Corex ProcessCosts & Benefits
|Parent Process: Smelting Reduction|
|Energy Savings Potential||
Dry fuel consumption with and without off-gas recycling is reported to be 770 kg/t-HM and 940 kg/t-HM.
|CO2 Emission Reduction Potential||
CO2 emissions per ton of combined product (hot metal + DRI) are lower by ~20% compared to blast furnace route (APP, 2010. p.56)
Total CO2 emissions for steel produced with 60% hot metal from Corex and 40% DRI is reported to be around 3.78 t/t-steel (US DOE, 2003)
Reported capital costs were in the range of €195 per ton of annual production (IPPC, 2012. p. 528).
Capital and operational costs for producing steel with 60% Corex hot metal and 40% DRI is reported to be $373.5 and $218.3 per ton of steel, respectively (US DOE, 2003. p.4/4)
