Abstract:
1. A device for gas liquefaction or separation of one or more gases from their mixture, comprising the following coaxially installed components: a premix chamber ( 1 ) with swirling means ( 2 ) for swirling a gas flow; a main subsonic or supersonic nozzle ( 3 ) with a working section ( 4 ) attached thereto, separating means ( 5 ) for separating the liquid phase being attached to the working section, a subsonic diffuser ( 7 ) or a combination of a supersonic diffuser ( 6 ) and a subsonic diffuser ( 7 ); the device being arranged such that the nozzle ( 3 ) being made with relationships between inlet and outlet cross-sectional areas and minimum cross section of the nozzle ( 3 ) that ensure a static pressure and a static temperature at the nozzle outlet, which comply with the condition of condensation of a gas or the gas' target components, a length of the working section ( 4 ) ensures formation of condensate droplets having a size greater than 0.5 microns and their drift from the axial area of the working section ( 4 ) toward the walls of droplet separating means for separating droplets, and the aperture angle of the working section ( 4 ) ensures maintaining conditions for gas or the gas' target component condensation; the said device being provided with an additional subsonic or supersonic nozzle ( 8 ) arranged in the premix chamber ( 1 ), such that the outlet of the additional nozzle ( 8 ) is arranged in the subsonic portion or in the supersonic portion of the main nozzle ( 3 ).
