Impact 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 dwell time. Modifications to these parameters can profoundly affect crystal size, shape, and crystalline quality.
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 complex 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 develop.
