Kazakhstan is a major producer of oil and gas in Central Asia. The oil fields along the Caspian Sea coast, the Almaty refinery, and the oil depot area produce about 250000 tons of oily sludge annually, with an oil content of 12% -95%. Some historical legacy oily soils have an oil content of 5% -10%, seriously polluting soil and groundwater. The Caspian Sea fishery resources are also facing the threat of oil pollution. According to the Marine Environmental Protection Law and the Environmental Code, oily sludge needs to be treated to an oil content of less than 2% before it can be used for agricultural cultivation. Traditional pyrolysis methods have high energy consumption and are prone to secondary pollution, and non combustible environmental treatment methods have become the mainstream demand.

China Yongle Environmental Protection Engineering has developed an integrated equipment for "environmental remediation+efficient oil extraction" based on the characteristics of oily sludge in Kazakhstan. The equipment adopts a "titanium alloy anti-corrosion cabin+fully enclosed structure" design, which is suitable for saline alkali working conditions and arid climates in oil fields. The leak proof structure has been certified by the International Maritime Organization; The core is equipped with a dual process of "hot washing+biodegradation", which does not require high-temperature combustion. The oil content of the treated sludge is less than 2%, which meets the standards for crop cultivation; At the same time, through the "gravity precipitation centrifugal separation" process, the oil recovery rate reaches over 93%, and the recovered oil can be directly supplied to oil and gas extraction machinery for use; In the preprocessing stage, the "vibrating screen impurity removal+ultrasonic demulsification" module is used to remove 99% of sand particles and impurities, avoiding equipment blockage.

Full industry chain scenario coverage: In the oil fields along the Caspian Sea coast, mobile equipment can be deployed with drilling platforms, with a daily processing capacity of 35 tons, to avoid the risk of sludge transportation leakage; In historical oil and soil remediation areas such as Mangeshtao, large-scale centralized equipment with a daily processing capacity of 100 tons is used to purify polluted soil through batch processing mode; At the Almaty Refinery, the equipment is linked with the plant's oil supply system to achieve a "sludge oil machinery" cycle, and the treated residue is used to lay roads in the plant area; At small gas stations, mini devices have a daily processing capacity of 5 tons to prevent oil sludge from contaminating the surrounding soil and groundwater.

We provide exclusive services: the equipment has passed the certification of the Ministry of Ecology of Kazakhstan and the technical standard audit of the National Petroleum Company (KazMunayGas), and meets the environmental protection requirements of the "the Belt and Road" energy cooperation. Set up service bases in Almaty and Aktau, reserve oil resistant and corrosion-resistant spare parts, and cooperate with KazMunayGas after-sales system to achieve 24-hour response. The equipment processing cost is 40% lower than traditional pyrolysis methods, and the oil recovery benefits can cover the investment within 10 months, helping Kazakhstan to repair historical oil pollution and safeguard the ecological and agricultural soil safety of the Caspian Sea.

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.
