In the oil extraction and storage industry, the disposal of oily sludge has long been a thorny environmental challenge. The 1m³/h oily sludge treatment system launched by KOSUN is a compact, high-efficiency solution specifically designed for the harmless and resource-oriented treatment of various types of oily sludge. Capable of handling floor oily sludge, drill cuttings, and tank cleaning residues, this system utilizes a sophisticated closed-loop process to transform “black waste” into valuable resources, making it an ideal choice for petroleum and petrochemical enterprises to achieve both environmental compliance and economic growth.
Core Technology: Chemical Hot Washing and Multi-stage Fine Separation
At the heart of the system is advanced chemical hot washing technology. By adding a specialized formula of surfactants and maintaining optimal temperatures, the stable “oil-water-solid” emulsion structure is thoroughly broken, allowing crude oil to be stripped from the surface of solid particles. Subsequently, the mixture enters high-speed decanter centrifuges or disc centrifuge units, where powerful centrifugal force achieves precise separation of the oil, water, and solid phases. This process ensures continuous operation and maximizes the recovery of crude oil from complex sludge mixtures.
Key Advantages: Resource Recovery and High Return on Investment
This system offers a significant cost advantage and an attractive investment recovery period for enterprises. Compared to traditional high-temperature incineration or pyrolysis, the 1m³ system provides better control over energy consumption and chemical costs. The recovered crude oil is of high purity and can be sold directly to refineries as raw material, effectively turning waste into treasure. Furthermore, the purified water, with oil content as low as 200mg/L, can be fully reused in the system’s own hot washing process. This closed-loop cycle significantly reduces fresh water consumption and wastewater discharge fees.
Treatment Results: Solid Phase Compliance and Harmless Disposal
Through its comprehensive process, the system demonstrates excellent capacity for waste reduction and resource recovery. After treatment, the oil content in the solid residue is stably reduced to below 2%, far exceeding national standards for general hazardous waste landfilling. This creates favorable conditions for subsequent deep disposal methods such as pyrolysis, incineration, or biodegradation. Whether dealing with floor sludge from oilfield operations or sediment from storage tanks, the system achieves high-efficiency purification, helping companies meet stringent environmental policies while reaching their green and sustainable production goals.
