APPARATUS FOR EXTRACTION OF A GAS FROM A GASEOUS MEDIUM FLOW AND METHOD FOR MANUFACTURING THE SAME

Apparatus (1) for extraction of at least one gas from a gaseous medium flow, comprising at least one membrane contactor (2) containing at least one hollow fiber membrane, the membrane contactor (2) having a medium side (3) and an absorber side (4) which is situated opposite to the medium side (3), at least one housing (5) which 5 is impermeable at least to liquids, the membrane contactor (2) extending inside the housing, at least one medium pipe (6) for supplying an untreated medium flow to the medium side (3) of the membrane contactor (2) and for discharging a treated medium flow away from the membrane contactor (2), at least one absorber pipe (7) for supplying an absorption liquid to the absorber side (4) of the membrane contactor (2) and discharging said absorption liquid away from said membrane contactor (2), respectively, wherein the membrane contactor (2) comprises a plurality of pores (8), which permit at least the one gas to be extracted from the medium flow to pass through the membrane contactor (2) from its medium side (3) to its absorber side (4), the membrane contactor (2) otherwise being arranged in such a way that a fluidic connection 15 between its medium side (3) and its absorber side (4) is prevented, wherein the membrane contactor (2) is provided with a coating (9) on at least either one of its sides (3, 4), the coating (9) preventing a direct contact of the absorption liquid with the gaseous medium flow In order to provide an apparatus for extraction of gas from a gaseous medium flow that's construction is cheaper and simpler than the one known in the art, it is proposed according to the invention to make the membrane contactor (2) from a hydrophilic material. L'invention concerne également un appareil (1) pour l'extraction d'au moins un gaz à partir d'un flux de milieu gazeux, comprenant au moins un contacteur à membrane (2) contenant au moins une membrane à fibres creuses, le contacteur à membrane (2) ayant un côté milieu (3) et un côté absorbeur (4) qui est situé à l'opposé du côté milieu (3), au moins un boîtier (5) qui est imperméable au moins aux liquides, le contacteur à membrane (2) s'étendant à l'intérieur du boîtier, au moins un tuyau de milieu (6) destiné à amener un flux de milieu non traité vers le côté milieu (3) du contacteur à membrane (2) et à évacuer un flux de milieu traité à l'opposé du contacteur à membrane (2), au moins un tuyau d'absorption (7) pour fournir un liquide d'absorption au côté absorbeur (4) du contacteu
