Beschreibung
Zusammenfassung:	A device and process for crystallizing a compound using hydrodynamic cavitation comprising the steps of mixing at least one stream of a solution of such compound to be crystallized with at least one stream of an anti-solvent and passing the mixed streams at an elevated pressure through a local constriction of flow to create hydrodynamic cavitation thereby causing nucleation and the direct production of crystals. L'invention concerne un dispositif et un procédé de cristallisation d'un composé au moyen d'une cavitation hydrodynamique. Ledit procédé consiste à mélanger au moins un flux d'une solution contenant ce composé à cristalliser, avec au moins un flux d'un anti-solvant, et à passer les flux mélangés à une pression élevée à travers une constriction locale de flux, afin de créer une cavitation hydrodynamique, ce qui permet de provoquer une nucléation et la production directe de cristaux.
