Title (EN) CRYSTALLIZATION METHOD AND DEVICE
(FR) PROCEDE ET DISPOSITIF DE CRISTALLISATION
Abstract: front page image
(EN)The invention concerns a crystallization method and a crystallization device therefor. The method is characterized in that it consists in circulating the crystal-loaded liquid (L), under controlled supersaturation conditions, successively in n compartments (C1, C2, ... Cn) mounted in series in a crystallization reactor (1), and in recycling the crystal slurry and recycling the mother liquor free of its fines (LMf) in each of said n compartments (C1, C2, ... Cn).
(FR)La présente invention concerne un procédé de cristallisation et un dispositif de cristallisation convenant à la mise en œuvre dudit procédé. De façon caractéristique, selon ledit procédé, le liquide (L) chargé en cristaux circule, dans des conditions de sursaturation contrôlées, dans successivement les n compartiments (Cl, C2, ... Cn) montés en série d'un réacteur de cristallisation (1) et il y a d'une part, recyclage de bouillie de cristaux et d'autre part, recyclage de liqueur mère débarrassée de ses fines (LMf) dans chacun desdits n compartiments (Cl, C2, ... , Cn).
