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...

Acid-base properties of cyanobacterial surfaces II: Silica as a chemical stressor influencing cell surface reactivity
Download2008
Owttrim, G.W., Lalonde, S.V., Smith, D.S., Konhauser, K.O.
Bacteria grow in complex solutions where the adsorption of aqueous species and nucleation of mineral phases on the cell surface may interfere with membrane-dependent homeostatic functions. While previous investigations have provided evidence that bacteria may alter their surface chemical...

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...

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...

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...

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....

Study of non-equilibrium interactions between an air bubble and a hydrophilic/hydrophobic solid surface with the non-linearized Stokes-Reynolds-Young-Laplace model (NSRYL model)
DownloadFall 2014
The interaction between bubbles and solid surfaces is important to a broad range of industrial and biological processes. Various experimental techniques have been developed to measure the interactions of bubbles approaching solids in a liquid. In this thesis the consistency and accuracy of such...

Study of the Intervening Thin Liquid Film between Deformable Oil Drop/Bubble and a Solid Surface in Oil Production
DownloadSpring 2022
Interactions involving deformable bubbles/oil droplets play a critical role in many industrial applications. Understanding the dynamic thin film drainage process and interaction forces involving deformable bubbles/oil droplets and solid surfaces in the oil sands extraction process is of great...

During separation of emulsified water from oil, a viscous intermediate layer builds up between water and oil phases. This layer which is referred to as rag layer disrupts emulsion destabilization and water removal. The present research is intended to better understand the formation of a rag layer...

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...
