AI Technical Summary

Technical Problem

During the cerium purification process, the presence of the emulsion layer leads to reduced precipitation efficiency, decreased product purity, and difficulty in solid-liquid separation. Existing treatment methods cannot effectively remove solid particles and impurities, resulting in high acidity and high impurity levels in the aqueous phase, making it impossible to directly return to the production line.

Method used

The system employs a physical demulsification device and an oil-water separation device, combined with an aqueous phase impurity removal tank. Physical demulsification is achieved through a rotating shaft and a turbine propeller, while zeolite adsorption is used for impurity removal. This process separates the oil and water phases and removes impurities without the need for external reagents.

Benefits of technology

It enables continuous treatment of emulsions, and the aqueous phase can be directly returned to the sedimentation reaction tank after impurity removal, which improves sedimentation efficiency and product purity, simplifies the processing flow, and reduces processing costs.
