Growth rate dispersion vs size-dependent growth rate for MSMPR crystallizer data

Abstract

A discussion of modeling of crystal growth kinetics for real MSMPR crystallizer data is presented. The modeling of growth kinetics is done twice—once assuming that growth rate dispersion is a source of curvature in the log population density vs size data plot and again when this curvature is caused by size-dependent growth. Calculations clearly indicate that, when experimental log population density vs size data plots exhibit curvature, use of the size-dependent growth rate approach gives more reliable growth kinetics across a broad crystal size range than those obtained from modeling of growth kinetics by growth rate dispersion.
