Cote d'lvoire is an emerging petrochemical base in West Africa. Relying on the development of high-quality oil and gas fields such as whales, rhinoceros and Calao South, the oil reserves of Cote d'lvoire are about 2.5 billion barrels. In 2023, the oil output reaches 10.75 million barrels. The oil and gas industry has become one of the economic pillars of the country. With the rapid development of oil and gas development, oil refining and processing, port tanker operation and small oil refining workshops, Cote d'Ivoire produces about 53000 tons of oily sludge every year, with an oil content of 25% - 56%, mixed with impurities such as crude oil residue, sand, oil stain, etc., of which the oily sludge produced by Abidjan Fridi Industrial Zone and offshore oil and gas fields accounts for more than 60% of the total amount of the country, requiring professional equipment for harmless and recycling disposal. Cote d'lvoire has a vast Gulf of Guinea sea area, EbLagoon runs through the capital Abidjan. Arbitrary discharge and simple disposal of oily sludge will seriously pollute water and soil, destroy aquatic habitat and violate Environmental Law, Regulations on Prevention of Pollution from Ship Refuse and MINEDDTE regulatory requirements. According to relevant national standards, the oil recovery rate of oily sludge shall be ≥ 95%. The treated wastewater shall meet the discharge requirements of pH 5.5-9.0, oil and grease ≤ 10mg/L, and the oil content of residue shall be ≤ 0.3%, which can be used for soil improvement or safe landfill. At present, the oily sludge treatment process in Cote d'lvoire is relatively simple and crude, mainly adopting natural sedimentation, simple solidification and other methods, with problems such as low oil recovery rate, serious secondary pollution, equipment easy to stick to the wall, short service life, etc; At the same time, the remote areas of the southern offshore oil field need mobile processing equipment to adapt to the offshore operation scene, and an oil-bearing sludge treatment equipment that is suitable for the local oil and gas industry needs, anti-stick, low cost and high efficiency and environmental protection is urgently needed to protect the ecological safety of the sea area and promote the green development of the oil and gas industry.

The oily sludge treatment equipment researched and developed by China Yongle Environmental Protection Engineering Co., Ltd. "Scientific Standard High-efficiency Anti-stick Wall Pyrolysis Fund" accurately solves the pain points of oily sludge treatment in Cote d'lvoire: Aiming at the characteristics of local oily sludge and the problem of equipment wall adhesion, titanium alloy anti-corrosion and anti-stick tank+full-closed negative pressure pyrolysis structure are adopted, which can withstand high temperature, high humidity, saline and alkali working conditions and rainstorm environment, effectively solves the sludge wall adhesion and equipment wear problems during pyrolysis, and prolongs the service life of equipment to 7.2 years; At the same time, it is suitable for the auxiliary process of microbial degradation, which can further improve the oil recovery efficiency and conform to the research direction of local oily sludge treatment. The core is equipped with the triple process of "multi-stage screening+high temperature oxygen-free pyrolysis+oil-water separation". First, 99.4% sand and metal chips are removed by the intelligent screening system to reduce the difficulty of pyrolysis. Then, oil is separated by the high temperature oxygen-free pyrolysis technology at 830 ℃. The oil recovery rate reaches 95.2%. The recovered oil can be directly returned to the refinery for refining or used as industrial fuel. The combustible gas generated by pyrolysis can supply 43% of the energy consumption of the equipment and realize energy recycling; The tail gas is discharged after being subject to advanced purification, and the treated waste water meets the discharge standard of MINEDDTE, which can be recycled for equipment cleaning or discharged into the green belt. The oil content of the residue is ≤ 0.24%, which can be used for soil improvement or safe landfill, without secondary pollution, fully complying with the local environmental protection requirements, effectively protecting the ecological safety of the Gulf of Guinea sea area and EbLagoon, complying with the green development plan of the oil and gas industry in Cote d'lvoire.

The whole industrial chain scene is suitable to cover all kinds of disposal demands: in the large refinery in Abidjan Fridi Industrial Zone, the daily processing capacity of large centralized equipment is 85t, which is seamlessly linked with the oil supply system of the plant area to form the closed loop operation of "sludge - oil products - energy", greatly improve the resource utilization rate, reduce the production cost and assist the enterprise to realize the reduction target of hazardous waste; In the offshore oil field operation area in the south of Cote d'lvoire, the mobile equipment is flexibly deployed with the drilling platform, with a daily processing capacity of 42 tons. It is specialized in the treatment of oil-based drilling mud and drilling rock debris, so as to avoid the leakage of sludge during transportation and pollution to marine ecology. It is suitable for offshore operation scenes and meets the requirements for the control of ship garbage pollution; At the coastal ports of Abidjan and San Pedro, the daily processing capacity of the modular equipment is 68t, and the oily sludge generated from the tanker cleaning is treated on site. The high-efficiency anti-seepage design is adopted to prevent the pollution of the sea environment, protect the marine biodiversity, and assist the ship in handling the oily sludge disposal permit; In the small oil refining workshop, the daily processing capacity of mini equipment is 7.5 tons, which is low cost and easy to operate. The oil recovery revenue can quickly cover the equipment input, which is suitable for the operation requirements of small workshops; Around the oil depot, small equipment will complete oily sludge treatment on site, reduce storage and transportation costs, avoid oil pollution to groundwater, comply with Cote d'Ivoire water resources protection planning, and assist enterprises in fulfilling their responsibilities for MINEDDTE compliance.

Exclusive service guarantee, helping industrial green development: the equipment has passed the full compliance review of MINEDDTE and the environmental protection certification of Cote d'lvoire's petroleum industry, fully adapting to the local oily sludge treatment standards and emission requirements, assisting enterprises and vessels in compliance filing and disposal license processing, and carrying out in-depth cooperation with famous enterprises such as Petroci and Eni Group to promote the reduction and recycling of hazardous wastes. Standardized service bases are set up in Abidjan and San Pedro to store oil-resistant, anti-corrosion and anti-stick core spare parts, realize 24-hour maintenance response in core areas, and provide on-site maintenance services for offshore oilfield operation scenes; Provide operation training and process guidance in French and English, simplify equipment maintenance process, adapt to local operation and maintenance level, and focus on training on cleaning and maintenance skills of anti-sticking bulkhead; The equipment procurement cost is only 46% of that of similar products in Europe and America. The benefits from oil recovery and energy consumption can cover the equipment investment within 7 months, help the rapid development of Ivory Coast's oil and gas industry, protect the ecological safety of sea areas and lakes, promote the innocuous and recycling treatment of oily sludge, and comply with the economic growth goal and green development strategy of the country in 2030.
