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...

Spring 2015
This thesis presents a thorough examination of the corrosion and fouling behaviour of crude oil at refining conditions on industrially applicable heat transfer surfaces. The depletion of light sweet crude oil reserves means that the processing of ever heavier and more sour crude oils is...

Spring 2016
The tendency of asphaltenes to aggregate in crude oil is observed at SATP and is enhanced at elevated temperatures. At these conditions, asphaltenes aggregation is a problem as it will ultimately lead to mesophase formation, a precursor of coke, known for causing plugging and fouling of...

Development of a yogurt powder formulation that can produce a recombined product with physicochemical and rheological properties similar to those found in commercial Greek-style yogurts
DownloadSpring 2013
Greek yogurt (GY) is known as strained or concentrated form with total solids (TS) of at least 22.0% and 14.3% for full and fat free, respectively. TS are increased, in traditional GY, by “draining off” whey after milk fermentation by typical mixture of yogurt bacteria. Current studies were...

Development of Solvent Selection Criteria Based on Diffusion Rate, Mixing Quality, and Solvent Retrieval for Optimal Heavy-Oil and Bitumen Recovery at Different Temperatures
DownloadFall 2015
Heavy-oil and bitumen recovery requires high recovery factors to offset the extreme high cost of the process. Attention has been given to solvent injection for this purpose and it has been observed that high recoveries are achievable when combined with steam injection. Heavier (“liquid”) solvents...

Spring 2013
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...

Dynamic Demulsification Mechanism of Asphaltene-Stabilized Water-in-Oil Emulsions by Ethylcellulose
DownloadFall 2015
In previous studies, nontoxic and biodegradable ethylcellulose (EC) was shown to be capable of breaking water-in-diluted bitumen emulsions. Nevertheless, the demulsification mechanism of EC has not been correlated to its effect on the physical properties of stabilizing interfacial asphaltene...

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 Cellulose Nanocrystal Particles on Rheology, Transport and Mechanical Properties of Oil Well Cement Systems
DownloadSpring 2018
The increase in oil consumption during the past few decades, coupled with oil/gas extraction from shale in the recent years has increased drilling and cementing demands. Well cementing operation is one of the most crucial and important steps in any well completion. However, since it takes place...

Spring 2016
Thickened tailings technology is implemented in some oil sands operations in order to recycle warm process water, thereby reducing net water draw, and to reduce the size of tailings impoundment areas. The rheology of thickened tailings is complex and time-dependent, and the underlying mechanism...
