CO₂ Emissions from BF-BOF and EAF Steelmaking Based on Material Flow Analysis

Abstract:

In order to calculate the amount of CO2 emissions from the iron and steel making in China, carbon flows in two iron and steel enterprises were investigated with Material Flow Analysis, through the production data and sampling of materials from each enterprise in this paper. Results show that the main carbon sources of CO2 emissions in blast furnace-basic oxygen furnace (BF-BOF) steelmaking are fossil fuel, and fossil fuel in electricity furnace (EAF) steelmaking account for 33% of the total carbon sources; The amount of CO2 emission of per ton crude steel from the BF-BOF steelmaking and EAF steelmaking is 1149.7 and 46.6 kg, respectively.
