Abstract

Two correlative equations were derived from population balance using Crystal Size Distribution (C. S. D) of a continuous crystallizer under steady-state operation. One related production rate, nucleation rate and crystal size; the other related production rate, growth rate, void fraction and crystal size. Product C. S. D. was expressed as cumulative amount derived from the Rosin-Rammler Method. Linear growth rate affected by crystal size was expressed as the Bransom equation. Nucleation rate and volumetric shape factor were expressed as power functions and these indexes.
A new design chart directly indicated these characteristic indexes. Industrial data reported by Aoyama were plotted on this chart and indexes were obtained from each system. These results suggest a new method of design and determination of operation conditions of industrial crystallizers.
