Unit for Passive Transfer of CO2 from Flue Gas or Ambient Air

Abstract:

A passive gas exchange transfer apparatus for exchanging carbon dioxide from a flue gas to a water supply is disclosed. The apparatus includes several upper rods and several lower rods to hold a membrane in place. The membrane provides increased surface area for the gas and the water to meet. The upper rods may be the source of the water supply, and the lower rods may be the source of the gas. The upper rods may disperse the water onto one side of the membrane, and the lower rods may disperse the gas onto the other side. The two may therefore meet at the surface created by the membrane as gravity draws the water downward, and convection draws the gas upward.
