Abstract

An apparatus and to a method for producing krypton and xenon by separating air by cryogenic distillation and in particular to a method for separating gasses from air using internal compression (in which the gaseous oxygen is produced by vaporization under pressure in the exchange line) where a krypton/xenon mixture is extracted is provided.
