Effect 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 residence time. Variations to these parameters can profoundly affect crystal size, shape, and morphology.
For instance, higher supersaturation levels typically accelerate crystal growth rate but may also lead to smaller crystals with lower purity. Temperature, on the other hand, exerts a complex influence. While elevated temperatures often increase the growth rate, they can also reduce crystal size and modify morphology.
Residence time plays a crucial role in determining the ultimate crystal size by influencing the amount of time crystals have to develop.
Understanding the correlation between these operating parameters is fundamental for optimizing continuous crystallization processes and achieving desired crystal properties.
