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...

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...

A Molecular Dynamics Approach towards the Interfacial Properties of Sulfide- and Clay-Minerals
DownloadSpring 2019
Interfacial properties have a regulatory role in processes which involve the coexistence of different phases. Although such macro-scale properties are determined by the intrinsic nature of the interface-sharing phases, it is possible to alter them in favor of the process objectives. This,...

A Molecular Dynamics Study of the Dissolution of Asphaltene Model Compounds in Supercritical Fluids
DownloadSpring 2011
The demand for a new solvent to treat oilsands was behind the purpose of this project; molecular dynamics simulation was used in this study. Supercritical water, supercritical carbon dioxide and other selected organic solvents in their supercritical state were studied. Meso-tetraphenyl porphyrin...

Fall 2019
The spontaneous displacement of a fluid in another immiscible one on a solid surface is essential for many technical applications, such as painting, detergency, bitumen extraction and enhancing oil recovery. This project was motivated by exploring a process of high viscosity bitumen displaced by...

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...

Spring 2011
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...

A study of the colloidal stability of mixed abrasive slurries of silica and ceria nanoparticles for chemical mechanical polishing
DownloadFall 2011
Slurry stability is an important factor in Chemical Mechanical Polishing (CMP) efficiency. However, few studies have been done in this respect. In settling tests at pH 4, adding various amounts of ceria to colloidal silica slurries was shown to change the stability of the resulted mixed abrasive...

Characterization of mature fine tailings in the context of its response to chemical treatment
DownloadFall 2010
Continuous accumulation of Mature Fine Tailings (MFT) is a major challenge to oil sands industry. To reduce the inventory of MFT through development of novel tailings treatment technologies, it is essential to understand the stabilization mechanism of fine solids in MFT. This project aims at...

Spring 2010
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...
