Impurities Incrustation

Moreover, scale up of the data obtained is virtually impossible, mainly due to different hydrodynamic conditions in the pi-lot-scale plant and the technical plant, impurities in the technical crystallizer which influence nucleation and crystal growth, and different heat transfer coefficients caused by different degrees of incrustation (or fouling) in pilot-scale and technical plants. Different models plug flow, macromixing, etc.) are discussed in [7.38] which consider deviations from ideal behavior in an MSMPR crystallizer. Results of scale up for this type of crystallizer are given in [7.48].
