Title (EN) PROCESS FOR MAKING A SOLID COMPOUND BY PRECIPITATION, SUSPENSIONS OF SOLID IN LIQUIDS AND SOLIDS OBTAINED BY THE PROCESS AND THEIR USE AS ADDITIVES
(FR) PROCEDE DE PRODUCTION D'UN COMPOSE SOLIDE PAR PRECIPITATION SUSPENSIONS DE SOLIDES DANS DES LIQUIDES, ET SOLIDES OBTENUS AU MOYEN DUDIT PROCEDE ET LEUR UTILISATION COMME ADDITIFS
Abstract:
(EN) Process for making a solid compound by precipitation, using a high intensity mixing reactor and comprising the steps of (A) introducing a first fluid material containing a first reactant and a second fluid material containing a second reactant into said reactor, in order to obtain a mixed fluid, in order to cause the first reactant to react with the second reactant to form a solid compound by precipitation in the mixed fluid; (B) withdrawing the mixed fluid containing the precipitated solid obtained in step (A) from the reactor, and; (C) optionally separat ing the precipitated solid compound from at least one fraction of the mixed fluid.
(FR) L'invention porte sur un procédé de production d'un composé solide par précipitation utilisant un réacteur à forte intensité de mélange, et comportant les étapes suivantes: (A) introduction dans le réacteur d'un premier matériau fluide contenant un premier réactif et d'un deuxième matériau fluide contenant un deuxième réactif afin d'obtenir un mélange fluide et d'amener le premier réactif à réagir avec le deuxième pour former un composé solide par précipitation dans le mélange fluide, (B) extraction du réacteur du mélange fluide contenant le précipité solide de l'étape (A), et (C) séparation facultative du composé solide précipité, d'avec au moins une fraction du mélange fluide.
