Patent ID: 7556675

Claim:
An ion transport membrane oxidation system comprising (a) an enclosure having an interior and an interior surface, inlet piping having an internal surface and adapted to introduce a heated feed gas into the interior of the enclosure, and outlet piping adapted to withdraw a synthesis gas product from the interior of the enclosure; (b) one or more planar ion transport membrane modules disposed in the interior of the enclosure, each membrane module comprising mixed metal oxide material; and (c) a preheater adapted to heat a feed gas to provide the heated feed gas to the inlet piping of the enclosure, wherein the enclosure is adapted to place the heated feed gas in contact with the mixed metal oxide material, and wherein the preheater comprises an interior surface; wherein either (1) any of the interior surfaces of the enclosure, the inlet piping, and the preheater are lined with a copper-containing metal lining, or (2) any of the interior surfaces of the inlet piping and the preheater are lined with a copper-containing metal lining, and the enclosure comprises copper.
