Disclosed is a process for devolatilizing a polymer comprising the polymer through a devolatizer comprising a plate heat exchanger wherein the plate heat exchanger are heated by a plurality of heating tubes and wherein the heating tube comprises a return tube nested inside of a supply tube. The use of the disclosed invention allows for a comparatively small heat profile across heating plates as compared to prior art plate heat exchangers.
Procédé de dévolatilisation d'un polymère qui consiste à faire passer ce polymère par un dévolatiliseur comportant un échangeur de chaleur à plaques, les plaques de l'échangeur de chaleur étant chauffées par une pluralité de tubes de chauffe et chaque tube de chauffe comprenant un tube de retour logé à l'intérieur d'un tube d'alimentation. L'utilisation du procédé selon la présente invention permet un profil de chaleur comparativement faible sur les plaques de chauffe par rapport aux échangeurs de chaleur selon l'art antérieur.
