Estimation of crystallization kinetics from batch cooling experiments

Simultaneous prediction of crystal shape and size for solution crystallization

“…The saturation concentration and metastable zone width for succinic acid grown from water at this temperature are 104.29 g/kg water, and about 5 g/kg water, respectively (Qiu and Rasmuson, 1994). The face growth and secondary nucleation kinetics are assumed to follow empirical power law models The empirical growth model for the (020) face is obtained from Mullin and Whiting (1980), the secondary nucleation rate model is obtained from Qiu and Rasmuson (1994). The model parameters are listed in Table 3 for reference.…”

Mechanisms of initiation of incrustation

“…This is a quite weak dependence for a phenomenon assumed to be related to secondary nucleation. Qiu and Rasmuson (1994) found the rate of secondary nucleation for succinic acid crystallized in aqueous solutions to depend on supersaturation to the order of 2.4, and in general the exponent ranges from 2 to 4 for different substances (Garside and Davey, 1980). According to the "survival theory" (Garabedian and Strickland-Constable, 1972a,b), a size distribution of pre-nuclei embryos are generated at the mechanical contact.…”

Operating Strategy for Continuous Multistage Mixed Suspension and Mixed Product Removal (MSMPR) Crystallization Processes Depending on Crystallization Kinetic Parameters

“…The ranges of variation for the growth and nucleation rate orders were selected to incorporate the experimentally estimated kinetic parameters from the literature. 11,33,[42][43][44][45][46][47][48][49] By varying the orders, the CSD in the product effluent stream can be determined when each order is higher or lower than 1. The range of variation of the stage number was one to ten, even though the stage number would generally not be more than six.…”
