Abstract:
In a partial oxidation process for partially oxidizing a hydrocarbonaceous feedstock to produce a high temperature, high pressure synthesis gas containing hydrogen and carbon monoxide, wherein said process comprises the partial oxidation of a hydrocarbonaceous feedstock to produce a synthesis gas at a high pressure, cooling and scrubbing the synthesis gas to produce a clean synthesis gas, heating the clean synthesis gas, reacting the heated synthesis gas in a shift reaction to increase the amount of hydrogen contained therein, cooling the hydrogen enriched synthesis gas and removing acid gases from the hydrogen enriched synthesis gas; the improvement which comprises:integrating the partial oxidation process with a reaction system for the direct reduction of iron, wherein an ion ore feed is contacted with a reducing gas at a mean operating gas pressure to produce elemental iron, and wherein at least a portion of the reducing gas for the direct reduction of iron is supplied by the high pressure synthesis gas produced from the partial oxidation process, and wherein the synthesis gas has been expanded to lower its pressure to substantially the mean operating gas pressure used in the reaction for the direct reduction of iron, thereby utilizing at least a portion of the synthesis gas as the reducing gas for the direct reduction of iron.
