Sodium aluminate solution RP/αK measurement

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 real-time measurement of RP/αK concentrations throughout the entire Bayer process for alumina production. Tailored ceramic and hydrodynamic designs of slurry sensors have been specially developed to meet the application-specific requirements of different process stages, including scale formation and slurry erosion. Accurate, real-time, and continuous measurements significantly reduce reliance on laboratory sampling and analysis, as well as the drawbacks associated with delayed control. Prolisen offers solutions that leverage these sensors to automate both leaching and evaporation processes. To date, over 500 installations have been carried out in countries including Australia, China, Brazil, Indonesia, Dubai, Saudi Arabia, Vietnam, and India.
