ABSTRACT:
A process for producing a gas stream containing oxygen and steam to feed a coal gasifier or other downstream process by compressing and heating a feed gas stream, and separating the heated feed gas stream into an oxygen-depleted gas stream on a retentate side of an ion transport membrane and an oxygen-containing gas stream on a permeate side. The permeate side is purged with a purge gas stream containing steam to produce a gas stream containing oxygen and steam, and at least a portion of the gas stream containing oxygen and steam is fed to the coal gasifier after blending with a pure oxygen stream recovered from the remaining portion of the purge stream or by a parallel nonpurged ion transport separator in the system to achieve the appropriate steam-to-oxygen ratio for the downstream process.
