Impact of Operating Parameters on Crystal Growth in Continuous Crystallizers
Crystal growth within continuous crystallizers is a intricate process influenced by numerous operating parameters. Critical Continuous Cooling Crystallizer among these are the supersaturation, temperature, and crystallization time. Modifications 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 lower purity. Temperature, on the other hand, exerts a dual influence. While elevated temperatures often increase the growth rate, they can also diminish 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 develop.
Understanding the interplay between these operating parameters is essential for optimizing continuous crystallization processes and achieving desired crystal properties.
