The basic mechanisms of crystallization and the principles of crystallizer operation, relating to the various crystallizer configurations in industrial use, are discussed. Crystallization is a significant separation process in the production of commodity and specialty chemicals and several different types and configurations of continuous crystallizers have been developed for these applications. Some of the factors that are needed for design, operation, and optimization of an industrial crystallizer include producing larger and more uniform crystals of the desired product, reducing the formation of agglomerates, and reducing the amount of liquid impurities included in each crystal. An industrial crystallizer must operate below the solubility curve to produce a solid phase. Its operation must be restricted to the metastable zone as the objective is to avoid the creation of a large of small particles.
