  2. 1. Residual Trapping in Geological Storage of CO2 : Determination from Field Experiments and Data Analysis Using Numerical Modeling

    Author : Saba Joodaki; Auli Niemi; Zhibing Yang; Jonathan Ennis-King; Uppsala universitet; []
    Keywords : Residual trapping; CO2 geological storage; Dissolution trapping; Field experiment; numerical modeling; Geovetenskap med inriktning mot miljöanalys; Earth Science with specialization in Environmental Analysis;

    Abstract : Geological storage of CO2 in deep saline aquifers is one of the methods to mitigate the release of this greenhouse gas into the atmosphere. The efficiency of this solution can be improved by better understanding of the relevant trapping processes, as well as by improving available injection techniques and developing tools for more accurate site characterization.

  4. 2. Residual and Solubility trapping during Geological CO2 storage : Numerical and Experimental studies

    Author : Maria Rasmusson; Fritjof Fagerlund; Auli Niemi; Jonathan Ennis-King; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; capillary trapping; CCS; convective flow; CO2; light transmission; SO2; well test; Hydrology; Hydrologi;

    Abstract : Geological storage of carbon dioxide (CO2) in deep saline aquifers mitigates atmospheric release of greenhouse gases. To estimate storage capacity and evaluate storage safety, knowledge of the trapping mechanisms that retain CO2 within geological formations, and the factors affecting these is fundamental. READ MORE

  5. 3. Acoustic Trapping in Biomedical Research

    Author : Björn Hammarström; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microfluidics; Ultrasound; Acoustic Trapping; Lab-on-a-Chip; Mass Spectrometry;

    Abstract : Herein a method that uses acoustically resonating glass capillaries and enables non-contact capture of micron-sized bioparticles, i.e. acoustic trapping, is described. A miniaturized ultrasonic transducer is used to locally actuate a cross-sectional resonance in the capillary. READ MORE

  6. 4. Modeling of geohydrological processes in geological CO2 storage – with focus on residual trapping

    Author : Kristina Rasmusson; Auli Niemi; Fritjof Fagerlund; Rainer Helmig; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; capillary trapping; CCS; characterization test; CO2; injection design; pore-network model; Hydrology; Hydrologi;

    Abstract : Geological storage of carbon dioxide (CO2) in deep saline aquifers is one approach to mitigate release from large point sources to the atmosphere. Understanding of in-situ processes providing trapping is important to the development of realistic models and the planning of future storage projects. READ MORE

  7. 5. Cold trapping and reinjection techniques for gas chromatography-mass spectrometry

    Author : Sven P. Jacobsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis describes the use of cold trapping and reinjection techniques in combination with gas chromatography-mass spectrometry. A summary of different cold trap/ reinjection systems is presented. READ MORE
