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, heat transfer rate, and dwell 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 quality. Temperature, on the other hand, exerts a dual influence. While elevated temperatures often increase the growth rate, they can also diminish 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 develop.
Understanding the relationship between these operating parameters is crucial for optimizing continuous crystallization processes and achieving desired crystal properties.
