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

2. Residual and Solubility trapping during Geological CO2 storage : Numerical and Experimental studies
Sammanfattning : 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. LÄS MER
3. Acoustic Trapping in Biomedical Research
Sammanfattning : 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. LÄS MER
4. Modeling of geohydrological processes in geological CO2 storage – with focus on residual trapping
Sammanfattning : 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. LÄS MER
5. Cold trapping and reinjection techniques for gas chromatography-mass spectrometry
Sammanfattning : 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. LÄS MER
