Effect of Operating Parameters on Crystal Growth in Continuous Crystallizers
Crystal growth within continuous crystallizers is a intricate process influenced by numerous operating parameters. Critical among these are the concentration, thermal conditions, and residence time. Variations to these parameters can profoundly affect crystal size, shape, and purity.
For instance, higher supersaturation levels typically promote crystal growth rate but may also lead to smaller crystals with reduced purity. Temperature, on the other hand, exerts a dual influence. While elevated temperatures often stimulate the growth rate, they can also decrease crystal size and modify morphology.
Residence time plays a crucial role in determining the equilibrium crystal size by influencing the amount of time crystals have to mature.
