IMPROVED MEMBRANE SEPARATION PROCESS USING MIXED VAPOR-LIQUID FEED

The present invention pertains to a pervaporation membrane process for the separation of high octane fuel components from a gasoline feed stream comprising feeding a mixed phase vapor-liquid feed to a cyclone separation means to separate the liquid from the vapor, then sending the saturated vapor to...

Beschreibung
Zusammenfassung:	The present invention pertains to a pervaporation membrane process for the separation of high octane fuel components from a gasoline feed stream comprising feeding a mixed phase vapor-liquid feed to a cyclone separation means to separate the liquid from the vapor, then sending the saturated vapor to the membrane, thereby extending the useful life of the membrane. La présente invention concerne un procédé à membrane de pervaporation pour la séparation de composants de carburant à indice d'octane élevé à partir d'un courant d'alimentation d'essence comprenant l'introduction d'une alimentation vapeur-liquide à phases mixtes dans un moyen de séparation par cyclone pour séparer le liquide de la vapeur, puis l'envoi de la vapeur saturée vers la membrane, permettant ainsi de prolonger la durée de vie utile de la membrane.
