Several grades of treated wood chips are available, based on iron oxide content. The most common grades are 6.5-, 9.0-, 15.0-, and 20-lb iron oxide/bushel. The chips are contained in a vessel, and sour gas flows through the bed and reacts with the ferric oxide. Figure 7-3 shows a typical vessel for the iron sponge process.

The HYBRIT process involves removing the oxygen from the iron ore using hydrogen. The reduction occurs at a lower temperature and the result is so-called sponge iron (direct reduced iron). The sponge iron is smelted in a furnace, powered by electricity. The furnace is called an Electric Arc Furnace (EAF).

The metallic iron in this process is produced by the reduction of iron oxide below the fusion temperature of iron ore (1535 deg C) by utilizing carbonaceous material present in the non-coking coal. As the iron ore is in direct contact with the reducing agent throughout the reduction process, it is often termed as direct reduced iron (DRI).
