Resumo
Hatch investigated the hypothetical coupling of heat recovery cokemaking, ITmk3® ironmaking and EAF steelmaking to exploit synergies between these three processes and to use this to reduce the carbon footprint to produce hot rolled coil compared to the traditional blast furnace route. To provide a fair comparison of CO2 emissions, the consumption of all carbon produced was accounted for including coke sales to an existing blast furnace and the additional hot rolled coil that would be produced. Hatch's 4-quadrant analysis (4QA) methodology was used to compare the overall environmental footprint and capital cost to identify the most sustainable process route. An analysis of the operating costs indicated that the proposed plant arrangement offered financial merit reducing the cost to produce hot rolled steel compared to the blast furnace route. This unique coupling of new coke and ironmaking technologies could be implemented on a stand-alone basis or integrated into an existing steel works to eliminate smaller blast furnaces and outdated byproduct coke plants.
