Spring 2013
Solvents are ubiquitously used in oil sands extraction industry to enhance the separation of bitumen froth. With developing new technologies such as non-aqueous bitumen extraction, the need to track solvent interactions with oil sands components throughout the extraction process and to identify...

In bitumen recovery from oil sands, a percentage of the bitumen is lost to tailings. The effect of fugitive bitumen on fines settling and consolidation in tailings ponds remains controversial. In the current study, the settling performance of mature fine tailings (MFT) in response to flocculant...

Fall 2010
The effect of slurry conditioning on bitumen recovery and bitumen froth quality has been studied by using three oil sands ores tested with a laboratory hydrotransport extraction system (LHES) and a Denver flotation cell. Tests with the LHES show that an increase in slurry conditioning time...

Probing Challenges of Asphaltenes in Petroleum Production through Extended−SARA (E−SARA) Analysis
DownloadSpring 2019
Asphaltenes are polyaromatic compounds present in crude oils, which are defined as being soluble in aromatic solvents and insoluble in n−alkanes. The partition of self−associated asphaltene aggregates at oil−solid and oil−water interfaces is the root cause of a number of major problems...

Carbon dioxide (CO2) was shown as a promising alternative for oil sands tailings treatment with economical and environmental benefits. This thesis aims to understand the role of CO2 addition in settling and densification of oil sands tailings. In this study, CO2 was pressurized into two...

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...

The correlation between froth recovery and air recovery was established in a top-feeding mechanical flotation column. It was also found that the particles were stratified in froth layer, with hydrophobic particles (organic phase) concentrated in the upper region, and hydrophilic particles...

Mineral carbon sequestration (MCS) is a type of carbon storage based on natural rock weathering processes where CO2, dissolved in rainwater, reacts with alkaline minerals to form solid carbonates. Although MCS has advantages over other carbon storage techniques, an economic MCS process has not...

Theoretical study on reactivity of different sulfide collectors and their binding affinity toward Cu(II), Zn(II) and Pb(II) ions.
DownloadSpring 2016
Collectors are one of the most important ingredients of froth flotation in mineral processing, as they selectively render the desired minerals more hydrophobic than others. Current crop of sulfide collectors interact with almost all sulfide minerals. This necessitates the use of complicated...

The confined impinging jet reactor gives efficient mixing performance as required for fast reactions. In this work the mixing performance of CIJR is characterized through three measures: estimates of the energy dissipation, micromixing efficiency based on the yield of a homogeneous...
