Impeller geometry effect on crystallization kinetics of borax decahydrate in a batch cooling crystallizer

Connection of Hydrodynamics and Nucleation Kinetics in Dual‐Impeller Crystallizers

“…8, it can be concluded that shear stress was lower in the 2 PBT than in the 2 SBT dual‐impeller system. A similar trend was found in previous research 1, 9. Thus, it can be assumed that agglomeration is favored under low shear stress conditions.…”

“…To ensure optimum conditions for mass and energy transfer 5, 6 in batch crystallizers, mixing needs to be applied. Most of the previous researches have been conducted in single‐impeller systems 7–9 but available data is scarce for crystallizations in multiple‐impeller systems. In that case, hydrodynamic conditions in the vessel become more complex 10–12.…”

Total Synthesis of (–)‐Isoamericanin A and (+)‐Isoamericanol A

“…Thus, the apparent nucleation order does not vary much with varying agitation while the nucleation rate constant increases with increasing agitation rate. Such a dependence of the kinetic parameters of nucleation ( n and k n ) on the agitation rate is well documented in the literature for other crystallizing solutes 24, 26. Bonnin‐Paris et al 27 reported an average value of the apparent nucleation order of 3.5 ± 0.5 for cooling batch crystallization of glycine.…”

Design of co-crystallization processes with regard to particle size distribution

“…There are several essential process parameters that have an influence on the final CSD e.g. supersaturation, seeding policy including quantity of seeds and their size and finally crystallizer characteristics such as impeller geometry, stirring rate (Akrap et al, 2012), etc. Cooling crystallization exploits the fact that solubility of most compounds depends on temperature.…”
