  1. 11. Integration of SMRs with Steel Industry

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :David Carlsén; [2022]
    Nyckelord :Small Modular Reactor; SMR; Xe-100; Pink Hydrogen; Electrolysis; SOEC; Steel; Iron; DRI; DRP; Energy; Industry; Transition; Technology and Engineering; Chemistry; Earth and Environmental Sciences;

    Sammanfattning : The steel industry is with its high emissions an important sector to transform from fossil-fueled to fossil-free. In recent years, the technology development has accelerated quickly regarding iron ore reduction using hydrogen produced from electrolysis within the EL-DRP-EAF steel production route. LÄS MER

  3. 12. Influence of coal particle sizes on the mechanical strength of iron-carbon briquettes : With focus on steelmaking applications

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Daniel Zaharije Hodgson; Efe Karadag; Maxime Pierre Jean-Claude Saillen; [2022]
    Nyckelord :;

    Sammanfattning : Replacing fossil carbon materials with renewable biocarbon is one way to reduce the net carbon dioxide emissions of the iron and steelmaking industry. Carburization is an important application in the electric arc furnace (EAF), and is mostly achieved by adding fossil-based carbon materials into the melt today. LÄS MER

  4. 13. Integrating CO2 Utilisation and Biomass Gasification with Steel-making Electric Arc Furnaces (EAF)

    Master-uppsats, KTH/Energiprocesser

    Författare :Adel Mokhtari; [2022]
    Nyckelord :biomass gasification; carbon capture and utilization CCU ; process integration; electric arc furnace EAF ; EAF off-gas;

    Sammanfattning : Without a doubt, there is a consensus around the international community which suggests that our current way of life is unsustainable for a healthy planet, society and economy. One focal point that should be taken deeply into consideration is the steel industry as, globally, it accounts for 8% of global emissions. LÄS MER

  5. 14. Tidslinje och tecknets rörelse i finlandssvenskt teckenspråk. : En korpusbaserad studie.

    Kandidat-uppsats, Stockholms universitet/Avdelningen för teckenspråk

    Författare :Lena Wenman; [2022]
    Nyckelord :time expression; Finland-Swedish sign language; timelines; time orientation metaphor; tidsuttryck; finlandssvenskt teckenspråk; tidslinjer; tidsorienteringsmetafor;

    Sammanfattning : Teckenspråk kan uttrycka tid på olika sätt med hjälp av teckenrummet. Jag har i min studie fokuserat på hur rörelsen i tecken och medveten placering av flera tecken i teckenrummet kan kopplas till tidsbegrepp, så kallade tidslinjer. LÄS MER

  7. 15. Cost Efficient Scrap Metal Sourcing

    Master-uppsats, Lunds universitet/Teknisk logistik

    Författare :Sophia Sandström; Sofia Ivarsson; [2022]
    Nyckelord :Scrap sourcing; Scrap logistics; European scrap market; Sea freight strategies; Bulk shipping; Technology and Engineering;

    Sammanfattning : The steel industry in Sweden is responsible for 10% of the annual Swedish CO2 emissions. As a way to abate this sector, H2 Green Steel are establishing a new green steel production site in Boden. Their way of producing steel, through the EAF route and by using hydrogen-reduced DRI will reduce the CO2 emissions by over 90%. LÄS MER
