schon verflüssigten Gas geleitet und gezwungen wird, darin in Form von Blasen aufzusteigen, wobei es äussere Arbeit leistet. Durch die dabei entstehende innige Berührung des Gases mit der Flüssigkeit tritt gleichzeitig eine Trennung bei der Mittel in ihre Bestandteile ein ; die Fltissigkeitsteile mit niederem Siedepunkte nehmen Wärme von dorn Gase auf und verdampfen, während dafür der leichter verfliissigbare Teil des Gases durch

Handelt es sich beispielsweise um die Verflüssigung und Trennung der atmosphärischen Luft in Sauerstoff und Stickstoff, so lässt man vorgekühlte Pressluft in einer Säule ver-

Teile der Flüssigkeit mit tieferem Siedepunkt verdampfen.
Das Wesen der Erfindung besteht also darin, dass ein zu trennendes, entsprechend vorgekühltes Mischgas und eine vergasbare Mischflüssigkeit dadurch einem Trennungsprozess unterworfen werden, dass die in die Flüssigkeit eingeführten Gasblasen eine Rektifikation einteilen, weil sie, unter Druck eingeführt, gezwungen sind, durch Verdrängen der Flüssigkeit

Gases mit der Flüssigkeit übertragen die Gasblasen die mitgeführte Wärme vorzugsweise an den tiefer siedenden Bestandteil der Flüssigkeit, so dass dieser als Gas abziehen kann.
Im Austausch daftir wird ein Teil des höher siedenden Bestandteiles des Mischgases ver-

Process for the liquefaction and separation of gas mixtures.
EMI1.1
gas that has already been liquefied is passed and forced to rise in it in the form of bubbles, doing external work. As a result of the intimate contact of the gas with the liquid, a separation of the agent into its components occurs at the same time; the parts of the liquid with a lower boiling point absorb heat from the gases and evaporate, while the more easily liquid part of the gas passes through
EMI1.2
If, for example, it is a matter of liquefying and separating atmospheric air into oxygen and nitrogen, precooled compressed air is left in a column.
EMI1.3
Part of the liquid with a lower boiling point will evaporate.
The essence of the invention consists in the fact that a mixed gas to be separated, appropriately pre-cooled, and a gasifiable mixed liquid are subjected to a separation process in that the gas bubbles introduced into the liquid divide a rectification because, when introduced under pressure, they are forced by displacing the liquid
EMI1.4
Gas with the liquid, the gas bubbles transfer the heat carried along preferably to the lower-boiling component of the liquid so that it can be withdrawn as a gas.
In exchange for this, part of the higher-boiling component of the mixed gas is
EMI1.5
while the cold store of the separately withdrawn exhaust gas or the liquid is transferred to the new hinxuniessonde, compressed gas.
In Fig. 1 of the drawing is a serving to carry out this method before
