Title (DE) VERFAHREN ZUR ABTRENNUNG VON DISTICKSTOFFMONOXID AUS WASSERSTOFF, STICKSTOFFMONOXID UND DISTICKSTOFFMONOXID ENTHALTENDEN GASEN
(EN) METHOD FOR SEPARATING DINITROGEN MONOXIDE FROM GASES CONTAINING HYDROGEN, NITROGEN MONOXIDE AND DINITROGEN MONOXIDE
(FR) PROCEDE POUR SEPARER LE MONOXYDE DE DIAZOTE DE GAZ CONTENANT DE L'HYDROGENE, DU MONOXYDE D'AZOTE ET DU MONOXYDE DE DIAZOTE
Abstract: front page image
(DE)Verfahren zur Abtrennung von Distickstoffmonoxid aus Wasserstoff, Stickstoffmonoxid und Distickstoffmonoxid enthaltenden Gasen, dadurch gekennzeichnet, dass man ein Wasserstoff, Stickstoffmonoxid und Distickstoffmonoxid enthaltenden Gas (I) mittels einer semipermeablen Membran in ein Permeat (II) enthaltend einen höheren Volumenanteil an Distickstoffmonoxid als Gas (I) und ein Retentat (III) enthaltend einen geringeren Volumenanteil an Distickstoffmonoxid als Gas (I) auftrennt.
(EN)The invention relates to a method for separating dinitrogen monoxide from gases containing hydrogen, nitrogen monoxide and dinitrogen monoxide, characterised in that a gas (I) which contains hydrogen, nitrogen monoxide and dinitrogen monoxide is separated by a semi-permeable membrane into a permeate (II) containing a large volume proportion of dinitrogen monoxide as a gas (I) and a retentate (III) containing a lower volume proportion of dinitrogen monoxide as a gas (I).
(FR)L'invention, qui concerne un procédé pour séparer le monoxyde de diazote de gaz contenant de l'hydrogène, du monoxyde d'azote et du monoxyde de diazote, est caractérisée en ce qu'un gaz (I) contenant de l'hydrogène, du monoxyde d'azote et du monoxyde de diazote est divisé, au moyen d'une membrane semiperméable, en un perméat (II), contenant une grande part volumique de monoxyde de diazote comme gaz (I), et en un rétentat (III), contenant une faible part volumique de monoxyde de diazote comme gaz (I).
