A Study on the Effect of Temperature and Pressure on the Removal of Cyclohexane from Non-Aqueous Extraction Gangue
DownloadSpring 2015
Solvent based extraction has the potential to supplant the current hot water based extraction process as the industry standard method for recovering bitumen from mined oil sand. It has the potential for higher bitumen recovery that is less sensitive to the grade of oil sand ore being processed....

Spring 2015
The minable oil sands extraction process can be understood on a scale of a single oil sand grain. When the oil sand ore is mixed with warm water, each sand granule is initially covered with bitumen film which ruptures under the composite effect of shear and interfacial forces, while water...

Colloid Science of Sand Remediation: A Study Motivated by the Non-Aqueous Extraction of Bitumen from Oil Sands
DownloadFall 2014
The current water-based method of bitumen extraction requires withdrawal of fresh water from the Athabasca River — a practice which leads to the continual buildup of tailings ponds and other environmental concerns. As Alberta’s bitumen production is expected to more than double by 2020, there is...

Removal of a drop from its substrate may be gradually (e.g. evaporation) or all at once (e.g. shedding). In this thesis, drop adhesion force as a base for understanding the all at once removal of a drop from its substrate, and drop evaporation in room temperature as one of the gradual removal...

Dynamics of spontaneous initial spreading and spreading of a hydrodynamically driven droplet under the influence of surrounding pressure
DownloadFall 2021
We investigate experimentally the early time dynamics of spontaneous spreading of silicone oils with various viscosities at elevated surrounding pressures. The surrounding medium pressure is increased in a monotone fashion starting from atmospheric pressure to a maximum value of 30 megapascal...

Effect of Biochar on Soil Microbial Communities, Nutrient Availability, and Greenhouse Gases in Short Rotation Coppice Systems of Central Alberta
DownloadFall 2015
Short rotation coppice (SRC) systems using willow (Salix spp.) grown on marginal soil, amended with biochar may represent a promising source of renewable green energy for rural communities of Alberta. The Ohaton Wood Energy project, an agroforestry site located in Camrose County, is one of...

Effect of Temperature, Phase Change, and Chemical Additive on Interfacial Properties and Performance of Steam Applications
DownloadFall 2019
When considering the wettability state during steam applications, we find that most issues remain unanswered. Removal of polar groups from the rock surface with increasing temperature improves water wettability; however, other factors, including phase change, play a reverse role. In other words,...

Spring 2015
Previous studies on the extraction of liquid products from coals have focused mainly on increasing the yield, with very little emphasis on the quality of the liquid products. The main goal of this study is to achieve a balance between the yield and quality of the coal derived liquids. The first...

Fabrication and Characterization of Photolithographically Patterned Rough Surfaces Demonstrating Extreme Contact Angle Behavior
DownloadFall 2014
This thesis features experimental work done to fabricate and characterize silicon surfaces patterned using photolithographic techniques, both standard and novel, to produce a variety of surfaces with roughness of controlled geometric properties. In specific, one set of the surfaces fabricated...

Soil stockpiles are used around the world to reclaim sites affected by industrial activities. Oil sands surface mining and in situ extraction activities in Alberta, Canada, have directly impacted more than 900 km2 of land, with more development expected in the future. Soil stockpiles will be...
