Beschreibung
Zusammenfassung:The invention provides a process for recovering a gaseous component comprising at least one fluorine-containing compound from a mixture of gaseous compounds. The process includes, in a separation zone (12), bringing a mixture of gaseous constituents, including at least one fluorine-containing constituent, into contact with a gas permeable separating medium (16) comprising a polymeric compound, so that a first gaseous component comprising at least one fluorine-containing constituent is separated from a second gaseous component comprising the balance of the gaseous constituents. The first gaseous component is withdrawn from the separation zone as a permeate (34) or a retentate, while the second gaseous component is withdrawn from the separation zone as the retentate (26), when the first gaseous component is withdrawn as the permeate, and as the permeate, when the first gaseous component is withdrawn as the retentate.
