METHOD OF USING AN OXYGEN WASTE STREAM AS AN OXIDIZER FEED GAS STREAM

摘要

A method for producing carbon dioxide using the waste gas oxygen stream from an air separation unit producing nitrogen as the oxygen feed. The oxygen is fed to an autothermal reformation or partial oxidation unit to produce synthesis gas which is subjected to a shift reaction to produce hydrogen and carbon dioxide. The carbon dioxide is separated and recovered and can be employed in an enhanced oil recovery operation.
