Abstract:
A method for producing iron comprising:(A) generating synthesis gas by passing feed air into an air separation plant, separating the feed air in the separation plant to produce oxygen, and reacting oxygen from the air separation plant with hydrocarbon fluid to effect the said generation of the synthesis gas, and passing the synthesis gas into a reactor vessel;(B) providing iron ore into the reactor vessel and reacting the iron ore with the synthesis gas within the reactor vessel to produce iron and reactor off-gas comprising carbon monoxide, hydrogen, carbon dioxide and water vapor;(C) recovering iron from the reactor vessel;(D) removing at least some of the water vapor from the reactor off-gas to produce drier off-gas; and(E) combusting the drier off-gas in a gas turbine to produce power.
