Abstract (en)
[origin: WO9601679A1] A method for producing high-purity nitrogen by separating a nitrogen- and oxygen-containing gas mixture in a permeation separation apparatus (9) and feeding the resulting nitrogen-enriched gas into an adsorption apparatus (A, B). Part of the residual gas in the adsorption apparatus may be recycled by mixing it with the mixture to be separated or using it as a scavenging gas in the permeation separation apparatus (9).
