Congo (Brazzaville) and Congo (Kinshasa) are important oil and gas producing countries in Central Africa. The oil fields along the Congo River, the Brazzaville refinery, and the Blackhorn Port oil depot produce about 200000 tons of oily sludge annually, with an oil content of 38% -55%, mixed with impurities such as crude oil residue, sand particles, and plant residues. If the oily sludge is directly discharged, it will seriously pollute the Congo River - the annual output value of the fishing industry in the river basin exceeds 1.8 billion US dollars, supporting the livelihoods of 22 million people in both countries. In 2023, the oil spill at Blackhorn Port caused a 90% reduction in production for surrounding fishermen. According to the Convention on the Environment of the Congo River Basin, the oil recovery rate of oily sludge needs to be ≥ 88%. Traditional equipment is prone to clogging by impurities and has poor corrosion resistance, making it difficult to meet the demand.

China Yongle Environmental Protection Engineering has developed an "anti blocking and corrosion-resistant" oily sludge treatment equipment: using a titanium alloy anti-corrosion compartment and a fully enclosed structure, it is suitable for the saline alkali working conditions of oil fields and the high impurity environment of the Congo River. The leak prevention detection meets the standards of the International Maritime Organization; The core is equipped with a dual process of "multi-stage screening process+centrifugal separation", which first removes 99.2% of sand particles and plant residues through a three-stage vibrating screen, and then performs oil sludge separation to avoid equipment blockage, without the need for chemical agents. The oil recovery rate is over 94%, and the recovered oil can be directly supplied to oil and gas mining machinery or agricultural machinery.

Full industry chain scenario coverage: In the oil fields along the Congo River, mobile devices can be deployed with drilling platforms, with a daily processing capacity of 32 tons, to avoid sludge transportation leakage; At the Brazzaville refinery, the large centralized equipment has a daily processing capacity of 65 tons and is linked with the plant's oil supply system to achieve a "sludge oil mechanical" cycle. The treated residue has a moisture content of ≤ 14% and can be used to lay roads in the plant area; At Blackhorn Port, modular equipment processes oil tanker cleaning sludge with a daily processing capacity of 48 tons, and the recovered oil is supplied to port tugboats; At small gas stations, mini devices have a daily processing capacity of 5 tons to prevent oil sludge pollution of soil and tributaries of the Congo River.

Exclusive service guarantee: The equipment has passed the certification of the environmental departments of both countries and the technical audit of local oil companies. Set up service bases in Kinshasa and Blackhorn, reserve oil resistant and corrosion-resistant spare parts, and cooperate with local oil companies' after-sales systems to achieve 24-hour response. The equipment procurement cost is only 55% of similar international products, and the oil recovery income can cover the investment in 9 months, helping the two countries protect the ecology of the Congo River and promote the coordinated development of the oil and gas industry and fisheries.

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.
