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 crystallization time. Modifications to these parameters can drastically affect crystal size, shape, and morphology.
For instance, higher supersaturation levels typically accelerate crystal growth rate but may also lead to smaller crystals with poorer purity. Temperature, on the other hand, exerts a faceted influence. While elevated temperatures often stimulate 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 more info grow.
Understanding the interplay between these operating parameters is fundamental for optimizing continuous crystallization processes and achieving target crystal properties.
