Beyond Viscosity—How Density, Vibration and Interfacial Tension Affect Solvent Aided Bitumen Production
DownloadFall 2016
Bitumen and heavy oil comprise a significant percentage of proven oil reserves globally. The environmental impacts of producing these resources with current technologies is a concern for environmentalists, oil producing companies, resource rich jurisdictions and society at large. Dilution of the...

Overly-stable froth in mineral flotation columns are sometimes a problem for separation operations. Greater quantities of fine particles in the input slurry can contribute to froth that is too stable and overruns the equipment capacity. Currently, the best ways to deal with this problem are to...

Canada has the largest known reserve of oil in the world in the form of oil sands: an estimated 1.7 to 2.5 trillion barrels of oil are deposited in combination of the sand, water and clay. The presented research is devoted to bubble-solid surface interaction, which is one of the critical areas...

Study of thin liquid film drainage in bubble-liquid-solid systems using integrated thin liquid film force apparatus (ITLFFA)
DownloadFall 2017
Interactions involving deformable surfaces reveal a number of distinct physicochemical characteristics that do not exist in interactions between rigid solid surfaces. The main focus of this thesis is to develop a unique fully custom-designed instrument, referred to as an integrated thin liquid...

Understanding Surface Forces and Interaction Mechanisms in Mineral Flotation by Atomic Force Microscopy
DownloadFall 2019
Bubble-particle interactions are ubiquitous and crucial to mineral fotation. The bubble-particle attachment process is mainly governed by three surface forces: van der Waals (vdW), electrical double-layer (EDL), and hydrophobic (HB) forces. Atomic Force Microscopy (AFM) has become the most...
