Fall 2021
The lower Athabasca River valley in northeastern Alberta, famous for oil sands mining, was also the site of one of North America largest Ice Age floods. During deglaciation, a large proglacial lake, Lake Agassiz, drained catastrophically through the Athabasca River valley. This catastrophic flood...

The Discharge Crucible Method: update on experimental design, measurements, and orifice wetting
Download2022-01-01
The physicochemical properties, viscosity, density, and surface tension, are critical properties of liquid metals and alloys. These properties are needed for thermodynamics, solidification modelling, and materials properties databases. The discharge crucible method (DC) developed in 2003 has been...

The role of functional properties of dietary fiber in the control of nutrient flow and intestinal health in pigs
DownloadFall 2010
Viscosity and fermentability are considered important properties of dietary fiber. Viscosity increases digesta viscosity and reduces digesta passage rate, nutrient digestion and absorption whereas fermentability increases fermentation into short chain fatty acids (SCFA). The objectives were to...

The Roles of Constituent Minerals and Residual Bitumen in the Filtration of Alberta Oil Sands Tailings
DownloadFall 2022
The dewatering of Alberta oil sands tailings is one of the most challenging problems faced by the oil sands industry. Despite significant efforts in the past several decades, the industry still lacks viable technologies that can quickly dewater and reclaim the oil sands tailings and eliminate...

Fall 2018
Canada has one of the largest oil reserves in the world, with around 3 trillion ultimate reserves in heavy oil. Even though, one of the major difficulties that Canadian Oil sands industry has faced over time is the transportation of bitumen due to its extremely high viscosity. Having this in...

Thermophysical Properties Measurement of Liquid Al and Al-Cu by the Discharge Crucible Method
DownloadFall 2020
The demand to develop Materials Genomics and Integrated Materials Computation requires the availability of high temperature property data of liquid metals. High temperature metallurgical processes, such as refining, casting, welding and additive manufacturing, can be optimized and operate more...

Ultrasonic Characterization of Bitumen with Pressure and Temperature: Implications for seismic monitoring of the Grosmont Formation
DownloadFall 2018
The vastly untapped carbonate Grosmont Formation in north-eastern Alberta may hold in excess of a couple of hundred billion barrels initial volume of bitumen in place. Bitumen, an ultra-heavy hydrocarbon oil, possesses a density comparable to water, but a dynamic shear viscosity million times...

Understanding stability of water-in-diluted bitumen emulsions by colloidal force measurements
DownloadSpring 2011
Removal of emulsified water is a challenge in oil sands and heavy oil processing. The flocculation and coagulation of emulsified water droplets depend on the interactions between the water droplets covered mainly by asphaltenes and oil-contaminated fine solids. To quantitatively evaluate the...

Understanding the Role of Caustic Addition: A Comparison of Sodium Hydroxide and Ammonium Hydroxide
DownloadSpring 2012
To understand the role of caustic addition and its effect on the bitumen extraction process, a novel flow cell and a Denver Cell extraction unit were utilized. This allowed for the comparison of sodium hydroxide and ammonium hydroxides effect on real oil sands ores. Several ores (A1, C-ore,...
