Modeling MIDREX Based Process Configurations for Energy and Emission Analysis

steel research international, 2017
A natural gas (NG) based MIDREX shaft model has been developed and validated for emission and energy estimation for crude steel production. The model is extended to hydrogen rich alternative fuels namely Coke Oven Gas (COG) and Syngas from coal gasification to predict emissions and energy for producing crude steel.
