Estimation of the Emissions of CO2, SOx, and NOx of Steel Alloys

  • K. Halada (a1), K. Ijima (a1) and K. Yagi (a1)


The emissions of CO2, SOx, and NOx of various steel alloys in the production stage were calculated by using the unit requirement of each subsystem of the steel-making process, in order to compare the superiority from the viewpoint of the environmental issue among various types of steel alloys. As steel production is a typical integrated system with multiproducts, allocation of emissions to each product, effect of the composition, and sharing the load by the by-product gases are considered. Calculated values of emission were arranged for fifteen kinds of finished steel products and for arbitrary contents of alloying elements.
