The petrochemical industry in South Korea is globally leading. The Ulsan Petrochemical Park, Lishui Industrial Port, and Busan Port Oil Depot generate approximately 120000 tons of oily sludge annually, with an oil content of 20% -35%, mixed with impurities such as petrochemical residues, sand and gravel, and metal debris. If these sludge are not treated properly, they can contaminate groundwater through rainwater infiltration or enter the Yellow Sea and the Korean Strait with tides, threatening fishery resources and marine ecology - South Korea's annual fishery losses caused by oil sludge pollution exceed 10 billion Korean won. According to the Marine Pollution Prevention Law, the oil recovery rate of oily sludge must not be less than 87%, and the treated residue must meet the "marine environmental protection level" standard. Traditional treatment equipment can no longer meet the strict requirements.

China Yongle Environmental Protection Engineering has developed an integrated equipment for "precise impurity removal negative pressure distillation" based on the characteristics of oily sludge in South Korea. 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 and reduce the sludge moisture content to below 19%, solving the problem 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 380-410 ℃, with an oil recovery rate of over 90%. The recovered oil meets the Korean KS M 2410 fuel standard after refining and can be directly supplied to boilers or ships in petrochemical parks. The contact parts of the equipment are made of acid and alkali resistant Hastelloy alloy, which is suitable for high corrosion conditions in the Ulsan petrochemical area and has a continuous operating life of over 32 months.

Full industry chain scenario coverage: In the Ulsan Petrochemical Park, the daily processing capacity of large-scale centralized equipment reaches 30 tons, which is linked with the park's sewage treatment system to achieve the recycling of "sludge oil separation fuel", and harmless residues are used as road cushions in the park; In the Busan Port oil depot area, mobile equipment can be deployed nearby in the oil tank area, with a daily processing capacity of 12 tons, to avoid the risk of leakage during oil sludge transportation; At Lishui Industrial Port, modular equipment processes oily sludge from chemical enterprises with a daily processing capacity of 8 tons, and the recovered oil is used for the enterprise's own power plant; In the ship maintenance area of Jeju Island, small equipment is used to process ship oil sludge, achieving "on-demand processing" and protecting the ecology of the surrounding waters of the island.

We provide localized customization services: the equipment has been certified by the South Korean Ministry of Environment and KS B 6001 Industrial Wastewater Treatment Equipment Standard, assisting customers in completing environmental protection filing and marine pollution prevention and control permits for petrochemical parks. Set up service bases in Ulsan and Busan, reserve specialized spare parts suitable for petrochemical and port scenarios, and cooperate with Hyundai Construction in South Korea to ensure equipment failure response within 24 hours. The equipment operates without secondary pollution, with wastewater and exhaust emissions exceeding South Korean environmental standards, helping to promote the green development of South Korea's petrochemical industry and safeguarding the marine ecological security of the peninsula.

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.
