Abstract

A method and an apparatus for producing air products comprising the steps of providing a feed mixture (201) comprising krypton, xenon and oxygen, introducing the feed mixture (201) into a first rectification column (121), withdrawing a first fraction (202) depleted in oxygen and enriched in krypton and xenon relative to the feed mixture (201) and a second fraction (203) enriched in oxygen and depleted in krypton and xenon relative to the feed mixture (1) from the first rectification column (121), introducing a third fraction (204) derived from the second fraction (203) into a second rectification column (125) and withdrawing a high-purity oxygen fraction (O) from the second rectification column (125).
