THE ESTIMATION OF CRYSTALLIZATION KINETICS FROM LINEAR LN N(L) VERSUS L STEADY-STATE DATA INCLUDING GROWTH-RATE DISPERSION

A discussion of modelling of nucleation and crystal growth kinetics is presented for those mixed-suspension, mixed product removal (MSMPR) crystallizer data available in the literature, for which log population density data appears to be a linear function of crystal size. The modelling crystallization kinetics is done twice - once assuming that the system is obeying McCabe's DELTAL law, and again when the crystals exhibit growth rate dispersion (GRD). In the latter case the gamma, inverse gamma, log-normal, beta, Fisher, sum of two gammas, sum of two inverse gammas, sum of two log-normal, and sum of two constant rates of growth rate dispersion models are used for crystal growth rate estimation. Finally, McCabe's and GRD predictions are compared with the size-dependent growth rate estimations.
