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 degree of supersaturation, temperature, and dwell time. Adjustments to these parameters can drastically affect crystal size, shape, and morphology.
For instance, higher supersaturation levels typically promote crystal growth rate but may also lead to smaller crystals with reduced 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 affect morphology.
Residence time plays a crucial role in determining the equilibrium crystal size by influencing the amount of time crystals have to grow.
Understanding the interplay between these operating parameters is essential for Continuous Crystallizer optimizing continuous crystallization processes and achieving target crystal properties.
