6. 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
7. Conditions for Industrial Symbiosis surrounding a hydrogen based steel industry
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : There is an ongoing transition to a more sustainable industry with lower climate impact. As part of this transition, the steel industry is expected to move from the conventional process for producing iron and steel using Blast Furnace (BF) and Basic Oxygen Furnace (BOF) processes, consuming large amounts of fossil fuels.

8. 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)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
9. 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/MaterialvetenskapSammanfattning : 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
10. Electrified Reforming of Biogas to Hydrogen for Industrial Furnaces with Negative Carbon Emissions: A Feasibility Study
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : 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.
