Abstract:
Process for separating a highly pure propylene product from a liquefied petroleum gas stream is disclosed, which eliminates a C3 splitter having over 120 trays and the additional equipment that a C3 splitter requires. The process includes passing a feed stream to a dividing wall column to produce an overhead stream, a first side draw stream, a second side draw stream, and a product stream. The first side draw stream is passed to a treatment unit to produce a treated stream. The treated stream is passed to a membrane unit and a permeate stream is passed from the membrane unit to produce a polymer grade propylene stream.

Claim (Index 11):
The process of  claim 8 , wherein the membrane unit comprises a plurality of membranes wherein said membranes are facilitated transport membranes comprising a nanoporous support membrane, a hydrophilic polymer inside the nanopores on a skin layer surface of the nanoporous support membrane, a thin, nonporous, hydrophilic polymer layer coated on the surface of the nanoporous support membrane, and metal salts incorporated in the hydrophilic polymer layer coated on the surface of the nanoporous support membrane and the hydrophilic polymer inside the nanopores.
