Process for separating oxygen from a gas mixture using a solid electrolyte membrane |
摘要 |
<p>A process for removing oxygen from a feed gas stream to produce an oxygen-depleted retentate gas stream by supplying the feed gas stream to a bulk oxygen separation system for removing oxygen to produce an oxygen-depleted crude product gas stream and a first oxygen-containing permeate effluent stream, and supplying the oxygen-depleted crude product gas stream to a separator having a primary ion transport membrane to produce a second permeate effluent stream and the oxygen-depleted retentate gas stream. A reactive purge gas is added to react with a portion of the oxygen permeating through the primary ion transport membrane and purge the permeate side of the primary ion transport membrane, and/or a recycle gas stream comprising at least a portion of one gas stream produced during the process is added to at least one other of the gas streams. <IMAGE></p> |
