The Influence of Operating Parameters on Crystal Growth in Continuous Crystallizers
Crystal growth within continuous crystallizers is a intricate process influenced by numerous operating parameters. Key among these are the supersaturation, temperature, and dwell time. Adjustments to these parameters can drastically affect crystal size, shape, and crystalline quality.
For instance, higher supersaturation levels typically promote 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 stimulate the growth rate, they can also decrease crystal size and affect morphology.
Residence time plays a crucial role in determining the final crystal size by influencing the amount of time crystals have to grow.
Understanding the interplay between these operating parameters is fundamental for optimizing continuous crystallization processes and achieving target crystal properties.
