Abstract

L'invention concerne un procédé pour séparer au moins partiellement au moins deux substances d'un mélange, en particulier pour concentrer ou nettoyer, respectivement purifier, le mélange. Chacune des substances présente un point d'ébullition, respectivement d'évaporation, différent et un point de fusion, respectivement de solidification, différent. Le procédé comprend les étapes consistant à : chauffer et/ou modifier la pression du mélange, de sorte que l'état physique de l'une des substances soit différent de l'état physique d'au moins l'autre substance, le chauffage et/ou la modification de pression comprenant en outre les étapes consistant à : introduire le mélange dans un boîtier, chauffer le mélange par mise en contact d'un dispositif d'échange de chaleur disposé dans le boîtier en agitant le mélange, le mélange étant déplacé vers l'extérieur le long des surfaces d'échangeur de chaleur lors de l'agitation, et un transfert de force pour l'agitation étant effectué depuis l'extérieur du boîtier vers l'intérieur sans contact et sans passage à travers le boîtier. L'invention concerne en outre un dispositif, un concentré et une utilisation associée.
