The Czech Republic has a developed petroleum processing and machinery manufacturing industry. The Prague Refinery, Ostrava Industrial Zone, and oil depots along the Elbe River produce approximately 120000 tons of oily sludge annually, with an oil content of 25% -52%, mixed with impurities such as crude oil residue, mechanical processing oil pollution, and sand particles. If oily sludge is directly discharged, it will seriously pollute core water systems such as the Vltava River and the Elbe River - the Vltava River is the mother river of the Czech Republic, supporting the drinking water and agricultural irrigation needs of 80% of the coastal population, and is also an important shipping and ecological corridor in Central Europe. According to the EU 2000/60 Water Framework Directive and the Czech Water Resources Protection Law, the oil recovery rate of oily sludge must be ≥ 90%, and the treated residue must meet soil improvement standards. Traditional pyrolysis equipment has high energy consumption and does not meet emission standards, making environmentally friendly oil extraction equipment a necessity.

China Yongle Environmental Protection Engineering has developed the "EU Standard Environmental Protection Oil Extraction Type" oily sludge treatment equipment: using a titanium alloy anti-corrosion compartment and a fully enclosed negative pressure structure, it is suitable for salt alkali working conditions in refineries and complex impurity environments in industrial areas. The leak prevention detection meets the EU EN 12503 standard; The core is equipped with a dual process of "multi-stage screening process+low-temperature centrifugal oil extraction". First, 99.5% of sand particles and metal debris are removed through three-stage precision screening, and then the oil is separated by low-temperature centrifugation at 65 ℃, without the need for high-temperature combustion, avoiding the production of toxic gases such as dioxins. The oil recovery rate is over 94%, and the recovered oil can be refined and used as industrial fuel or mechanical lubricating oil; The oil content of the processed residue is ≤ 1.5%, which meets the EU soil improvement standards and can be used for mining area reclamation or road cushion.

Adaptation to the entire industry chain scenario: At the Prague Refinery, the large centralized equipment has a daily processing capacity of 60 tons and is linked with the plant's fuel supply system to achieve a "sludge oil industrial fuel" cycle. The processing data is uploaded in real-time to the EU environmental supervision platform; In the Ostrava Machinery Industrial Zone, the daily processing capacity of mobile equipment is 30 tons, following the on-site processing of oil and sludge by mechanical processing enterprises to avoid the risk of transportation leakage; In the oil depot area along the Yibei River, modular equipment with a daily processing capacity of 45 tons is used to clean sludge from oil tankers and recycle oil for supply to port loading and unloading machinery; At small gas stations, mini devices have a daily processing capacity of 5 tons to prevent oil sludge from polluting the surrounding soil and groundwater, ensuring the safety of drinking water.

Exclusive service guarantee: The equipment has passed the EU CE certification and dual audits by the Czech Ministry of Environment and the Water Resources Management Agency, meeting the requirements of EU cross-border environmental protection supervision. Establish service bases in Prague and Ostrava, store oil resistant and corrosion-resistant spare parts, and connect them to the local industrial maintenance network to achieve 24-hour response; Providing bilingual training for EU environmental regulations interpretation and equipment operators, the equipment procurement cost is only 55% of similar products in the EU, and the benefits of oil recovery and carbon reduction can cover the investment within 12 months, helping the Czech Republic protect the aquatic ecology and promote industrial green transformation and upgrading.

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.
