FIELD: purification and separation of krypton xenon concentrate. SUBSTANCE: proposed method includes separation of krypton xenon concentrate in preliminary separation column into krypton and xenon fractions, additional purification of each fraction by from involatile contaminants by rectification and additional separation of krypton from blow-off gases of krypton column. Forming of phlegm in condensers-evaporators is performed under conditions excluding forming of solid phase and placing of rectifying columns in operation is performed at delivery of krypton to contact space. Specification contains description of device proposed for realization of this method. EFFECT: enhanced economical efficiency. 4 cl, 1 dwg
