[ What is claimed is:] [1.] A process for removing carbon dioxide from a fluorocarbon carbon dioxide mixture comprising one or more stages in which a feed stream of said fluorocarbon carbon dioxide mixture is contacted with a semipermeable membrane to form at least one exit stream having an increased concentration of carbon dioxide and at least one exit stream having a reduced concentration of carbon dioxide, said process in at least one of said one or more stages causing said exit stream with increased concentration of carbon dioxide to contain less than about 5% by weight of the fluorocarbon present in said feed stream.
