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...
Probing Deformable Oil-Water Interfaces by Atomic Force Microscopy and Cascade Partial Coalescence MeasurementsDownload
Phase separation of stable oil-in-water and water-in-oil emulsions poses major challenges for a variety of industries, including the petroleum industry. The stability and destabilizing of petroleum emulsions highly depend on interfacial properties such as surface/interfacial charges, interfacial...
Understanding mineralogy and surface properties of fine solids is vital in oil sands processing and tailings management. Fine solids in oil sands are often contaminated by tightly bound organic matter (OM) originally or during hydrocarbon removal, thereby increasing surface hydrophobicity and...
A fundamental study of bubble-particle interactions through zeta-potential distribution analysisDownload
Understanding the mechanism of bubble-particle interactions plays a critical role in advancing flotation technology. In this study, submicron size bubbles with an average diameter less than 1 μm and a life time of at least several hours were generated using a novel hydrodynamic cavitation method....
Many tailings treatment technologies rely on the use of water-soluble polyacrylamides (PAM) to flocculate fine solids. However, PAM-induced flocs are often loosely-structured and retain significant volume of water due to the hydrophilicity of PAM and fine clays in oil sands fine tailings....
To better understand bitumen conditioning stage in oil sands extraction process a flow cell was designed to study bitumen liberation directly from sand grains, using real oil sand ore. A high-grade oil sand ore was subjected to various water temperatures and pH values to examine the bitumen...
A cationic thermal sensitive polymer, polyN-isopropylacrylamide-co-N-[3-(Dimethylamino)propyl]methacrylamide (CP) of different molar ratios, known as CP05 and CP10 was synthesized in-house. By doping aluminum hydroxide (Al(OH)3) colloids into CP during the polymerization process, a novel hybrid...
Study of Thin Liquid Film Drainage and Interaction Forces in Organic Solvent for Liquid/Solid and Liquid/Liquid Interactions Using Dynamic Force Apparatus (DFA)Download
Properties of thin liquid films between two approaching droplets or between a droplet and a solid surface are critical for emulsion stability and for mineral flotation. If the thin liquid film is stable, no coalescence occurs, while an unstable film will lead to rupture and coalescence or the...
A Surface Forces Apparatus (SFA) was used in this study to investigate the fundamental surface forces in oil sand processing research. Asphaltene coated surfaces were chosen as the research topic due to the critical role of asphaltenes in oil sands processing, from bitumen extraction, froth...
Study of biodiesel-assisted ambient aqueous bitumen extraction (BA3BE) for hydrocarbon production from mineable oil sandsDownload
Surface mining followed by Clark’s hot water bitumen extraction (HWBE) process has been employed in the current mineable oil sands industry for massive bitumen production. This method is faced with numerous challenges such as high energy consumption, limited bitumen quality, production from...
