Abstract

A process for recovering SF6 from a gas is provided.
The process includes the step of contacting a gas stream comprising SF6 and at least one of N2, O2, CO2, and H2O with a membrane in at least one membrane separation unit at conditions effective to obtain a retentate stream rich in SF6 and a permeate stream rich in at least one of N2, O2, CO2, ancL H2O.
A process for forming solidified Mg metal is also provided. The process includes recovering and/or recycling of SF6 and/or CO2.
