ABSTRACT:
The present invention is directed to a crystallization process and apparatuses for such processes. In a first aspect, the process of the invention comprises a step wherein a liquid comprising a solvent and material dissolved therein, is subjected to crystallization conditions in the presence of Dean vortices, which Dean vortices result from said liquid flowing through a channel having at least one curvature. In a second aspect, the invention is directed to a crystallization process, which comprises a step wherein a liquid comprising a solvent, material dissolved therein and heterogeneous particles is subjected to crystallization conditions in the presence of Dean vortices, which Dean vortices result from said liquid flowing through a channel having at least one curvature, wherein said material crystallizes on solid surfaces, in particular on surfaces of the heterogeneous particles present in the feed.
