  1. 6. Excess heat utilisation in oil refineries - CCS and algae-based biofuels

    Författare :Viktor Andersson; 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; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; techno-economic; CO2 emissions; carbon dioxide; renewable diesel; post-combustion; algae biofuels; process integration; GHG emissions; oil refining industry; carbon capture and storage CCS ;

    Sammanfattning : The main objective of this thesis is to investigate two different concepts for CO2 mitigation, from a system perspective, in relation to the oil refining industry: CO2 capture and storage; and algae-based biofuels. For all these processes, process integration with an oil refinery is assumed. LÄS MER

  3. 7. 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. 8. Management of technology in the process industries:  Matching market and machine

    Författare :Peter Samuelsson; Pär Jönsson; Rob Boom; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process industries; manufacturing; innovation; configuration; strategizing; capability; configuration modelling; process industries; production system; physical modelling; AOD; converter geometry; injection; mixing times; electric arc furnace; EAF; post-combustion; high-impedance; network disturbances; operational results; Metallurgical process science; Metallurgisk processvetenskap;

    Sammanfattning : The process industries span multiple industrial sectors and constitute a substantial part of the entire manufacturing industry. Since companies belonging to this family of industries are often very asset intensive, their ability to respond to changes is often limited in the short term. LÄS MER

  5. 9. System studies of different CO2 mitigation options in the oil refining industry: Post-combustion CO2 capture and biomass gasification

    Författare :Daniella Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process integration; post-combustion CO2 capture. CO2 capture and storage CCS ; GHG emissions; oil refining industry; CO2 emissions; Fischer-Tropsch FT ; biomass gasification; energy market scenarios;

    Sammanfattning : To reach the objective endorsed by the EU Council for reducing EU greenhouse gas (GHG) emissions by 80-90% compared to 1990 levels by 2050, extensive cuts are necessary in all sectors. The oil refining sector is a major energy user and thus a major GHG emitter. LÄS MER

  7. 10. Environmental, health and safety assessment of phase-change solvents for post combustion CO2 capture

    Författare :Gulnara Shavalieva; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-change solvents; carbon capture; CAMD; LCA; EHS;

    Sammanfattning : A novel class of solvents exhibiting liquid-liquid phase separation upon reaction with CO2 and/or change in temperature, promises significant reduction of energy requirement of the post combustion capture by chemical absorption. However, proceeding to a large-scale application of novel materials requires holistic evaluation of the aspects related to human health, safety, and environmental impacts currently missing for phase-change solvent alternatives.
