The petroleum, chemical, and automotive manufacturing industries in the United States are well-developed, with oil fields in the Gulf of Mexico, refining belts in Texas, and industrial clusters in the Great Lakes region producing approximately 1.2 million tons of oily sludge annually, with an oil content generally ranging from 15% to 30%, mixed with impurities such as sand and gravel, metal debris, and chemical additives. If these sludge are not treated properly, they can contaminate groundwater through rainwater infiltration or enter the Gulf of Mexico and Mississippi River through surface runoff, posing a threat to aquatic ecology and fishery resources. According to the Clean Water Act (CWA) and the Oil Pollution Act (OPA) in the United States, the oil recovery rate of oily sludge must not be less than 85%, and the treated residue must meet the standard of "no harmful components". Traditional landfill and incineration methods have been strictly restricted, and efficient and environmentally friendly treatment equipment has become a must-have for energy and industrial enterprises.

Based on the characteristics of oily sludge in the United States, China Yongle Environmental Protection Engineering has developed an integrated equipment of "precision pretreatment low temperature distillation deep purification": in the pretreatment stage, a triple module of "cyclone sand removal+magnetic separation iron removal+centrifugal dehydration" is used to remove more than 98% of solid impurities, reduce the sludge moisture content to below 20%, and solve the pain point of traditional equipment blockage; The core distillation system adopts the technology of "intelligent temperature control+negative pressure distillation" to achieve efficient oil separation in a low-temperature environment of 390-420 ℃, with an oil recovery rate of over 89%. The recovered oil can meet the American API standards after refining and can be directly reused in industrial production or sold as fuel. The contact components of the equipment are made of Hastelloy alloy material, optimized for high sulfur and high corrosion sludge, with a continuous operating life of over 30 months, suitable for harsh working conditions such as high salt spray in the Gulf of Mexico and high temperatures in Texas.

Full industry chain scenario coverage: In offshore oil fields in the Gulf of Mexico, mobile equipment can be carried on drilling platforms or transport ships, with a daily processing capacity of 10 tons, avoiding the risk of marine leakage caused by long-distance transportation of oily sludge. The separated oil is directly transported back to the production system; At the Houston Refinery in Texas, the daily processing capacity of large-scale centralized equipment reaches 30 tons, which is linked with the plant's sewage treatment system to achieve the recycling of "sludge oil separation fuel". The harmless residue can be used to produce environmentally friendly building materials; At the Michigan automobile manufacturing plant, modular equipment is specialized in processing oily sludge generated during mechanical maintenance, with a daily processing capacity of 5 tons. The recovered oil is used for lubrication of workshop equipment, reducing production costs.

We provide localization services in the United States: our equipment has passed EPA certification and API petroleum equipment certification, assisting customers in completing compliance filing with federal and state environmental departments, and providing one-stop services from equipment installation and commissioning to operator training. Set up two service bases in Houston and New Orleans, reserve specialized spare parts suitable for oil fields, refineries, and other scenarios, and cooperate with local engineering service companies to ensure equipment failure response within 24 hours. The equipment operates without secondary pollution, with wastewater and exhaust emissions exceeding US environmental standards. It can be safely deployed in sensitive areas such as oil fields, refineries, and ports, helping customers achieve the dual goals of ecological protection and 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.
