Separation of condensable greenhouse gases containing fluorine (F-gases), i.e., SF 6 and HFCs-134a, from mixtures containing nitrogen was experimentally studied by using a porous Vycor membrane with a mean pore diameter of 4 nm. The separation principle was based on the difference in surface diffusi
