Effects of Properties of Crystalline Particles on Mother Liquor Holdup in Crystal Cake and Residue Behaviors of Impurities

In industrial crystallization, all impurity species need to be removed, regardless of the kind present in raw materials. Removing mother liquor is required because a crystal cake with holdup frequently formed by crystalline particles during solid-liquid separation suspension-type melt crystallization. This study aims make clear relationship between and characteristics cake, difference residue behaviors impurities based on new concept for understanding holdup. As result, initial depended specific surface area cake. Investigating behavior each suggests that impurity-based inclusion factors were different from solvent-based factor depending impurity. Furthermore, certain had dependence residual amount
