Estimation of the emissions of
CO₂, SO_x,
NO_x of steel alloys
K. Halada, K. Ijima, K. Yagi
(National Research Institute for Metals)
The
emissions of CO₂, SO_x, and
NO_x of various steel alloys in the production
stage were calculated using the unit requirement of each sub-system of the
steelmaking 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
multi-products, 1) allocation of emissions to each product, 2) effect of
the composition, and 3) 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.
