Abstract
The present invention pertains to a process for the separation of aromatics from a feed stream, including aromatics and non-aromatics by selectively permeating the aromatics through a membrane comprising feeding a mixed phase vapor-liquid feed to a membrane wherein said liquid phase preferentially wets the surface of the membrane.
Claims12
A process for the separation of aromatics from a feedstream, including aromatics and non-aromatics and having a boiling range of at least 50° C., by selectively permeating the aromatics through a membrane comprising feeding a mixed phase vapor-liquid feed to a membrane wherein said liquid phase preferentially wets the surface of the membrane.
