  • Apparatus for separating a component from a fluid mixture
    Publication number: 20030209480
    Abstract: In an apparatus for separating at least one component from a fluid mixture, comprising a plurality of hollow fiber membrane frames through which a carrier fluid is conducted while the fluid mixture flows through the frames in a direction normal to the hollow fiber membranes supported in the frame, a plurality of frames are stacked on top of one another and shaped so that, together, they form a sealed tubular structure for guiding the fluid mixture past the hollow fiber membranes extending across the frames.

  • Method of manufacturing an integral asymmetrical membrane
    Patent number: 4933085
    Abstract: A method of manufacturing an integral asymmetrical membrane for the separation of liquid or gaseous mixtures. A membrane-forming agent in the form of a polyetherimide is mixed with a solvent that is miscible with water. The resulting mixture is introduced into or accommodated in a geometrical form. The form is then brought into contact with a precipitating agent.
