Ozone Catalysis + Cyclonic Separation + Flotation Deoiling: CDOF's Triple Technology Solves Ternary Precursor Treatment Challenges
Ternary precursor product liquid is a key material in the new energy field; the high concentrations of oil and total organic carbon (TOC) it contains pose major challenges to downstream product performance and subsequent treatment.
Limitations of conventional processes
As conventional treatment methods, activated carbon and resin adsorption have significant defects:
High cost: coconut-shell activated carbon and special resins are required, and raw material costs are high
Hazardous waste problem: saturated activated carbon becomes hazardous waste, and outsourced disposal increases operating costs
Cumbersome operation: activated carbon must be replaced every two days, relying on manual attendance
Safety risk: ethanol is used for resin regeneration, posing safety hazards.
CDOFInnovative Process
SINOKLE Technology has developed an integrated ozone flotation device (CDOF) that, by integrating the three core technologies of ozone catalytic oxidation, hydraulic cyclonic separation and flotation deoiling, together with a self-developed acid-resistant modified heterogeneous ozone catalyst, achieves efficient oil removal and TOC reduction while ensuring that the ionic composition and purity of the product liquid are not affected.
