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, thermal conditions, and dwell time. Variations to these parameters can significantly affect crystal size, shape, and crystalline quality.
For instance, higher supersaturation levels typically accelerate crystal growth rate but may also lead to smaller crystals with reduced purity. Temperature, on the other hand, exerts a faceted influence. While elevated temperatures often augment 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 grow.
Understanding the interplay between these operating parameters is essential for optimizing continuous crystallization processes and achieving target crystal properties.
