Driving Energy Efficiency in Heavy Industries – Analysis - IEA

The powder coal reacts with the molten ore to produce liquid iron that is the base material to produce high quality steel. The use of pure oxygen makes the process well suited to integrate CCUS as it generates a high concentration of CO 2 offgas and emissions are delivered in a single stack (a standard steel mill plant has several emission points).

iron ore as carbon is more reactive than iron (Fe). In nature, iron exists as oxides, iron ore. To produce steel products, oxygen must be removed (= reduced) from iron ore. The use of carbon (coal) is the best, stable, cost-effective method for reducing iron ore in large quantities. The reaction, however, emits CO2. Reduction Melting Refining ...
