(EN) ULTRAFILTRATION PROCESS FOR PRODUCING A SULFOPOLYESTER CONCENTRATE
(FR) PROCÉDÉ D'ULTRAFILTRATION POUR PRODUIRE UN CONCENTRAT DE SULFOPOLYESTER
Abrégé
(EN)
A process for recovering a primary polymer concentrate stream is provided. The process comprises routing a second mother liquor stream to a primary concentration zone to remove water from the second mother liquor stream to produce the primary polymer concentrate stream; wherein the primary concentration zone comprises at least one ultrafiltration membrane. A process is also provided to recover sulfopolyester from the primary polymer concentrate stream and to produce articles therefrom.
(FR)
L'invention concerne un procédé de récupération d'un courant de concentrat de polymère primaire. Le procédé comprend l'orientation d'un second courant de liqueur mère vers une zone de concentration primaire pour retirer l'eau du second courant de liqueur mère afin de produire le courant de concentrat de polymère primaire, la zone de concentration primaire comprenant au moins une membrane d'ultrafiltration. L'invention concerne également un procédé de récupération de sulfopolyester à partie du courant de concentrat de polymère primaire et de production d'articles à partir de celui-ci.
