Abstract

L'invention concerne un procédé de production d'un produit d'acide carboxylique purifié. Ce procédé consiste à décharger les impuretés d'une boue d'acide carboxylique brute dans une zone de déplacement solide-liquide afin de former une boue. Cette boue est ensuite traitée dans une zone d'oxydation étagée et une zone de cristallisation afin de former un produit cristallisé. Ce produit cristallisé est ensuite refroidi dans une zone de refroidissement, puis filtré et séché dans une zone de filtrage et de séchage. Le procédé produit un acide carboxylique purifié de couleur agréable et à niveaux d'impuretés faibles sans utiliser d'étape de purification telle que l'hydrogénation.
