Title (EN) PROCESS AND ROTARY PRESSURE FILTRATION APPARATUS FOR SLURRY SEPARATION OF AROMATIC CARBOXYLIC ACIDS
(FR) PROCÉDÉ ET APPAREIL ROTATIF DE FILTRATION SOUS PRESSION PERMETTANT DE SÉPARER LES ACIDES CARBOXYLIQUES AROMATIQUES D'UNE SUSPENSION ÉPAISSE
Abstract: front page image
(EN)A process for removing aromatic carboxylic acid from a slurry thereof in solvent comprising the steps of: (a) splitting the slurry into sub streams and supplying each of said sub streams to a respective rotary pressure filters such that said sub stream pass through the filters in parallel; and (b) passing gas through the rotary pressure filters in series in an open-loop arrangement.
(FR)L'invention porte sur un procédé qui permet d'enlever les acides carboxyliques aromatiques de la suspension épaisse qu'ils forment dans un solvant, lequel procédé consiste (a) à diviser la suspension en des flux secondaires et diriger chacun desdits flux secondaires vers un filtre à pression rotatif respectif de manière que les flux secondaires passent à travers les filtres en parallèle, et (b) à faire passer un gaz à travers les filtres à pression rotatifs en série selon un agencement en boucle ouverte.
