METHOD OF GAS LIQUEFACTION AND SEPARATION Russian patent published in 2010 - IPC F25J3/06 

FIELD: power engineering.

SUBSTANCE: method of liquefaction and separation of gas consists in supplying flows of gas into main subsonic or supersonic nozzles. The nozzles consist of one or several parts. Further, the method implies swirling one or several parts of a flow around additional subsonic or supersonic parts of the main nozzle wholly or partially arranged in the main nozzle. Outputs of the additional nozzles are placed in the subsonic or supersonic parts of the main nozzle. All parts of the gas flow are simultaneously supplied into the main nozzle. Gas-liquid composition enriched with target components is withdrawn from gas mixture stripped by target components. The main nozzle ensures expansion of gas to static pressure and static temperature corresponding to condensation of gas or its target components. Swirled and not swirled gas flows are supplied via additional nozzles maintaining pressure at outlets of additional nozzles sufficient for gas descending from them in the main nozzle.

EFFECT: increased efficiency of separation eliminating effects provoking flow mixing in places of separated component withdrawal.
