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 among these are the supersaturation, thermal conditions, and crystallization time. Variations to these parameters can profoundly affect crystal size, shape, and purity.
For instance, higher supersaturation levels typically accelerate 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 Continuous Crystallizer 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 grow.
