Abstract

Procédé de purification d'une espèce contenue dans un produit fluide par cristallisation de l'espèce au sein d'une installation le procédé comprenant au moins : - une étape (S2) de refroidissement du produit dans le réacteur par contact avec la surface d'échange thermique ; - une étape (S3) de cristallisation de l'espèce dans le réacteur ; - une étape (S4) de vidange du fluide non cristallisé hors du réacteur ; - une étape (S5) d'élimination de la rétention du fluide non cristallisé au sein de l'espèce cristallisée ; - une étape (S6) de fusion des cristaux de l'espèce dans le réacteur ; l'étape de cristallisation étant précédée par une étape de germination dans laquelle des germes se forment préférentiellement sur au moins un élément de germination distinct de la surface d'échange thermique et présentant des reliefs formant sites préférentiels de cristallisation.Process for the purification of a species contained in a fluid product by crystallization of the species within an installation, the process comprising at least: - a step (S2) of cooling the product in the reactor by contact with the surface of heat exchange; - a step (S3) of crystallization of the species in the reactor; - a step (S4) of draining the non-crystallized fluid from the reactor; - a step (S5) of eliminating the retention of the non-crystallized fluid within the crystallized species; - a step (S6) of melting the crystals of the species in the reactor; the crystallization step being preceded by a germination step in which seeds preferentially form on at least one germination element distinct from the heat exchange surface and having reliefs forming preferential crystallization sites.
