Title
(EN) A PROCESS FOR THE RECOVERY OF A FERMENTATION PRODUCT
(FR) PROCÉDÉ DE RÉCUPÉRATION D'UN PRODUIT DE FERMENTATION
Abstract
(EN)
The present invention provides a process for the purification and oncentration of a partially water-soluble organic product from a source containing the same at concentration C0, which process comprises the steps of: (i) concentrating said product by means of a resin to form a first aqueous solution at concentration of C1; and (ii) fractionating an aqueous solution by temperature adjustment to form a second aqueous solution and a third aqueous solution with concentrations C2 and C3, respectively, wherein C2>C3 and C2>C1>C0.
(FR)
La présente invention concerne un procédé pour la purification et la concentration d'un produit organique partiellement soluble dans l'eau à partir d'une source contenant celui-ci à une concentration C0. Ce procédé comprend les étapes consistant à (i) concentrer ledit produit au moyen d'une résine pour former une première solution aqueuse à une concentration C1, et à (ii) fractionner une solution aqueuse par ajustement de la température pour former une seconde solution aqueuse et une troisième solution aqueuse à des concentrations respectives C2 et C3, avec C2>C3 et C2>C1>C0.
