Spring 2017
Dewatering of the oil sands mature fine tailings (MFT) is studied through pressure filtration following treatment by dual polymer flocculants. Polymer pairs consisting of anionic polyacrylamide (A3335) and cationic polyDADMAC (Alcomer 7115), and A3335 and non-ionic polyethylene oxide (PEO) are...

There is a growing need to decrease the viscosity of bitumen using minimal diluent addition to reduce the cost of transportation. However, due to the inherently free radical rich nature of bitumen, even on exposure to low autoxidative conditions adverse effects on the viscosity and hardening of...

Fall 2018
The production of a tailings waste stream is ubiquitous to mining and mineral processing operations, especially in Alberta’s oil sands industry. Due to the presence of colloidal clays such as kaolinite, which do not naturally sediment in suspension, water recycling and land reclamation remain...

Remediation of bitumen-contaminated sand grains: development of a protocol for washing performance evaluation
DownloadSpring 2010
In the development of a non-aqueous bitumen extraction process, a major obstacle is solvent loss due to hydrocarbon attachment to the reject sand grains. A proposed solution to this problem is to wash (i.e. remediate) the oil-contaminated sand grains with water and surfactants. This research is...

Rheological behavior and nano-microstructure of complex fluids: Biomedical and Bitumen-Heavy oil applications
DownloadFall 2010
The main objective of this research was to exploit the interrelations between the rheological behavior and nano-microstructure of complex fluids in solving two state-of-the-art problems, one in the field of biomedical engineering: controlling the amount and characteristics of bioaerosol droplets...

The rheology of asphalt binders is an important factor in the design and construction of roads. As polymer modification is now often required to meet performance demands, the rheological behaviour of the binders has become increasingly complex. Within the past decade, a new method to evaluate...

Rheology of Bitumen at the Onset of Asphaltene Aggregation and its Effects on the Stability of Water-in-Oil Emulsion
DownloadFall 2015
Asphaltenes are the heaviest fraction of bitumen. Asphaltenes not only play an important role in the high viscosity of bitumen but also in the water-in-oil (W/O) emulsion stability. Nevertheless, their exact function in the stability mechanism of W/O emulsion still remains unresolved. It is...

Spring 2016
Effect of rotation on dynamcis of flow in microchannels is studied. In the frist study, an analytical solution is developed for the unsteady flow of fluid through a parallel rotating plate microchannel, under the influence of electrokinetic force using the Debye–Hückel (DH) approximation....

Sequence Stratigraphy, Porosity, and Primary Producers of the Middle to Late Devonian Canol Formation, Northwest Territories, Canada
DownloadFall 2022
The Devonian Canol Formation of the Northwest Territories (NWT) is an organic-rich mudstone interval deposited in a tropical marine setting along the west coast of Ancestral North America. This unit preserves a record of local marine conditions in the Middle to Late Devonian, a time characterized...

The current study investigates the effect of shear thinning rheology characteristics of high viscosity non-Newtonian biopolymers on the flow regime characterizations in Taylor Couette flow. The rheology measurements were carried out to investigate the viscoelastic properties of the biopolymers...
