Title
(DE) MEMBRANAUFBAU ZUR GASABSCHEIDUNG
(EN) MEMBRANE STRUCTURE FOR GAS SEPARATION
(FR) STRUCTURE DE MEMBRANE DESTINÉE À L'EXTRACTION DE GAZ
Abstract
(DE)
Es werden ein Membranaufbau zur Gasabscheidung, eine Entgasungsvorrichtung mit einem derartigen Membranaufbau sowie Verfahren zur Herstellung vorgeschlagen. Eine poröse Trägerschicht wird flächig mit einer dünnen Polymermembran, insbesondere aus amorphem PTFE, verbunden. Insbesondere wird die Polymermembran auf oder aus der Trägerschicht hergestellt. Dies ermöglicht einen einfachen und kostengünstigen Aufbau sowie eine effektive Gasabscheidung. Besonders bevorzugt wird die Polymermembran dadurch gebildet, daß eine Polymerlösung flüssig auf die Trägerschicht aufgebracht und eingetrocknet wird.
(EN)
A membrane structure for gas separation, a degassing device having such a membrane structure, and also method for production of the same are proposed. A porous carrier layer is joined flat to a thin polymer membrane, in particular made of amorphous PTFE. In particular, the polymer membrane is produced on or from the carrier layer. This makes possible a simple and inexpensive structure and also an effective gas separation. Particularly preferably, the polymer membrane is formed by applying a polymer solution in the liquid state to the carrier layer and drying it.
(FR)
L'invention concerne une structure de membrane destinée à l'extraction de gaz, un dispositif d'extraction de gaz comprenant une structure de membrane de ce type et des procédés de production. Une couche support est en liaison surfacique avec une mince membrane polymère réalisée notamment en PTFE amorphe. La membrane polymère est notamment formée sur ou constituée de la couche support. Cela permet d'obtenir une structure simple et économique et une extraction de gaz efficace. De préférence, la membrane polymère est réalisée par application d'une solution polymère liquide sur la couche support puis par séchage.
