FIELD: separation of gaseous mixture components. SUBSTANCE: partial pressure of gaseous components in a mixture is so varied that at the moment of passage of the nozzle by the gas flow the condensation point of the component, having at normal pressure a lower condensation point, would be higher than the condensation point of the component, having at normal pressure a higher condensation point. Besides, a nozzle geometry is selected providing for retention in the process of cooling of the component with a higher condensation point in the gaseous phase at normal pressure and liquefaction of the component with a lower condensation point at normal pressure in the amount sufficient for solution of the gaseous phase of the component with a higher condensation point in it. EFFECT: enhanced efficiency of separation of gaseous mixtures due to their liquefaction. 2 dwg, 2 ex, 1 tbl |
