Abstract
To investigate the growth rate of a single crystal of sodium chlorate from an aqueous solution, a flow system and an stirred cell were used in the temperature range of 16-30°C. The linear growth rate was first-order with respect to supersaturation, and the surface incorporation coefficient was found to follow the Arrhenius relationship.
The over-all growth rates of crystals in a cone type fluidized-bed crystallizer were correlated with crystal size. Using the empirical size-dependent growth rate model and the seed size distribution with a sine function, the population balance equation was integrated and the resultant population density was compared with that observed for the time after seeding. As a result, it was found that the predicted size distribution substantiated the behavior of crystals in the fluidized-bed crystallizer.
