Zusammenfassung:	1452242 Oxygen enrichment of gases BERGWERKSVERBAND GmbH 2 Jan 1975 [9 Jan 1974] 76/75 Heading B1L The oxygen content of a gas e.g. air is enriched by passing the feed gas through a molecular sieve coke absorber until the discharging gas has approximately the composition of the feed gas, thereafter passing a further gas having a higher O 2 content than the feed gas through the absorber to displace a gas having an O 2 content lower than the further gas and thereafter separating three O 2 -rich fractions by means of a vacuum pump; the first and third fractions having a lower O 2 content than the second. The first and third fractions may be employed as said further gas.
