  1. 1. The Effects of ETS & CBAM on Cost Differences in the European Steel Industry : A Case Study on Swedish and German Long Engineering Steel Manufacturers

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Tim Fahlstedt; Oliver Håkansson; [2022]
    Nyckelord :ETS; CBAM; Carbon Leakage; Steel; EAF; Scrap; Cost Predictions.; ETS; CBAM; Koldioxidläckage; Stål; Ljusbågsugn; Skrot; Kostnadsanalys.;

    Sammanfattning : To combat anthropogenic climate change and comply with the Paris Agreement, the EU has previously introduced its Emissions Trading System (ETS) and has now also proposed a Carbon Border Adjustment Mechanism (CBAM). While these tools may reduce emissions within the EU, and in some cases, even in other countries, they can also affect European industries in unpredictable and sometimes negative ways. LÄS MER

  2. 2. Supervised Machine Learning Modeling in Secondary Metallurgy : Predicting the Liquid Steel Temperature After the Vacuum Treatment Step of the Vacuum Tank Degasser

    Master-uppsats, KTH/Materialvetenskap

    Författare :Roberto Vita; [2022]
    Nyckelord :Industy 4.0; Machine Learning; Statistical Modeling; Temperature Prediction; Vacuum Tank Degasser; Vacuum Treatment Step.; Industri 4.0; Maskininlärning; Statistisk modellering; Temperaturförutsägelse; Vakuumbehandlingssteg; Vakuumtankavgasare;

    Sammanfattning : In recent years the steelmaking industry has been subjected to continuous attempts to improve its production route. The main goals has been to increase the competitiveness and to reduce the environmental impact. The development of predictive models has therefore been of crucial importance in order to achieve such optimization. LÄS MER

  3. 3. Electrified Reforming of Biogas to Hydrogen for Industrial Furnaces with Negative Carbon Emissions: A Feasibility Study

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Moa Bertling; Agnes Milstig; [2022]
    Nyckelord :;

    Sammanfattning : The steel industry emits large amounts of carbon dioxide, the main emissions are produced inthe process of heating up steel in industrial furnaces of electric arc furnaces (EAF). The purposeof this project was to propose and evaluate a process of reforming biogas to hydrogen to use asfuel for industrial furnaces and result in carbon neutral or carbon negative emissions.

  4. 4. 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

  5. 5. 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
