Effect 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 crystallization 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 poorer quality. Temperature, on the other hand, exerts a complex influence. While elevated temperatures often augment the growth rate, they can also reduce crystal size and alter 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 relationship between these operating parameters is essential for optimizing continuous crystallization processes and achieving target crystal properties.
