  1. 1. Property Impacts on Heat Exchanger Design in CO2 Cryogenic Process of Carbon Capture and Storage

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Yuting Tan; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Literature review; CO2 conditioning; CO2 transport; CO2 storage; CO2 mixtures; CO2 cryogenic; heat exchanger; sizing design; property impact; viscosity; thermal conductivity; property model; Energiteknik; Energy Technology;

    Sammanfattning : Carbon capture and storage (CCS) is one of the most promising technologies which can significantly reduce CO2 emissions. A better understanding of thermo-physical properties of CO2 mixtures is required for the design and operation of different CCS processes. LÄS MER

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

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Daniella Johansson; [2013]
    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

  3. 3. Towards CO2 efficient centralised distribution

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Christofer Kohn; Linköpings universitet.; Linköpings universitet.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 emissions; Centralised distribution; Structural change; Shipper; Transport; Trade-off; Interrelationship; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This dissertation treats a topic that has received increasing attention as of late, namely that of the environment and in particular increasing levels of CO2 emissions caused by transport. The aim of the dissertation is to explain how a shipper, through various measures, can reduce transport-related CO2 emissions when centralising a distribution system and how this affects the provision of cost efficient customer service.

  4. 4. Traffic Emissions of Aerosols

    Detta är en avhandling från Stockholm : Department of Applied Environmental Science (ITM), Stockholm University

    Författare :Matthias Vogt; Stockholms universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Primary Aerosol Emissions; Carbon Dioxide Emissions; Traffic Aerosol; Urban Aerosol; Traffic Activity; Emission Factors; Eddy Covariance; Aerosol Flux; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap; tillämpad miljövetenskap; Applied Environmental Science;

    Sammanfattning : Non-exhaust traffic emissions are unregulated, yet the mass emission of non-exhaust particles may be larger than exhaust emissions. In addition, their emission factors (EF) are more uncertain than exhaust emissions. This thesis presents aerosol flux measurements in Stockholm using the eddy covariance method. LÄS MER
