Abstract
An improved method for removing a component from a fluid mixture by transport of the component through an immobilized liquid membrane is described. The method includes introducing fresh membrane liquid into a first region of the membrane to effect emission of at least partially deactivated liquid from a second region of the membrane, thereby restoring or maintaining the separation efficiency of the membrane. Also described is an improved packaged membrane system including a plurality of at least partially spaced immobilized liquid membranes disposed in generally parallel surface-to-surface array to define both a first group of flow volumes and a second group of flow volumes alternating between the first group. Screens for spacing apart adjacent membranes are disposed in each of the flow volumes of at least one of the flow volume groups. Frames define the periphery of the flow volumes and flow passages provide separate access to and egress from the flow volumes in the two groups. Structure is provided for contacting fresh membrane liquid with first regions of the membranes. The structure is preferably a wall defining a chamber into which the first regions extend.
