1. Biobased iron pellet production : Assessment of the availability and sustainability of biomass as fuel for iron ore pellet production in LKAB
Master-uppsats, Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)Sammanfattning : Iron production accounts for substantial shares of global coal use and GHG emissions. LKAB is Europe’s largest iron company and Sweden’s fourth-largest emitter of GHGs. To reduce its emissions, LKAB might implement biomass in iron ore pelletisation. LÄS MER
2. Optimal process design with simulation-based optimization
Master-uppsats, KTH/Matematik (Avd.)Sammanfattning : Nowadays, it has become crucial to transform company production processes in order to reduce carbon emissions. Therefore, the company LKAB is working to make the production process of iron ore pellets fossil-free. In particular, this thesis project focuses on the pellet induration stage and addresses the mathematical optimization of the process. LÄS MER
3. The Kinetics of Water Removal From an Iron Ore Pellet Prior to Hydrogen Reduction
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : Humanity is facing one of the biggest challenges ever presented in fighting climate change. To counter global warming, industries and scientists across the world are shifting manufacturing towards fossil independence in order to decrease emissions. LÄS MER
4. Tillämpning av Partial Least Squares för analys och processövervakning av Hybrits reduktionsprocess
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälleSammanfattning : Hybrit development AB är ett bolag som strävar mot att kunna producera fossilfritt stål genom att reducera järnmalmspellets med hjälp av vätgas. Därför har Hybrit utfört experimentella kampanjer där genomförbarheten av att reducera järnmalmspellets med hjälp av vätgas undersökts och studerats. LÄS MER
5. Theoretical Considerations and Experimental Observations on Heat Transfer in Hydrogen Direct Reduced Iron
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Steel has played an indispensable role in shaping our contemporary world and will persist to play that role for the foreseeable future. However, the steel industry currently is responsible for 7% of the global CO2-emissions, primarily due to the conventional carbon-based reduction process of iron ore. LÄS MER
