Sažetak
Main focus of this work was to investigate the influence of hydrodynamic conditions on crystallization kinetics and properties of borax crystals obtained in a 15 dm 3 dual impeller batch cooling crystallizer. The two impellers used, pitched and straight blade turbine, were mounted on the same shaft. Hydrodynamics was analyzed through the values of mixing time and specific fluid flow patterns generated. Results indicate that wider metastable zones were generally observed at impeller positions characterized by higher mixing times. In those cases, growth rate constants were lower what resulted in a formation of smaller but more regularly shaped crystals. These findings imply that dual impeller position should be taken into account in order to produce crystals of desired characteristics.
