  • Patent number: 5876486
    Abstract: The invention relates to a method and to an apparatus for continuously removing metabolically produced carbon dioxide from respired air, such as the air found in life support systems or cabin circulating systems, using two sets of hollow fibers disposed in a flowing, carbon dioxide-selective liquid membrane. The carbon dioxide-containing respired air flows through the first set of hollow fibers and the second set of hollow fibers serves to carry away the permeate stream.
