Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for extending the life of a pervaporation membrane for separating high octane components from a gasoline feed stream, including aromatics and non-aromatics and having a boiling point of at least 50° C. comprising: heating the gasoline at a temperature T f under pressure P f to partially vaporize the gasoline to produce a saturated vapor and a liquid from the gasoline; separating the vapor from the liquid; directing the vapor to a pervaporatio…
