Crystallization kinetics of Sodium Sulfate Decahydrate in an MSMPR stirred crystallizer

Experimental work on a sodium sulfate-water system was carried out using two liter crystallizers by cooling. Different impeller velocities and suspension densities were used. Experimental evidence from continuous crystallizers frequently shows, at least for small crystals, deviation from the McCabe Delta L law. The relation between growth rate and particle size is investigated. The methods of estimation of kinetics for industrial use are discussed. The experimental data of population density distribution was fitted directly by the three-parameter model presented by Mydlarz and Jones for a steady state MSMPR crystallizer. The relationship between the parameters of kinetics of both nucleation and growth rate and supersaturation was obtained by analyzing experimental data.
