    ABSTRACT:
    The decreasing of CO2 emissions on the ironmaking industries is a challenging issue. The massive use of granulated biomass and biogas in the iron ore sintering process are promising technological solutions to mitigate the environmental impacts on the steel plant. We focused on the development of a computational tool to analyze and suggest new practices for the sintering process using an integrated modeling approach by applying the multiphase and multicomponent theory. New phases, chemical species and rate equations are included. The model predictions were confronted with industrial data showing good adherence. New scenarios for utilizing the combined technologies of granulated biomass and biogas injection are investigated. The model predictions indicated that the high performance of the process with suitable sinter quality could be achieved. The sintering process fully operating with renewable energy sources is demonstrated.
