  1. 1. Upscaling and Evaluation of Absorption Based Systems for Co-removal of NOx and SOx from Flue Gases

    Författare :Jakob Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; absorption; gas-phase oxidation; scale-up; Emissions control; SOx; NOx; ClO2;

    Sammanfattning : As long as combustion remains a vital part of the energy system, the removal of nitrogen oxides (NOx) will be a challenge that will need to be addressed. In addition, emissions of sulfur oxides (SOx) will be a problem as long as fuels such as coal and oil are used, as is envisaged in every road map suggested by the Intergovernmental Panel on Climate Change (IPPC).

  2. 2. Decarbonization in Carbon-Intensive Industries - An Assessment Framework for Enhanced Early-Stage Identification of Optimal Decarbonization Pathways

    Författare :Tharun Roshan Kumar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon-intensive industries; Industrial decarbonization; Process integration; Cost estimation; CO2 Capture; Exergy and Pinch analyses; Process modeling;

    Sammanfattning : Carbon-intensive industries currently account for a quarter of global annual CO2 emissions. Achieving mandated climate targets necessitates the rapid implementation of decarbonization technologies in these industries. Such deployments typically involve substantial upfront investments amidst technical, economic, and policy uncertainties. LÄS MER

  3. 3. Technical and Economic Conditions for Efficient Implementation of CO2 Capture - process design and operational strategies for power generation and process industries

    Författare :Stefanìa Òsk Gardarsdòttir; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Post-combustion; CCS; chemical absorption; dynamic modeling; industrial sources; CO2 capture and storage; variable electricity generation;

    Sammanfattning : This thesis investigates the operational parameters of fossil-based power generation and industrial processes in future energy systems that have stringent constraints on CO2 emissions, and, consequently, large shares of renewable energy. CO2 capture and storage, which is the focus of this work, is required for power and industrial processes that emit CO2. LÄS MER

  4. 4. Hydrogen Production by Integration of Fluidized Bed Heat Exchanger in Steam Reforming of Natural Gas

    Författare :Viktor Stenberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BECCS; Steam reforming; CCS; Hydrogen; fluidized bed heat exchanger; Oxygen carrier aided combustion; chemical-looping combustion;

    Sammanfattning : The possibility to integrate fluidized beds as heat sources for steam reforming in hydrogen production plants is examined in this work. Sites with large-scale production and consumption of hydrogen such as refineries are considered as especially interesting. LÄS MER

  5. 5. Oxy-Fuel Combustion Combined Cycles for Carbon Capture

    Författare :Egill Maron Thorbergsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conceptual compressor design; oxy-fuel combustion combined cycles; Graz cycle; Carbon capture and storage; Semi-closed Oxy-fuel Combustion Combined Cycle;

    Sammanfattning : A short and medium term method to decrease carbon dioxide emissions is carbon capture and storage. This method captures carbon dioxide from point sources of emissions and then stores the carbon dioxide in geological formations. LÄS MER
