Measurement of Caustic Soda Concentration in Sodium Aluminate Solution
Based on the chemical characteristics of sodium aluminate solutions and integrating technologies such as optics and electrochemistry, we have developed a proprietary model for sodium aluminate solutions. This model enables precise measurement of alkali liquor concentrations throughout the entire Bayer process for alumina production. Tailored to the specific application requirements of different process stages—such as scale formation and slurry erosion—we have custom-designed alkali liquor line measurement systems equipped with automatic cleaning mechanisms, as well as specialized ceramic and hydrodynamic sensors for slurry monitoring.
Accurate, real-time, and continuous measurements significantly reduce reliance on laboratory sampling analyses and mitigate delays and control shortcomings associated with traditional methods. Prolisen offers comprehensive solutions leveraging these sensors to automate both leaching and evaporation processes. To date, our solutions have been installed in over 1,000 facilities across countries including Australia, China, Brazil, Indonesia, Dubai, Saudi Arabia, Vietnam, and India.
