Abstract

A process for separating at least one polyolefin from a product stream derived from a polyolefin recycling process, wherein the product stream comprises at least one polyolefin and a solvent, and the process comprises the steps of: separating the product stream into a polyolefin-lean stream and a polyolefin-rich stream; separating the polyolefin-rich stream into a first polyolefin-lean vapor stream and a first condensed polyolefin-rich stream; and separating the first condensed polyolefin-rich stream into a final polyolefin-lean vapor stream and a final condensed polyolefin-rich stream.
