ABSTRACT:
The present invention is directed to a continuous flow method for removing oxygen from a fluid stream. The method comprises the steps of providing a fluid stream containing oxygen, causing the fluid stream to come in contact directly or indirectly, with a sufficient amount of oxygen scavenging cell membrane fragments having an electron transport system which reduces oxygen to water to catalyze the transformation of the oxygen contained in the fluid stream to water. The present invention is also directed to an apparatus for removing oxygen from a fluid stream. The apparatus is comprised of a flow through reactor chamber containing a sufficient amount of oxygen scavenging cell membrane fragments having an electron transport system which reduces oxygen to water to catalyze the transformation of oxygen present in a fluid stream to water, wherein said fragments are contained therein in a manner which allows free contact between said fragments and the fluid stream flowing therethrough or for the diffusion of the oxygen from the fluid stream across a synthetic membrane to a compartment containing the fragments where the oxygen is transformed to water. A means for introducing a fluid stream containing oxygen into said flow-through reaction chamber and a means for removing said deoxygenated fluid stream are also provided.
