Oil Sludge Pyrolysis Plant

The oil sludge pyrolysis treatment equipment adopts a closed low-temperature pyrolysis process to convert oil sludge into reusable resources in an oxygen-free environment. The equipment is suitable for processing various types of oil sludge, including ground oil sludge, refinery oil sludge, and oil sludge at the bottom of storage tanks. Through efficient separation technology, the organic matter in the oil sludge can be converted into fuel oil, combustible gas and dry solid residue to maximize the utilization of resources.

Applicable raw materials

The equipment is suitable for the treatment of various oily wastes, including but not limited to:

• Oilfield drilling mud
• Refinery residue
• Oil sludge at the bottom of the tank
• Oil sludge leaked during transportation

Oil Sludge Pyrolysis Plant Process Flow

1. Pretreatment stage

Before pyrolysis, sludge usually needs to be pretreated to remove impurities, adjust water content and improve fluidity. This stage may include:

Dehydration: reduce the water content of sludge by natural sedimentation, centrifugal separation or hot air drying.

Crushing and screening: crush large pieces of sludge into appropriate particle size for subsequent processing.

Conditioning: add additives as needed to improve the physical properties of sludge.

2. Water evaporation stage (about 100–140°C)

In this stage, the sludge is heated to 100–140°C, the main purpose of which is to evaporate the water in it. Since the evaporation of water requires the absorption of a large amount of heat, this process is relatively slow, but it creates favorable conditions for the subsequent pyrolysis reaction.

3. Pyrolysis reaction stage (about 140–500°C)

When the temperature rises to 140–500°C, the organic matter in the sludge begins to undergo pyrolysis and decomposes into:

Fuel oil: mainly composed of light hydrocarbons, which can be used as industrial fuel or further refined.

Combustible gas: such as methane, hydrogen, etc., can be used to heat the pyrolysis furnace to achieve energy self-sufficiency.

Solid residue: mainly carbon black and inorganic matter, which can be used for building materials or other purposes.

This stage is the core of the entire pyrolysis process. The reaction rate and product distribution are affected by factors such as temperature, heating rate and raw material properties.

4. Condensation and separation stage

The oil and gas mixture produced by pyrolysis passes through the condensation system and is separated into liquid fuel oil and non-condensable combustible gas after cooling. The fuel oil is collected and stored, and the non-condensable gas can be used to heat the pyrolysis furnace to form a recycling of energy.

5. Tail gas treatment stage

To meet environmental protection requirements, the tail gas needs to undergo multi-stage purification treatment, including:

Dust removal: remove particulate matter to prevent air pollution.

Desulfurization and denitrification: reduce the emission of SO₂ and NOx to meet emission standards.

Activated carbon adsorption: remove organic volatiles to ensure that the tail gas meets emission standards.

Final Products and Applications of Oil Sludge Pyrolysis Plant

Fuel oil (45–55%): can be sold directly to refineries, steel mills, cement plants, etc., or further distilled and refined into diesel.

Dry solid slag (30–35%): can be used for building materials, roadbed fillers, etc., and meets environmental emission standards.

Combustible gas (8–10%): after purification, it can be used as equipment’s own heating fuel to reduce operating costs.
