Oil and gas exploitation (Texas, Alaska), oil refining and processing, machinery manufacturing, port and wharf, airport ground handling and other industries in the United States are developed, and a large amount of oily sludge is produced every year, with an oil content of 25% - 58%. The mixture of crude oil residues, sand particles, oil pollution and other impurities belongs to the hazardous waste strictly controlled by EPA. EPA clearly requires that the oil content of residue after oily sludge treatment shall be ≤ 0.3%, the waste water shall be recycled or discharged according to the standard, and the leakage of oil pollution is strictly prohibited to pollute the soil, groundwater and watercourse, and enterprises will face huge fines, production bans and even criminal liabilities in case of illegal disposal. At present, the oily sludge treatment in America is faced with many difficulties: the traditional hot washing and centrifugal process are not thorough in oil removal, the oil content of residue exceeds the standard, and the landfill cannot be carried out in compliance with the regulations; High reagent consumption, secondary hazardous waste and high disposal cost; Oil and gas fields and refineries are mostly distributed in remote areas. The equipment shall have strong mobility and be resistant to complex working conditions. Meanwhile, it shall be equipped with English monitoring system to meet EPA verification requirements.

The customized American oily sludge treatment equipment strictly follows the EPA hazardous waste disposal standard and is specially designed for the characteristics of American industrial oily sludge. With high efficiency oil removal, compliance and environmental protection, it can completely solve the problem of oily sludge pollution. The equipment adopts the triple process of "multi-stage screening+low-temperature oxygen-free pyrolysis+oil-water separation". First, remove the sand and metal chips in the sludge through the intelligent screening system to reduce the difficulty of pyrolysis; Then, the oil is separated by 488 ℃ low-temperature oxygen-free pyrolysis technology, the oil recovery rate reaches 95.5%, and the recovered oil has high purity, which can be directly returned to the refinery for refining or used as industrial fuel to realize resource recovery; The oil content of the residue after treatment is ≤ 0.22%, non-toxic and harmless, which can be safely landfilled or used for soil improvement and meets the disposal standard of EPA; Waste water, after advanced purification treatment, meets the EPA discharge standard and can be recycled or discharged in compliance, without secondary pollution in the whole process.

The whole site is suitable for industrial demands: in the oil and gas field operation areas in Texas and Alaska, the mobile equipment is flexibly deployed with the drilling platform, with a daily processing capacity of 45t. It is specially used for the disposal of oil-based drilling mud and drilling rock debris. The anti-seepage design avoids the pollution of soil and groundwater by oil pollution, and it is suitable for remote areas and complex road conditions; In California and Texas Refineries, the daily processing capacity of large centralized equipment is 88t, which is seamlessly linked with the oil supply system of the plant area to form a "sludge - oil product - energy" closed loop, greatly improving the resource utilization rate and reducing the production cost; The daily processing capacity of modular equipment is 70t at the port, wharf and ship maintenance plant, and the oily sludge generated from tanker cleaning and ship maintenance is treated on site. The anti-seepage design protects the marine and coastal ecology; In the machinery manufacturing and airport ground service industry, the daily processing capacity of small equipment is 8 tons, which is low cost and easy to operate. It adapts to the disposal demand of small enterprises. The oil recovery revenue can quickly cover the equipment input.

Compliance and localization guarantee: the equipment has passed all EPA compliance reviews, which can assist enterprises in filing hazardous waste disposal qualification and handling pollution discharge permit, and provide complete EPA compliance certification documents for the convenience of verification by environmental protection departments; Equipped with English intelligent monitoring system, it can monitor the disposal parameters and emission indicators in real time, and the data can be uploaded to the EPA supervision platform in real time, so as to achieve the whole-process traceability; Anti-corrosion and anti-stick cabin design is adopted to withstand the corrosion of oily sludge, avoid wall blocking, extend the service life of equipment, and adapt to complex industrial working conditions in the United States; Standardized service bases are set up in Texas, California and New York, core spare parts are stored, 24-hour maintenance response is realized, and door-to-door maintenance service is provided in remote areas; The operation interface is in English, which simplifies the operation and maintenance process, adapts to the operation habits of American industrial operation and maintenance personnel, assists enterprises to achieve compliance disposal of oily sludge, reduces environmental risks, and achieves win-win economic and environmental benefits.
