The oil and mining industry in West Africa is thriving, with large-scale projects such as the Niger Delta oil field in Nigeria and the Simandou iron mine in Guinea generating over 800000 tons of oily sludge annually in the region, mainly from oil field extraction, heavy oil power plants, and port oil tank cleaning. These oily sludge are complex in composition, containing not only hydrocarbons such as crude oil and diesel, but also impurities such as iron ore dust and sediment. In high temperature and rainy environments, they are easily dispersed to farmland and water sources with rainwater, causing devastating damage to agriculture and fisheries in countries such as Nigeria and Gabon. In 2024, ECOWAS issued the "Convention on the Management of Hazardous Waste", which explicitly requires that the oil recovery rate of oily sludge must not be less than 75%, and harmless disposal must be achieved. Traditional landfill methods have been completely banned, and efficient treatment equipment has become a must-have for energy and mining enterprises.

Based on the characteristics of oily sludge in West Africa, China Yongle Environmental Protection Engineering has specially developed an integrated equipment for "pretreatment pyrolysis deep separation". In the pretreatment stage, the integrated module of "cyclone sand removal+centrifugal dewatering" is used to remove more than 90% of sand and gravel impurities, and then reduce the sludge moisture content to below 25%; The core pyrolysis system adopts intelligent temperature control technology to stabilize the temperature at 420 ℃, avoiding excessive cracking of oil and achieving an oil recovery rate of over 83%. The recovered oil can be directly supplied to mining power plants or local refineries, achieving resource recycling. The equipment is equipped with wear-resistant alloy conveying components and anti-corrosion reaction chambers, optimized for the high wear characteristics of oily sludge from Guinea iron ore, ensuring a continuous operating life of over 18 months.

Accurate adaptation to the entire industry chain scenario: In the Niger Delta oilfield in Nigeria, mobile equipment can be deployed nearby around drilling platforms, with a daily processing capacity of 8 tons, avoiding the risk of leakage caused by long-distance transportation of oily sludge. The separated oil can be directly transported back to the production system, and the harmless residue can be used to lay temporary roads; In the heavy oil power plant of the Simandou iron mine in Guinea, modular equipment is seamlessly integrated with the power plant drainage system to achieve daily cleaning of oily sludge, and the processing scale can be flexibly adjusted according to the power plant load; In ports such as Lome in Togo and Cotonou in Benin, small equipment covers an area of only 70 square meters and supports rapid deployment of containers. It is specifically designed to handle oily sludge generated from oil tank cleaning and recycle oil products for use in port machinery.

We rely on our rich experience in African projects to provide customized services: optimizing oil recovery parameters for oilfield areas, providing technical guidance for residue resource utilization for mining areas, and assisting clients in completing compliance filings with local environmental protection departments throughout the process. Set up service centers in Lagos, Nigeria and Libreville, Gabon to reserve specialized spare parts suitable for tropical climates, and cooperate with local logistics companies to ensure fast delivery of spare parts. There is no secondary pollution during the operation of the equipment, and the exhaust gas is discharged after multiple purification treatments. All indicators are better than West African environmental standards, and it can be safely deployed around oil fields, mining areas, and ports. Looking forward to collaborating with West African oil companies, mining giants, and environmental organizations to provide efficient and compliant oily sludge treatment solutions, safeguard regional energy development and ecological security, and support sustainable industrial development.

Yongle Environmental Protection is mainly engaged in the research and development, production and sales of complete sets of technical equipment for organic solid waste disposal and comprehensive utilization. Production and manufacturing, domestic waste treatment equipment, tire pyrolysis equipment, medical waste disposal equipment, hazardous waste disposal equipment, and achieve efficient and comprehensive utilization of resources through independently developed low-temperature anaerobic pyrolysis equipment technology solutions.
