Fall 2014
The formation of stable water-in-oil emulsions during bitumen extraction poses problems for water separation from diluted bitumen, which leads to equipment corrosion and catalyst fouling in downstream operations. Demulsifiers are used to break the stable emulsions and assist the separation of...

Oil Upgrading by Molecular Rearrangement and Cracking: A Study Using Model Compounds and Natural Chabazite
DownloadFall 2015
As demand for fuel increases, new technologies that can convert heavy oil and bitumen into light fuels are needed. Natural zeolites have been proven to catalyze reactions that decrease molecular weight, density, nitrogen, and metals content as well as vacuum residue content when mixed with raw...

Analysis of goldfish innate immunity following exposure to oil sands process affected water
DownloadFall 2013
The acute and sub chronic effects of oil sands process affected water (OSPW) and its toxic component, naphthenic acids (NAs) were examined. I exposed goldfish for one (acute), or 12 (sub chronic) weeks and examined immune gene expression, macrophage function, the ability of exposed fish to...

Turbidity Mitigation in an Oil Sands End Pit Lake through pH Reduction and Fresh Water Addition
DownloadFall 2016
The remediation of oil sands wastes such as fluid fine tailings (FFT) and oil sands process-affected water (OSPW) are of increasing concern in the oil sands industry. End pit lakes are one remediation option currently being researched at commercial scale in Base Mine Lake (BML) operated by...

Biological Treatment of Naphthenic Acids and Other Organic Compounds in Oil Sands Process-Affected Waters
DownloadFall 2014
The Alberta oil sands contain one of the world’s largest reserves of oil - over 169 billion barrels of bitumen are economically recoverable with current extraction technologies. Surface mining, whereby the ore is extricated from the earth and bitumen is obtained via a hot water extraction...

Life Cycle Assessment of Transportation Fuels from Canada’s Oil Sands through Development of Theoretical Engineering Models
DownloadFall 2014
Oil sands in Canada are significant in fulfilling the current and the future energy demands of North America. The development of these resources, besides the increased awareness in global carbon management, has given way to various policy regulations such as the Low Carbon Fuel Standard (LCFS)...

Applications of Remote Hyperspectral Sensing in the Characterization of Alberta's Oil Sands Tailings
DownloadSpring 2016
The bitumen production from oil sands surface-mining operations produces large volumes of mineral wastes called tailings. Characterization of the oil sands tailings is of importance to monitor their state for trafficability and reclamation issues, to assess the tailings operation performance, and...

The impact of various ozone pretreatment doses on the performance of endogenous microbial communities for the remediation of oils sands process-affected water
DownloadFall 2015
In this study, the effects of different ozone pretreatment doses on the performance of endogenous microbial populations in degrading naphthenic acids (Nash and Traver) for the treatment of oil sands process-affected water (OSPW) were evaluated. The results showed that ozonation enhanced the...

Spring 2010
Molecular dynamics simulation and density functional theory were applied to calculate heats of immersion (ΔHimm) of n-heptane, toluene, pyridine and water on two model sand surfaces and two model clay surfaces. Our results indicated that water showed the highest ΔHimm for the model clay surfaces...

Productivity and carbon accumulation potential of transferred biofilms in reclaimed oil sands-affected wetlands
DownloadSpring 2011
Biofilms are significant contributors to primary production, nutrient cycling, bio-stabilization and the food web of wetland ecosystems. Photoautotrophic biomass (PB) and primary production (PP) were determined for biofilms exposed to various treatments and materials in wetlands near Fort...
