    摘要: A mixture of air and one or more halogenated alkanes is directed to a gas separation membrane where it is separated into an oxygen, nitrogen, and moisture-enriched and halogenated alkane-depleted permeate and a halogenated alkane-enriched and oxygen, nitrogen, and moisture-depleted retentate. The retentate is directed to a cryogenic condenser where an amount of halogenated alkane is condensed therein.
