Fall 2020
In the traditional water-based extraction process, sodium hydroxide (NaOH) is a commonly used chemical aid to improve bitumen recovery from oil sands. Recently, sodium citrate (Na3Cit) was applied as a secondary process aid together with NaOH by Syncrude Canada Ltd. in the water-based extraction...

Fundamental Understanding of the Interactions between Elemental Selenium and Hydrophilic/Hydrophobic Particles in Wastewater
DownloadFall 2015
In this study, interactions between elemental selenium particles and different surfaces (i.e. Fe(OH)3, silica, octadecyltrichlorosilane (OTS) modified silica and selenium film coated gold) are investigated to understand the behavior of elemental selenium particles in wastewater treatment process....

Fundamental Understanding on the Inception of Hydrodynamic Cavitation and its Generated Microbubbles in Fine Particle Flotation
DownloadFall 2022
Hydrodynamic cavitation is a frequently occurring phenomenon with positive and negative implications. Research has been mostly conducted to avoid cavitation in the last century because it is the major cause of corrosion in the marine industry. With the progress of science and technology,...

Spring 2011
Bitumen recovery by the water-based extraction process produces waste streams known as tailings. When discharged into the tailing ponds, the coarse solids in the tailings stream settle out quickly, while the fine solids accumulate over years of settling to a solids content of 30-35% by weight....

Hydrothermal Treatment of Low Rank Coal for Making High Solid Loading and Stable Coal Water Slurries
DownloadFall 2014
The objective of this research is to understand the effect of hydrothermal dewatering (HTD) on surface properties, stability and rheological behavior of lignite water slurry (LWS). The surface forces between coal particles are found to be attractive after HTD, which is proven by contact angle and...

Fall 2010
The purpose of this study is to investigate the impact of solvent addition to bitumen froth on the wettability of froth solids. The wettability of solids determines the transportation/partitioning of the solids between phases, which in turn affects the solids and water rejection in a Clark hot...

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...

Fall 2015
In this study, the flotation behaviors of chalcopyrite and pyrite single and mixed minerals in Milli-Q water, NaCl solution, and sea water were investigated. The performance of different collectors was evaluated. Collectorless flotation was also studied under potentiostatic control to explore the...

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...

Fall 2016
Asphaltenes are the heaviest component in crude oil and bitumen. The molecular interactions and interfacial behaviours of asphaltenes are closely related to many challenging issues in oil production, which are believed to play an important role in stabilizing water-in-oil (W/O) and oil-in-water...
