<p>Helium product fraction production involves subjecting a residue gas fraction (4) of an adsorption process (A) in a diaphragm separation process (M). The helium-rich fraction (5,6) is supplied to the adsorption process. The diaphragm separation process is operated at 10->2 and 10->1 bar pressure. An independent claim is also included for a device for producing a helium product fraction.</p> |
