ABSTRACT:
A method for extracting oxygen from a fluid environment, which comprises the steps of (1) contacting a first fluid environment containing oxygen with a first surface of a first oxygen permeable membrane having a first and a second surface, wherein the membrane separates the environment from an interior space of a closed container, (2) transporting a carrier fluid into contact with the second surface of the membrane, wherein the carrier fluid is confined in the closed container and the carrier fluid contains a binding-state oxygen carrier, whereby oxygen which diffuses through the membrane binds to the carrier to give a bound oxygen complex, (3) transporting the carrier fluid containing the bound oxygen complex to a first electrode compartment of an electrochemical cell which forms a second portion of the closed container, (4) electrochemically modifying the binding-state oxygen carrier to an oxidation state having less binding affinity for oxygen, thereby releasing free oxygen into the carrier fluid and producing a nonbinding-state oxygen carrier, (5) removing oxygen from the carrier fluid, (6) transporting the carrier fluid containing the nonbinding-state oxygen carrier to a second electrode compartment of an electrochemical cell which forms a third portion of the closed container, and (7) electrochemically modifying the nonbinding-state oxygen carrier to the binding-state oxygen carrier, is disclosed along with an apparatus useful for carrying out the method of the invention.
