METHOD OF SEPARATING OFF TRACE COMPONENTS FROM A FRACTION CONTAINING AT LEAST NITROGEN AND HELIUM |
摘要 |
A method is described for separating off trace components from a fraction (1) containing at least nitrogen and helium, wherein this fraction is partially condensed (E) before enrichment of the helium. The partially condensed fraction (2) is fed at least in part to at least one separation column (T) and separated therein into a helium-rich gas fraction (6) and a nitrogen-rich liquid fraction which also contains the unwanted trace components (5).
