Study on the Crystallization Kinetics of Sodium Chloride in a Stirred Type Crystallizer

Abstract Sodium chloride, known for its stability, is widely used in various industries including industrial manufacturing, food processing, and pharmaceuticals. To better understand the crystallization mechanism of sodium chloride and optimize its crystallization process, this study simulates the crystallization kinetics of sodium chloride in a stirred bed crystallizer. The nucleation and growth processes of sodium chloride crystals at 30°C during the stirring crystallization process were investigated. The effects of stirring rate, supersaturation, and suspension density on the crystallization process were analyzed. A kinetic model for the nucleation and growth of sodium chloride crystals was constructed using multivariate nonlinear fitting based on the collected data.
