Abstract:
Apparatus for performing membrane gas/liquid absorption at elevated pressure, comprising:a pressure vessel (1) which encloses an essentially closed chamber (2); inlet and outlet means respectively, for supplying (3a) and discharging (4a) a gas phase to/from said essentially closed chamber (2); a membrane unit (5) disposed in said essentially closed chamber (2), comprising at least one membrane element (6) which defines a feed-through channel (7); inlet and outlet means respectively, for supplying (8a) or discharging (9a) a liquid phase to the membrane unit (5), such that the liquid phase can be passed from said inlet means (8a) through said feed-through channel (7) to said outlet means (9a); wherein said pressure vessel (1), said inlet means (3a) and said outlet means (4a) and said membrane unit (5) are provided in such a way in said essentially closed chamber (2) that the gas phase can be directed past said membrane element (6) in a flow direction essentially perpendicular to the flow direction of the liquid phase through said membrane element (6), exchange being able to take place of components to be absorbed between the gas phase and the liquid phase through the wall of said membrane element (6).
