  1. 1. Reducing Carbon Dioxide Emissions from the EU Power and Industry Sectors - An assessment of key technologies and measures

    Författare :Johan Rootzén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industry; carbon dioxide; cement; European Union; technologies; emission reductions; CCS; power; steel; CO2< sub>; refining; mitigation;

    Sammanfattning : In February 2011, the European Council reconfirmed the goal of reducing EU greenhouse gas emissions by at least 80% by 2050, as compared to the levels in 1990. The power and industrial sectors currently account for almost half of the total GHG emissions in the EU. LÄS MER

  3. 2. Process integration in the steel industry : possibilities to analyse energy use and environmental impacts for an integrated steel mill

    Författare :Mikael Larsson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : There is a growing awareness of serious problems associated with the use of energy. These problems include local and global environmental degradation associated with energy use and depletion of resources. LÄS MER

  4. 3. Environmental preferences among steel stakeholders

    Författare :Stina Alriksson; Marianne Henningsson; Carl-Erik Grip; Anders Roos; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; conjoint analysis; environmental communication; focus group; light weighting; PLS; preferences; Q-methodology; risk perception; steel; stakeholders; Miljövetenskap; Environmental Science;

    Sammanfattning : Emissions of carbon dioxide, dioxins, nitrogen oxides and particulate matter as well as use of non-renewable resources and energy are some important sustainability challenges for the Swedish steel industry. Much effort has been made, mainly by technical solutions, which to a high degree have decreased the emissions during the last 30 years. LÄS MER

  5. 4. The low-carbon steel industry - Interactions between the hydrogen direct reduction of steel and the electricity system

    Författare :Alla Toktarova; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable Energy; Energy systems modelling; Hydrogen-direct reduction; Steel industry; Electrification;

    Sammanfattning : The European steel industry must achieve deep reductions in CO2 emissions to meet the targets set out in the Paris Agreement. Options for reducing CO2 emissions include electrification, carbon capture and storage (CCS) and the use of biomass. LÄS MER

  7. 5. Degradation Mechanisms of Heat Resistant Steel at Elevated Temperatures : In an Iron Ore Pelletizing Industry

    Författare :Erik A. A. Nilsson; Marta-Lena Antti; Ragnar Tegman; Jan-Erik Svensson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; Grate-Kiln; microstructure; corrosion; as-casted; thermal cycling; erosion; deposition; Engineering Materials; Materialteknik;

    Sammanfattning : This thesis focuses on the different degradation mechanisms of the stainless steel in a travelling grate in a Grate-Kiln iron ore pellet indurator. The travelling grate is a conveyor belt that transports green-body pellets to a rotary kiln while the pellets are being dried and pre-heated to a temperature of 900-1100 °C by recycled hot air.
