Characterization of Clay Minerals in the Athabasca Oil Sands in Water Extraction and Nonaqueous Solvent Extraction Processes
DownloadFall 2011
Production of oil from the second largest oil deposit in the world, i.e., the Alberta oil sands containing approximately 13% of total proven oil reserves in the world (169.9 billion barrels), has been shown to be significantly influenced by clay minerals. Clay minerals in particular play a key...

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...

Fall 2017
The present research was conducted with the intent of evaluating the degradation of OCTG (Oil Country Tubular Goods) steel used in SAGD (Steam Assisted Gravity Drainage) applications, and developing a promising surface modification method and a novel composite coating using a technique that will...

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...

Spring 2014
Seven Ni-WC tubular wires utilized in this study were characterized by the nickel sheath area, powder composition, and overall initial carbide volume fraction of the wire prior to welding. The electrical resistivity of steel, stainless steel, and Ni-WC welding consumables were measured from...

Determination of biokinetic parameters of wastewater biofilms from oxygen concentration profiles
DownloadFall 2011
The process of scale-up and rational optimization of biofilm processes for effective wastewater treatment and reuse require better understanding of the biokinetic behavior of microorganisms in the biofilms. At present, no fast and accurate methods exist for determining kinetic parameters for...

Fall 2011
Microelectrodes can be used for profiling environmental biofilms. Currently there is no sulfate microelectrode available for studying sulfate reduction in biofilms. In this study, a sulfate microelectrode was fabricated and tested in measurement of environmental biofilms for the first time. The...

Spring 2020
Albertan oil sands ores are becoming more difficult to process efficiently as the clay content of the ore increases and the grade of the ore worsens. A key to improving the extraction of bitumen from low-grade oil sands, thereby increasing the longevity of this critical resource, is reducing the...

Efficacy of conventional and novel antimicrobial treatments on the inactivation of desiccated cells and biofilms of Salmonella
DownloadSpring 2024
Repeated isolation of Salmonella from the dry and wet environments of the food industry poses a significant concern to human health. It is crucial to understand the influence of the various environmental conditions on Salmonella’s survival. The overall objective of this research was to evaluate...
