Recovering oxygen used e.g. in industry comprises collecting a gas mixture produced as waste gas during industrial process, and introducing to air decomposition device to recover oxygen

摘要

Recovering oxygen comprises collecting a gas mixture produced as a waste gas during an industrial process; and introducing to an air decomposition device (5) to recover the oxygen. An independent claim is also included for a apparatus for recovering oxygen comprising a feed for oxygen-rich gas, a gas purification device (4) connected to the feed, and an air decomposition device (5) joined to the gas purification device.
