Greenhouse Gas Emissions and Energy Consumption of Ironmaking Processes

  • Chapter
  • First Online:

Abstract

The emissions of greenhouse gases (GHG), mainly carbon dioxide, and energy consumption levels of a number of ironmaking processes including several new technologies that are currently under development worldwide are analyzed and compared. In terms of total emissions of greenhouse gas, energy consumption is important because the production of fuels and energy indirectly adds to the total amount of emissions. The relevant levels of emissions and energy requirements are compared with those of an average blast furnace, which is currently the dominant ironmaking process. The article will also discuss the needs for alternate ironmaking processes and present the descriptions of major alternate ironmaking processes, including important novel technologies under development. Finally, different methods for calculating process energy vs total energy requirement in ironmaking will be discussed.
