A Strategy for Suppressing Carbon Dioxide Emissions from Blast Furnace Steelmaking
A process integration approach is used to estimate minimum carbon dioxide emission from a conventional steelmaking plant.A mixed integer nonlinear programming model is developed to find the optimal operational conditions and gas distribution in the system considering top gas recycling with preheating for nitrogen-free blast furnace,different reducing agents as blast furnace injectants and fuels in power plant,such as coke oven gas,oil,natural gas,pulverized coal and biomass,and CO2 sequestration.The results show a potential of suppressing the specific emissions up to 0.2-0.6 metric ton carbon dioxide per ton liquid steel,using different fuels as the auxiliary reducing agent in the blast furnace and as external fuel in the power plant.
