Common Pyrolysis or Catalytic Pyrolysis: Choose Your Technical Solution
Pyrolysis is a thermal decomposition process that occurs at high temperatures in the absence of oxygen. Beston Group offers 2 pyrolysis technology solutions (thermal desorption unit) for efficiently treating oil sludge with varying characteristics. Welcome contact us for a detailed consultation.
Oil Sludge Pyrolysis Plant
Common Pyrolysis
Applicable Materials: oil sludge with a high oil content.
Benefits: Achieve harmless disposal and volume reduction of oil sludge.
Catalytic Pyrolysis
Applicable Materials: oil sludge with high wax content.
Benefits: Prevent wax buildup in pipelines, reducing safety risks during production; facilitate the harmless disposal and reduction of waste.
Feedstock for Pyrolysis: Where Does Oil Sludge Come from?
The petroleum industry, vital to the global economy, also poses significant environmental challenges, particularly in oil sludge generation. This complex mixture contains harmful substances (heavy metals, PCBs, etc.), and some crude oil. Its improper handling can lead to severe soil and water pollution. Oil sludge is produced at various stages of petroleum economic activities, including:
Oil Exploration and Production
Types: oil-based cuttings, operational sludge, and landed sludge.
Formation: During the drilling process, waste like drilling mud, solid particles, drilling fluid residues and oil-bearing formation profile materials are mixed to form complex sludge.
Oilfield Gathering and Transportation
Types: oil-based cuttings, tankbottom sludge.
Formation: When oil is stored in tanks, heavy oil particles settle at the bottom, forming oil sludge. Common deposition locations include the bottoms of oil tanks, sedimentation ponds, sewage tanks, and grease traps.
Formation: These wastes are byproducts of the treatment and separation processes during oil refining. These wastes often contain oil residues, chemicals, and other impurities.
Oil Spill Accident
Formation: In the event of an oil spill, either from offshore rigs, pipelines, or storage facilities, large amounts of oil can mix with water, soil, and debris, forming a thick, oily sludge. This oil sludge can spread across vast areas and pose significant environmental hazards.
How Does Oil Sludge Pyrolysis Plant Achieve Harmless Treatment?
01 Feeding
Open reactor door and connect hydraulic feeder to it. Under the pressure of hydraulic feeder, oil sludge goes to reactor. Remove hydraulic feeder after feeding and close and lock the door tightly.
Note: Choose the appropriate feeder according to the state of the oil sludge.
Oil Sludge Moisture Content
Recommended Feeding Method
Below 40%
Belt Conveyor
40%-60%
Shaftless Screw Conveyor
Above 75%
Oil Sludge Pump
02 Preheating and Pyrolysis
Start the main reactor rotation and preheat with your own fuel. When temperature reaches about 110℃ after 2-3h, it begins to produce oil gas and water. The oil gas enters manifold through the first screw, under the action of gravity, the heavy oil slag falls to the screw and is pushed to the reactor for further pyrolysis.
03 Oil Gas Condensation and Pyrolysis Gas Recycling
Light oil gas enters vertical tube condenser. Under the action of water cooling, the high-temperature oil gas is condensed into liquid oil and stored in the oil storage tank.
The uncondensed pyrolysis combustible gas enters the hydroseal for purification. It then enters the furnace for combustion and utilization in order to save fuel. The excess pyrolysis gas enters the exhaust chamber for combustion and emission treatment.
04 Flue Gas Dedusting
The high temperature flue gas from the main reactor enters the flue condenser for cooling treatment. Then it goes to the spray tower for spraying dust removal, discharging through the chimney to the atmosphere.
05 Water-cooling Discharging
Close the burners after the reaction, the main reactor and the draft fan still operate normally. After 7-8h of natural cooling, the slag can be discharged by auto screw discharger and water-cooling discharger.
Final Products of Oil Sludge Pyrolysis Plant
Pyrolysis Oil
Pyrolysis oil consists mainly of hydrocarbons derived from thermally cracking organic matter in oil sludge. Its key fractions include:
Light oil: Used as fuel, industrial solvent, or refined into naphtha for steam cracking (producing ethylene and propylene).
Non-standard diesel: Applied where fuel quality requirements are low, such as construction machinery, ships, boilers, and power generation equipment.
Gasoline blending components: Added to commercial gasoline to boost octane ratings.
Sand
Sand is a by-product formed from the minerals and impurities in the oil sludge during pyrolysis. It can be applied in such way:
used in landfills, sold to brick factories for brick production;
sold to oil companies as an anti-collapse agent for oil wells.
Combustible Gas
The combustible gas produced includes methane (CH₄), carbon monoxide (CO), hydrogen (H₂), and other light hydrocarbons. These gases come from the decomposition of organic substances like oils and fats in the oil sludge, which break down into smaller molecules under high temperatures.
Usually directly purified and reused to provide heat to the oil sludge pyrolysis plant.
Possible Profit Sources from Oil Sludge Pyrolysis Plant
Selling Pyrolysis Products
Potential Buyers: Oil refineries, construction companies, etc.
Profit Income: Dependent on the market price of pyrolysis products.
Reason: Pyrolysis products have wide industrial applications. The potential buyers are willing to purchase these cost-effective industrial materials.
Government Economic Subsidies
Potential Source: Policy subsidies and tax incentives
Profit Income: Subsidy amounts vary by specific region and policy.
Reason: Governments around the world encourage businesses to prioritize waste management through financial subsidies. Oil sludge pyrolysis become one focus due to its environmental benefits.
Charging for Hazardous Waste Disposal
Potential Target: Entities generating oil sludge waste, such as oil drilling companies and chemical plants.
Profit Income: 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.
Reason: Oil sludge is classified as hazardous waste, and many countries have strict regulations regarding its disposal. Companies can charge waste-generating entities for the disposal process. As environmental regulations become more stringent, the demand for hazardous waste disposal services is increasing, particularly from industries like oil and chemicals that generate large quantities of waste.
