Spring 2010
Research was conducted into using supercritical fluid extraction (SFE) for removing hydrocarbons from drill cuttings slurries, which will be used in a pilot-scale continuous SFE system currently under development. A laboratory-scale batch SFE system employing supercritical carbon dioxide (CO2)...

The net exchange of carbon greenhouse gases with high Arctic terrestrial and aquatic ecosystems
DownloadSpring 2015
Accelerated climate warming of Canada’s sparsely vegetated high Arctic has resulted in rapid environmental changes including loss of glacial ice, permafrost thaw, decreased snow cover and changing plant communities. These responses are causing mostly unknown changes to the natural cycling of the...

Temperature sensitivity of N2O emissions from fertilized agricultural soils: Mathematical modeling in ecosys
Download2008
N2O emissions have been found to be highly sensitive to soil temperature (T-s) which may cause substantial rises in emissions with rises in Ts expected in most climate change scenarios. Mathematical models used to project changes in emissions during climate change should be able to simulate the...

Study of electrical conductivity response upon formation of ice and gas hydrates from salt solutions by a second generation high pressure electrical conductivity probe
Download2014-11-01
Sowa, Barbara, Zhang, Xuehua, Kozielski, Karen A., Dunstan, Dave E., Hartley, Patrick G., Maeda, Nobuo
We recently reported the development of a high pressure electrical conductivity probe (HP-ECP) for experimental studies of formation of gas hydrates from electrolytes. The onset of the formation of methane-propane mixed gas hydrate from salt solutions was marked by a temporary upward spike in the...

Fall 2011
Carbon dioxide (CO2) was shown as a promising alternative for oil sands tailings treatment with economical and environmental benefits. This thesis aims to understand the role of CO2 addition in settling and densification of oil sands tailings. In this study, CO2 was pressurized into two...
