Understanding the Role of Caustic Addition: A Comparison of Sodium Hydroxide and Ammonium Hydroxide
DownloadSpring 2012
To understand the role of caustic addition and its effect on the bitumen extraction process, a novel flow cell and a Denver Cell extraction unit were utilized. This allowed for the comparison of sodium hydroxide and ammonium hydroxides effect on real oil sands ores. Several ores (A1, C-ore,...

Study of Thin Liquid Film Drainage and Interaction Forces in Organic Solvent for Liquid/Solid and Liquid/Liquid Interactions Using Dynamic Force Apparatus (DFA)
DownloadFall 2021
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...

Fall 2017
Rapid, efficient and economical water removal from fluid fine tailings represents a major challenge to many industries, including mineral processing, food processing, waste water treatment and oil sands extraction. In the absence of large-scale fine tailings processing facilities, there will be...

Fall 2014
Interactions of finely dispersed abrasive particles in chemical mechanical planarization (CMP) slurries play a vital role in determining the polishing performance. In this study, coupled influence of hydrodynamic and colloidal interactions on the attachment of nanosized ceria (CeO2) particles to...

Fall 2011
This project was initiated to study the H2S removal process from liquid sulfur and later extended to generic liquid degassing scenarios. Enersul HyspecTM Degassing Process was first field tested so that comparison could be made with new units to be engineered. Two new degassing units were...

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...

Spring 2017
The formation of stable water-in-oil emulsions during oil sands extraction process causes a number of operational issues, such as equipment corrosion, storage and transportation problems. One common method for emulsion breakup in industry is to use chemical demulsifiers. The chemical demulsifiers...

Spring 2010
Commercial Magnafloc 1011and in-house synthesized Al-PAM were used as flocculants for model tailings, laboratory extraction tailings and tailings from paraffin froth treatment unit. The polymers were tested for their flocculation ability in settling and filtration. For model tailings, both...

Fall 2014
Management of oil sands tailings from bitumen extraction operations remains a challenge for mineable oil sands producers. Promoting fine solids settling in tailings ponds is key to treating oil sands tailings. Present study explores two methods of tailings treatment – ATA process and polymer...

Interfacially Active Magnetic Nanoparticles for Efficient Oil/Water Separation from Oil-in-Water or Water-in-Oil Emulsions
DownloadSpring 2020
The emulsions, either oil-in-water (O/W) or water-in-oil (W/O) emulsions, are inevitably formed during the industrial production processes and the daily household activities. The O/W emulsions such as crude oil-in-water emulsions or oily wastewaters generated from the industrial fields, oil...
