Scale-up problems in crystallizers with the draft tube and propeller
MAŁYSIAK A., SYnoWIEC P.M., WÓJCIK J.
Please cite as: CHEMIK 2014, 68, 202–204
The paper deals with scale-up problems. The issue is discussed in the light of draft tube magma crystallizer, commonly used in crystallization processes from solution. Authors defined the parameters mainly affecting the crystallization and product requirements during scale-up on one hand and on another consider, what can be done when...
The Metastable Zone of aqueous solutions
BoGACZ W., WÓJCIK J.
Please cite as: CHEMIK 2014, 68, 198–201
The Metastable Zone (MSZ) is one of the most essential notions in industrial crystallization. However, its definitions have still some vagueness, and models to estimate the metastable limit (MSL) have not been matured enough to be used in practical operation. This paper presents the results of studies of determination the nucleation point and the MSZW of...
