  1. 1. Uranium nitride synthesis by gas/gas reaction of UF6 and NH3

    University essay from KTH/Fysik

    Author : Serena Ambrosino; [2024]
    Keywords : Uranium nitride; synthesis; ammonolysis; uranium hexafluoride; uranium tetrafluoride; ammonia; X-ray diffraction; microscopy; Urannitrid; syntes; ammonolys; uranhexafluorid; urantetrafluorid; ammoniak; röntgendiffraktion; mikroskopi;

    Abstract : This thesis project aims to develop an innovative technique for the production of high-purity uranium nitride (UN) through the ammonolysis of fluorides. The desired objective is to perform a controlled gas/gas reaction between uranium hexafluoride (UF6) and ammonia (NH3) at 800°C. READ MORE

  3. 2. Biobased iron pellet production : Assessment of the availability and sustainability of biomass as fuel for iron ore pellet production in LKAB

    University essay from Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)

    Author : Magnus Kemi; [2023]
    Keywords : bio-energy; biomass; coal; greenhouse gas emissions; industrial residues; LCA; LKAB; logging residues; iron ore; pellets; sinters; willow; sustainability;

    Abstract : 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. READ MORE

  4. 3. Evaluation of five hardwood species from Zambia to produce fuel pellets for cooking purposes : Study with a single pellet press including pellet production, post production testing and X-ray examinations

    University essay from Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

    Author : Annika Silvennoinen; [2023]
    Keywords : Pelletizing; Pellet Production; Wood Species; X-Ray examinations; Pelletisering; Pelletstillverkning; Träslag; Röntgenundersökningar;

    Abstract : 81% of the population in sub-Saharan Africa relies on charcoal and firewood to cover their energy needs for cooking. In Africa charcoal is usually produced by burning tree in a traditional kilns and then the food is cooked with a carbon-fired stoves indoors. READ MORE

  5. 4. Evaluation of The Viral Reduction Potential using Ultrafiltration Membranes in the Drinking Water Treatment Process at Norrvatten

    University essay from KTH/Industriell bioteknologi

    Author : Emma Eriksson; [2023]
    Keywords : Microbiological barrier; Ultrafiltration; NanoCeram filter; Drinking Water; Raw Water; Mikrobiologisk barriär; Ultrafiltering; NanoCeram filter; Dricksvatten; Råvatten;

    Abstract : En pilotanläggning för ultrafiltering testas nu i Norrvattens reningsprocess för att undersöka ifall den kan användas som en tredje mikrobiologisk barriär i reningsprocessen. Målet med detta projekt är att testa membranets kapacitet att filtrera bort viruspartiklar men även membranet generella reduktionsförmåga för andra mikrobiologiska och kemiska kontamineringar.

  6. 5. Optimal process design with simulation-based optimization

    University essay from KTH/Matematik (Avd.)

    Author : Giulia Grasso; [2023]
    Keywords : Optimization; Multi-Objective; Simulation-based; Optimering; flermålsoptimering; simuleringsbaserad;

    Abstract : 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. READ MORE
