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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Yuting Tan; KTH.; [2017]
    Keywords : 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;

    Abstract : 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. READ MORE

  2. 2. Thermodynamic Properties of CO2 Mixtures and Their Applications in Advanced Power Cycles with CO2 Capture Processes

    University dissertation from Stockholm : KTH

    Author : Hailong Li; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermodynamic property; vapour liquid equilibrium; density; equation of state; interaction parameter; CO2 mixtures; evaporative gas turbine; chemical absorption; oxy-fuel combustion; cost evaluation; CO2 capture and storage; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Abstract : The thermodynamic properties of CO2-mixtures are essential for the design and operation of CO2 Capture and Storage (CCS) systems. A better understanding of the thermodynamic properties of CO2 mixtures could provide a scientific basis to define a proper guideline of CO2 purity and impure components for the CCS processes according to technical, safety and environmental requirements.

    University dissertation from Örebro : Örebro universitet

    Author : Emma M. Johansson; Örebro universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; amino acids; 13C; carbon cycle; ectomycorrhiza; elevated CO2; exudation; DOC; LMWOA; metal stress; monosaccharides; oxalate; Pinus sylvestris; saprotrophic fungi; soil respiration; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi; Enviromental Science; Miljövetenskap;

    Abstract : The thesis concerns the behavior of root and ectomycorrhizal (ECM) exudates. In particular, the dynamics of soluble low molecular weight (LMW) organic compounds such as organic acids (LMWOAs), amino acids, monosaccharides, and dissolved organic carbon (DOC) have been studied.

  4. 4. Narrow-pore zeolites and zeolite-like adsorbents for CO2 separation

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Ocean Cheung; Stockholms universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CO2 separation; zeolites; phosphates; titanium silicates; ion exchange; flue gas CO2 capture; biogas upgrading; materialkemi; Materials Chemistry;

    Abstract : A range of porous solid adsorbents were synthesised and their ability to separate and capture carbon dioxide (CO2) from gas mixtures was examined. CO2 separation from flue gas – a type of exhaust gas from fossil fuel combustion that consists of CO2 mixed with mainly nitrogen and biogas (consists of CO2 mixed with mainly methane) were explicitly considered.

  5. 5. Microfluidics at High Pressures Understanding, Sensing, and Control

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Martin Andersson; Uppsala universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-pressure microfluidics; supercritical CO2; compressible flow; relative permittivity; integrated electrodes; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Abstract : This thesis explores understanding, sensing, and control in high-pressure microfluidics. The high-pressure regime allows fluids to be forced through narrow channels at substantial speed and creates conditions for fluids of high density and low viscosity—features desired in flow-based chemical analyses.
