Impact of Operating Parameters on Crystal Growth in Continuous Crystallizers
Crystal growth within continuous crystallizers is a intricate process influenced by numerous operating parameters. Essential among these are the supersaturation, heat transfer rate, and residence time. Modifications to these parameters can profoundly affect crystal size, shape, and morphology.
For instance, higher supersaturation levels typically enhance crystal growth rate but may also lead to smaller crystals with lower 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 final crystal size by influencing the amount of time crystals have to mature.
Understanding the correlation between these operating parameters is essential for optimizing continuous crystallization processes and achieving specific crystal properties.
