GASIFICATION AND THE MIDREX? DIRECT REDUCTION

The chemical formulas for the iron ore reduction reactions are: Fe2O3 + 3 CO ! 2 Fe + 3 CO2 Fe2O3 + 3 H2 ! 2 Fe + 3 H2O Obviously, a DRI plant needs H2 and CO These are called the reducing gases In all existing DRI plants, these gases are generated from either natural gas or coal(PDF) The Midrex Process and the Nigerian Steel Industry ,The goal of producing steel in Nigeria from iron ore was made possible through the Midrex Process based Direct Reduction plant at the Delta Steel Company The iron ore was originally imported from Liberia and its parameters formed the basis of theMIDREX Processes - 神戸製鋼所,reduced ironmaking plant where resources such as natural gas, iron ore and power are less costly The product, hot briquette iron (hereinafter referred to as HBI ), can be exported by sea to steelmaking plants and rolling mills in other countries This has expanded the number of potential sites for MIDREX plants all over the world 1)
