ABSTRACT:
A process for oxygen-enriching a first feed gas stream be fed into a furnace by utilizing an oxygen-enriched gas stream from a second feed gas stream, wherein the first feed gas stream is compressed and then heated prior to injection into the furnace. The second feed gas stream is separated using an ion transport module containing an ion transport membrane having a retentate side and a permeate side to produce an oxygen-depleted gas stream on the retentate side and the pure oxygen gas stream or the oxygen-enriched gas stream on the permeate side. The pure oxygen gas stream or the oxygen-enriched gas stream is added to the first feed gas stream at any location before the first feed gas stream enters the furnace.
