energy consumption
  • Greenhouse gas emissions
Oli Sludge Treatment-Centrifugation

  • Complex workflow
  • Few processing types
  • Low resource utilization

What is Oil Sludge Pyrolysis Plant?

When it comes to an oil sludge pyrolysis plant, it is designed for harmless treatment of industrial hazardous waste. Unlike scrap tyres and waste plastics recycling, this machine can achieve resource utilization and reduction while also making it harmless. Therefore, this kind of machine helps reduce the amount of waste and enables resource recovery. At the same time, the machine also reduces the environmental impact compared to traditional sludge disposal.

Key Components of Continuous Sludge Removal System

The key components of a continuous oil sludge pyrolysis plant typically include:


The pyrolysis reactor is the core component of the pyrolysis process. It is where the oil sludge is heated to high temperatures in the absence of oxygen, leading to the breakdown of organic materials into pyrolysis oil, gas, and solid residue.


First, the manifold buffers the oil and gas coming out of the main furnace as it enters the oil gallery condenser. In this way, the oil and gas enter the oil channel condenser evenly. In addition, it plays the role of separating gas and heavy oil.

Oil-Gas Condenser

The oil-gas condenser is responsible for cooling and condensing the pyrolysis gas into a liquid form, which is the pyrolysis oil. This component is crucial for separating the valuable pyrolysis oil from the gas mixture.

Slag Extractor

The sludge discharge screw extracts the solid residue. Then, after two water-cooled slag discharges, the solid residue enters the storage tank from the elevator. After cooling with circulating water in the tank, the solid residue is discharged.

Working Process Oil Sludge Pyrolysis Plant

The following is the process flow for treating sludge in a continuous machine. If you want to know the detailed process, you can refer to the video below. In addition, you can also visit our YouTube to learn more about pyrolysis projects.



A burner is required for the preheating process. Fuel can use energy such as natural gas. It takes 3-4 hours for the main furnace to preheat. When the main furnace is preheated to 300-350℃, the materials can be fed.


The feed system delivers the oil sludge to the main furnace. Oil sludge with a liquid content of less than 40% is recommended to be transported by a belt conveyor; oil sludge with a liquid content of 40%-60% is recommended to be transported by a shaftless screw; oil sludge with a liquid content of more than 75% needs to be transported by an oil sludge pump.


This is the most critical part in crude oil sludge treatment process. In a closed anoxic state, the reaction starts when the pyrolysis reaction temperature reaches about 450°C. At this time, the oil sludge undergoes thermal desorption process. The main furnace uses the hot air from the secondary combustion chamber for indirect heating.

Combustible Gas Collection

The process generates high-temperature combustible gas. The combustible gas circulates to the secondary combustion chamber, where it mixes with high-temperature hot air, heating the pyrolysis reactor.

Flue Gas Treatment

The high-temperature flue gas first enters the air distribution heat exchanger. During this process, the flue gas temperature is utilized to preheat the air. Subsequently, the flue gas enters the flue gas condenser. After cooling, impurities are absorbed through activated carbon. Finally, the flue gas undergoes desulfurization and denitrification treatment. Our advanced exhaust gas treatment system complies with the European Union emission standards.
