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

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

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

    Sammanfattning : 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. LÄS MER

  3. 2. Neutralization of acidic wastewaters with the use of landfilled Electric Arc Furnace (EAF) high-alloyed stainless-steel slag : An upscale trial of the NEUTRALSYRA project

    Master-uppsats, KTH/Materialvetenskap

    Författare :Rahul Puthucode; [2019]
    Nyckelord :Landfilled High-alloyed Electric Arc Furnace EAF slag; Slag neutralization potential; Slag recycling;

    Sammanfattning : The landfilling of slag obtained from the high alloyed Electric Arc Furnace (EAF) steel making process, constitutes an environmental treat for society as well as an economical problem for the companies producing it, due to the costs related to waste management practices. Conventional methods of slag recycling are abundantly used among the steelmaking business, but due to their particular physical properties, high- alloyed EAF slags cannot be properly valorized.

  4. 3. Inhibition of phosphorus release from sediments of Lake Erhai through argon oxygen decarburisation slag (AOD) and electric arc furnace slag (EAF) capping.

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Linda Lindholm; [2016]
    Nyckelord :;

    Sammanfattning : The effects of eutrophication in lakes and the open seas has been largely the result of phosphorus (P) that accumulate in the sediment. Eutrophication occurs mainly in the waters in densely populated coastal areas and agricultural dominated areas and occurs when an excess of nutrients reach the soil and water. LÄS MER

  5. 4. Environmental exposure assessment of metals from reclaimed land in Halmstad harbour : Sweden  Part of an environmental risk assessment

    Magister-uppsats, Högskolan i Halmstad/Miljövetenskap

    Författare :Karin Assarsson; [2015]
    Nyckelord :land fill; EAF slag; partitioning coefficient; environmental load; exposure assessment;

    Sammanfattning : The harbour land fill in Halmstad has been described in the news as one of the most polluted areas in Halland County based on the a survey from the Swedish environmental protection agency. In order to identify the extent and severity of the situation several environmental investigations have been performed in this area. LÄS MER

  7. 5. MAS-sten som ett möjligt material för att minska föroreningarna från deponin i Karlslund : Undersökning av nya tillämpningsområden för slagg från stålindustrin

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för geovetenskaper

    Författare :Birgitta Bodén; [2013]
    Nyckelord :slag; EAF; AOD; reactive filters; leachate; sorption; slagg; EAF; AOD; reaktiva filter; lakvatten; sorption;

    Sammanfattning : Till följd av den hårda utbyggnaden av vårt samhälle åtgår en stor mängd naturresurser. Samtidigt som samhället utveckas sätts allt högre krav på att det ska hushållas med naturresurser, inte minst genom införandet av miljömålet en ”God bebyggd miljö”. LÄS MER
