Abstract
This invention relates to a polymer membrane assembly for selective separation of permeate compositions by carbon weight. This invention also relates to a process for utilizing these polymer membrane assemblies in separation processes for selective carbon weight separation of hydrocarbon feedstreams components. More particularly, but not by way of limitation, this invention relates to the use membrane assemblies for the selective separation by carbon weight of aromatics from a hydrocarbon based feedstream.
