Abstract: The invention relates to cryogenic engineering. The inventive device for liquefying and separating gas and for releasing one or more gases from a mixture thereof, comprises, in series axially positioned, a prechamber (1) with gas flow whirling means (2) arranged therein, a subsonic or supersonic nozzle (3) with a working segment (4), which is abutted thereto and to which liquid phase extracting means (5) is connected, and a subsonic diffuser (7) or the combination of a supersonic (6) and the subsonic diffuser (7). The nozzle (3) is designed in such a way that it makes it possible to achieve the ratios, between the inlet and outlet cross-sectional areas and the minimum cross-section thereof, which provides, at the output of the nozzle, a statical pressure and a statical temperature corresponding to the conditions of condensation of gas or target gas mixture components. The length of the working segment (4) is selected according to a condition of forming condensate drops with a size greater than 0.

Abstract: An apparatus for liquefying a gas has a nozzle having a convergent nozzle portion and a nozzle throat, and a divergent nozzle portion (in the case of supersonic flow), and a working section. Vanes or another mechanism for creating a swirl velocity are connected to the nozzle, to create a strong swirl velocity in gas fed to the nozzle. In the nozzle, the gas adiabatically expands, gas velocity increases and gas temperature drops, to promote the condensation of gas with formation of droplets. The gas then passes through a working section having a wall, whereby further condensation of at least a portion of the gas flow occurs and droplets of condensed gas grow. Centrifugal effects generated by the swirl velocity drive the droplets towards the wall of the working section. Condensed liquid gas droplets are separated from remaining gas in the gaseous state at least adjacent the wall of the working section.
