  • Patent number: 5755840
    Abstract: A process for providing oxygen to a feed gas wherein the oxygen is first absorbed from an oxygen-containing gas (e.g. air) and then desorbed into the feed gas (e.g. natural gas). The oxygen is adsorbed from air by passing the air in contact with an oxygen-sorbent material (e.g. a solid-state, lithium cyanocobaltate) until the sorbent-material is substantially saturated after which the feed gas is passed in contact with the sorbent material to desorb the oxygen into the feed gas.
