Abstract
A process and installation for the adsorptive separation, in an adsorption olumn, of krypton from a gas mixture containing, in particular, nitrogen in addition to the krypton. The adsorption column is filled with an adsorption medium which adsorbs krypton and nitrogen over a length L extending in the direction of the inflowing gas mixture. After the adsorption of the gas components in the adsorptive column, the adsorption medium is desorbed in the following process step through the intermediary of a gaseous scavenging medium. The scavenging medium flows through the adsorption column in the same direction in which the gas mixture was introduced into the adsorption column during the first process step. The adsorption medium is charged with krypton commencing from the gas inlet of the adsorption column over only such a partial length L.sub.O of the entire column length L, that during the desorption of the adsorption column with the scavenging medium there is separately removable from each other at the gas discharge of the adsorption column, initially only nitrogen, and later on krypton.
