Spring 2013
As one of the most critical steps to recover valuable particles from a slurry using flotation, knowledge of the drainage of the thin liquid film between an air bubble and a solid surface is required. The main focus of this thesis is to develop and use an integrated thin film drainage appratus...

Spring 2014
Environmental concerns about water-based extraction necessitate the development of an alternative non-aqueous extraction method. One of the challenges that any non-aqueous extraction process is encountered is the elimination of suspended fine solids from solvent-diluted bitumen. This study...

Characterization of Athabasca asphaltenes separated physically and chemically using small-angle X-ray scattering
DownloadFall 2010
Athabasca asphaltenes were characterized using small-angle X-ray scattering (SAXS) with synchrotron radiation. Two methods were used to separate asphaltenes from Athabasca bitumen. Conventional chemical separation by precipitation with n-pentane, and physical separation realized by passing...

Fall 2010
A study was conducted to evaluate the properties and processes influencing the rate and magnitude of volume decrease and strength gain for oil sand fine tailings resulting from a change in bitumen extraction process (caustic versus non-caustic) and the effect of adding a coagulant to caustic fine...

Effect of Near-Wall Turbulence on Selective Removal of Particles from Sand Beds Deposited in Pipelines
DownloadFall 2012
A large-scale experimental facility was designed, constructed, and operated to study multiphase flow of solid-liquid mixtures (i.e., slurry flow) in horizontal pipelines. Trains of discrete lenticular deposits (LDs) and continuous beds were identified and studied in detail, representing two...

Spring 2021
Hot water extraction technique has been applied to extract bitumen from oil sands for decades. With the challenge of low oil prices, achieving higher recovery and efficient production becomes more urgent. In recent years, the overall recovery and froth quality have been improved significantly...

Experimental Investigation of the Effect of NaCl Additive on the Formation and Evolution of Particles in a Diffusion Flame
DownloadSpring 2017
Formation and evolution of nano-particles in a laminar co-flow methane diffusion flame were investigated under two conditions: a pure methane flame and a methane flame doped with NaCl particles. Samples of nano-particles from different heights above the burner were extracted by a probe sampling...

Modification of pulse starch properties by nanoparticulation and phosphorylation techniques
DownloadFall 2021
The global demand for plant-based protein is fast growing. This has resulted in significant expansion of pulse grain fractionation and value-added processing operations that primarily focus on protein refining. Pulse starches, as the major by-product of those operations, remain underutilized...

Role of Sodium Hydroxide in Bitumen Extraction: Production of Natural Surfactants and Slime Coating
DownloadSpring 2015
Alkaline environment by addition of NaOH in bitumen extraction process often shows a positive effect on bitumen recovery from Athabasca oil sands by mining-extraction method. NaOH ionizes organic acids in the bitumen to produce surfactants. These species are essential for bitumen liberation....

Techno-economic assessment of solvent-based bitumen extraction technologies including in-situ electromagnetic heating
DownloadFall 2021
The oil sands are a vast fossil fuel resource that supports the worldwide energy supply. The bitumen found in fossil deposits is too viscous to flow under reservoir conditions. For this reason, steam-based processes such as steam-assisted gravity drainage (SAGD) are used to increase the reservoir...
