 richtung nötige Kälte liefert, und durchströmt dann die Rohre   4'des   Austauschers 4, wo er die Kondensation des Azetylens bewirkt und sich dabei erwärmt, worauf er durch die Leitung 17 über den Austauscher 14 zum Verdichter 13 zurückkehrt. 



   Nach einer gewissen Zeit werden die Umschaltventile 3, 18 und 19 sowie das   Entspannungsventil 16   selbsttätig umgeschaltet. Auf diese Weise wird das Gasgemisch in den als Kondensator arbeitenden Austauscher 5 geleitet. Der Austauscher 4 arbeitet dann als Verdampfer. Der Wasserstoff tritt dann bei 12 und das Azetylen bei 8 aus. Gleichzeitig wird der Kreislauf des Hilfsmittels umgeschaltet und erfolgt dann in der Richtung 14-17, 4, 5, 15 und   14.   



   Bei dieser Vorrichtung ist jede Gefahr einer Verstopfung vermieden, da das Azetylen die Rohre stets im kalten Zustand umströmt. Anderseits erfolgt der   Wärmeaustausch   in den Kondensatoren zwischen Gasen von sehr verschiedenen Drücken, wodurch die   Kälteübertragung wesentlich erleichtert   wird. 



   Der Hilfskreislauf dient also hier nicht nur   als Übertragungsmittel,   sondern gleichzeitig auch zur Abkühlung der Vorrichtung bei der Inbetriebsetzung. Während des Betriebes werden die unvermeidlichen Kälteverluste durch freie Entspannung oder durch Entspannung mit äusserer Arbeitsleistung in

Man kann die zu behandelnden Gase auch unter atmosphärischen oder unter noch geringeren Drücken verwenden, um jede Gefahr einer Bildung von flüssigem Azetylen zu vermeiden.

1. Verfahren zur Wiedergewinnung eines Bestandteiles eines Gasgemisches durch Kälte unter Kondensation und Verdampfung bzw. Sublimation dieses Bestandteiles in zwei abwechselnd als Kondensator und als Verdampfer oder Sublimator arbeitenden Vorrichtungen, dadurch gekennzeichnet, dass man ein in einem gegebenenfalls geschlossenen Kreislauf, zweckmässig unter Druck strömende Mittel

 direction supplies the necessary cold, and then flows through the tubes 4 'of the exchanger 4, where it causes the condensation of the acetylene and warms up, whereupon it returns through the line 17 via the exchanger 14 to the compressor 13.



   After a certain time, the switching valves 3, 18 and 19 and the expansion valve 16 are switched over automatically. In this way, the gas mixture is passed into the exchanger 5 operating as a condenser. The exchanger 4 then works as an evaporator. The hydrogen then exits at 12 and the acetylene at 8. At the same time, the circuit of the aid is switched and then takes place in the directions 14-17, 4, 5, 15 and 14.



   With this device, any risk of clogging is avoided, since the acetylene always flows around the pipes in the cold state. On the other hand, the heat exchange takes place in the condensers between gases of very different pressures, which significantly facilitates the transfer of cold.



   The auxiliary circuit is used here not only as a transmission medium, but at the same time also for cooling the device when it is started up. During operation, the inevitable loss of cold through free relaxation or through relaxation with external work performance in

The gases to be treated can also be used under atmospheric or even lower pressures in order to avoid any risk of the formation of liquid acetylene.



   PATENT CLAIMS:
1. A process for the recovery of a component of a gas mixture by cold with condensation and evaporation or sublimation of this component in two devices operating alternately as a condenser and as an evaporator or sublimator, characterized in that a medium which flows in an optionally closed circuit, suitably under pressure
