  1. 1. Integrating biomass gasification with electric arc furnace steel making

    University essay from KTH/Energiprocesser

    Author : Filippa Andersson; [2023]
    Keywords : Electric arc furnace; EAF off-gas; gasification; CCU; process integration; Ljusbågsugn avgasrök; ljusbågsugn; förgasning; kolavskiljning; process integration;

    Abstract : Utsläppen av växthusgaser ökar över hela världen och nya tekniker används för att minska utsläppen. 7% av utsläppen kommer från stålsektorn. 25% av världens stålproduktion görs via återvinningstekniken ljusbågsugn. Genom återvinningsprocessen släpps det ut 500kg CO2 per ton producerat flytande stål. READ MORE

  3. 2. Analysis on copper, lead and tin removal in steel scrap sorting : Technologies involved, environmental considerations and economic aspects

    Abstract : Steel is one of the most essential metals in the world, and it plays a vital role in various industries. The growing demand for steel has resulted in increased CO2 emissions, with the steel industry contributing to approximately 7% of global emissions of carbon dioxide. READ MORE

  5. 4. Heat recovery from low emission steel production through electrolysis and hydrogen reduction

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Sofia Kongshöj; [2023]
    Keywords : Electrolysis; H2 Green Steel H2GS ; waste heat recovery; district heating.; Earth and Environmental Sciences;

    Abstract : The steel industry is a large emitter of carbon dioxide and uses a lot of energy. Because of an increased awareness of the detrimental effects of climate change, research in alternative ways to operate steel plants have been made. It is now possible to build plants with far less emissions by using electrolysis and hydrogen reduction. READ MORE

  6. 5. Theoretical Considerations and Experimental Observations on Heat Transfer in Hydrogen Direct Reduced Iron

    University essay from KTH/Materialvetenskap

    Author : Felix Göttfert; [2023]
