Abstract

New data are presented on the crystallization of potash alum (KAl(SO₄)₂·12H₂O) from solution, in a continuously operating MSMPR cooling crystallizer, 61 in volume. Population density distributions were determined by sieve analysis. Highly polydispersed product was obtained, with median crystal size, L₅₀, in the range between 264 and 607 μm. Suspension density was varied between m_T = 7 and 98 kg/m³. The results were evaluated according to an attrition model and the obtained kinetic efficiency should be valid for other types of crystallizers.
