Oil Sludge Harmless Treatment Project in Africa: Green Transition from Incineration to Pyrolysis

1. Project Background

Customer Industry

The customer is a medium-sized solid waste recycling and management company in West Africa.

Challenges

Before introducing the new solution, the customer mainly adopted the traditional incineration method, facing difficulties:

• Severe environmental pollution: Black smoke and harmful gas emissions from incineration lead to environmental regulatory pressure.
• Harsh operating environment: High temperature, dust and odor pose high health risks to operators.

Core Goals

The customer clearly put forward the transformation demand, seeking a TDU system that ensures environmental compliance and stable operation.

2. Solution and Project Details

3. 43 Days On-site Guidance: Installation/Comissioning/Training

Week 1: Construction Coordination

• Site & Personnel: Finalized foundation setting-out and equipment positioning; clarified the installation plan and optimized manpower to ensure the project remains on schedule.
• Pre-assembly: Synchronized the ground welding and assembly of key components (condensers, etc.) to improve subsequent installation efficiency.

Week 2: Module Assembly

• Component Assembly: Continue assembly and welding of multiple parts, including belt conveyors, slag screws, flue condensers, etc.
• Goods Inspection & Procurement: Identified damaged or missing parts early and coordinated local procurement with the client to avoid schedule delays caused by cross-border replenishment.

Week 3: High-precision Hoisting

• Core Equipment Hoisting: Completed hoisting of pyrolysis reactor, casing, feeding platform, oil storage tank, etc.
• Pre-assembly: Continue assembly and welding of components including belt conveyors, spray towers and water pump supports.

Week 4: Pipeline Construction

• Pipeline Construction: Completed construction of oil-gas pipelines, flue gas pipelines, fuel gas pipelines and oxygen supply fan pipelines.
• Site Coordination: Supervised the client and construction team to rectify delayed works; repaired deformation at the bottom of the oil-gas condenser caused by unloading.

Week 5: Installation & Welding Works

• Component Installation: Completed installation of burners, air compressors, instruments, tank connections, furnace doors, slag discharge parts, etc.
• Auxiliary Welding: Carried out tack welding and full welding of spray towers, pipelines, ladders, reducers, etc.
• Electrical Preparation: Cables arrived on site; completed fabrication of electric control cabinet supports and coordinated electricians for on-site construction.

Week 6: Final Installation & Commissioning

• Complete Machine Installation & No-Load Test Run: Complete overall equipment installation, conduct no-load testing, and adjust system based on test results.
• Load Test Run & Operator Training: Complete 15 tons of oil sludge trial run, produce oil products; conduct operator training for the client to ensure independent operation capability.

4. Project Value & Results

• Stable & Sustainable Operation: Achieved an increase in processing capacity while effectively reducing pollutant emissions and enhancing workplace safety.
• Optimized Cost Control: Obtained pyrolysis oil for use as fuel, which substantially reduces energy procurement expenses and overall operational costs.
• Enhanced Corporate Brand Value: By actively fulfilling environmental responsibilities, the company has boosted its reputation among local authorities and the community, fostering a favorable external environment for long-term growth.
