Nucleation and Crystal Growth in MSMPR Crystallizers

Dealing with industrial ciystallization it is necessary to limit the supersaturation and the kinetic parameter nucleation and growth to produce crystals with sizes and purities wanted by the customer. The metastable zone valid for primary homogeneous nucleation has already been discussed, see Fig. 8.4-5. Industrial crystallizers are operated at supersaturations which are one order of magnitude lower than ACmet, hom (Ac 0.1 Ac j om ) This means that substances with a high solubility 

A general predictive calculation of nucleation rates is difBcult with respect to the complex processes involved as attrition and the presence of foreign particles and 

The results obtained for potash alum show that the effective nucleation rate increases with rising mean specific power inputs for given growth rates. This can
