using hbi in blast furnaces - midrex technologies, inc

The interim technology relies on the direct reduction (DR) process where natural gas is used to produce direct reduced iron (DRI) in the densified form of hot briquetted iron (HBI). With respect to the core process of DR, this results in a CO 2 reduction of 50% when compared to the BF process. Depending on the generation capacity for power used to melt scrap in the electric arc furnace (EAF), a reduction of …
