Title (EN) ROTARY VACUUM FILTER, METHOD, AND USE
(FR) FILTRE À VIDE ROTATIF, PROCÉDÉ ET UTILISATION
Abstract:
(EN) A rotary vacuum filter for separation of bisphenol A-phenol adduct crystals from a crystallization liquor is provided. The rotary vacuum filter includes a filter drum with a perforated sector on a lateral surface of the filter drum; a non-polymeric filter cloth attached to the filter drum and covering said perforated sector; and a vacuum pump in fluid communication with an interior surface of the perforated sector. Methods and uses of thereof are also provided.
(FR) L'invention concerne un filtre à vide rotatif pour la séparation de cristaux de produit d'addition de bisphénol A-phénol à partir d'une liqueur de cristallisation. Le filtre à vide rotatif comprend un tambour de filtre ayant un secteur perforé sur une surface latérale du tambour de filtre; un tissu de filtre non polymère fixé au tambour de filtre et recouvrant ledit secteur perforé; et une pompe à vide en communication fluidique avec une surface intérieure du secteur perforé. L'invention concerne également des procédés et des utilisations associés.
