Effect 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 degree of supersaturation, temperature, and dwell time. Variations to these parameters can drastically 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 poorer quality. Temperature, on the other hand, exerts a dual influence. While elevated temperatures often augment the growth rate, they can also reduce 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 relationship between these operating parameters is crucial for optimizing continuous crystallization processes and achieving target crystal properties.
