FIELD: separation of air components by forcing mixture through vortex tube. SUBSTANCE: invention can be used to increase share of oxygen in combustion chambers, in medicine. Oxygen is transferred to ozone which has higher critical temperature that other gases ahead of entrance to tube to improve separation of mixture. Extracted ozone may be used directly or may be decomposed to gaseous oxygen. EFFECT: improved efficiency of air separation. 4 cl, 2 dwg
