Proven Performance: SINOKLE Technology in Desalter Wastewater at Benchmark Refineries
Advanced technology must be validated in practice. The patented technology portfolio of SINOKLE Technology has been successfully applied at several large benchmark refining and chemical enterprises in China, achieving significant and stable treatment results.
Successful application cases:
The desalting units of Sinopec Cangzhou Petrochemical and PetroChina Sichuan Petrochemical adopted the combined process of "coalescing pressure de-oiling unit + cyclonic dissolved gas flotation".
Meanwhile, PetroChina Changqing Petrochemical and Dushanzi Petrochemical have also successfully applied its patented cyclonic dissolved gas flotation unit.
Stable, compliant treatment results:
Actual operating data show that the technology delivers outstanding results on desalter wastewater. The oil content of the effluent is stably controlled below 150 mg/L,
and the system demonstrates strong shock resistance when facing fluctuations in water quality and load, ensuring long-term stable operation.
Overview of core technical advantages:
The solution achieves outstanding results thanks to multiple advantages:
Extremely high efficiency: single-stage oil removal >90%, removing oil droplets ≥0.3 microns, with a retention time of only 1–5 minutes.
Compact footprint: volume and weight are greatly reduced, with a footprint only 1/8 to 1/3 that of conventional flotation.
Stable operation: the unique dual tangential inlet design generates stronger centrifugal force, giving superior shock resistance and adaptability to varying water quality.
Economical and convenient: simple structure, few moving parts, quick installation and low O&M costs.
Comprehensive performance: high removal of emulsified oil and fine suspended solids, usually without chemical dosing and with little scum generation.
Intelligent and reliable: fully enclosed, automated operation with pressure-driven oil and sludge discharge and no mechanical power components.
Process flow diagram:
The technology is now maturely applied to desalter oily wastewater treatment in refining and chemical enterprises, and is the preferred solution for ensuring environmental compliance and operating economy.
