Application of coagulation-flocculation process for treating oil sands process-affected water
DownloadFall 2011
Oil Sands Process-Affected Water (OSPW) is generated from oil sands operation processes such as mining, extraction, and upgrading. Currently, accumulated OSPW is temporarily stored in tailings ponds which are toxic to the environment and must be treated for either reuse or safe discharge in the...

A multi-purpose settling column was designed to determine settling rate and sediment height allowing the in-situ measurement of yield stress and drainage without disturbing the sediment particle network. The settling column was applied to studying flocculation/densification of model oil sands...

The extraction of bitumen from oil sands in Alberta, Canada, leads to the creation of tailings that are contained in lake-sized ponds under zero discharge policy. Stratification of tailings over time leads to the formation of mature fine tailings (MFT), an oil based emulsion containing residual...

Applications of Remote Hyperspectral Sensing in the Characterization of Alberta's Oil Sands Tailings
DownloadSpring 2016
The bitumen production from oil sands surface-mining operations produces large volumes of mineral wastes called tailings. Characterization of the oil sands tailings is of importance to monitor their state for trafficability and reclamation issues, to assess the tailings operation performance, and...

Assessing the long-term impact of acid deposition and the risk of soil acidification in boreal forests in the Athabasca oil sands region in Alberta, Canada
DownloadFall 2012
Significant amounts of SO2 and NOx have been emitted from the Athabasca oil sands region (AOSR) in Alberta, Canada, in the past several decades. The impact of acid deposition on forest ecosystems and the risk of soil acidification were assessed in jack pine (Pinus banksiana) and trembling aspen...

Fall 2011
Oxidative desulfurization of oil sands bitumen as pre-refining methodology to improve bitumen quality in the absence of catalysts was studied. It has potential advantages such as employing a cheap reagent (air) and moderate processing conditions (<180 °C, autogenous pressure). The specific aims...

Canada has the world’s largest oilsands reserves. Part of the reserves is being considered as marginal and is not profitable to recover using current technology. Autoxidation (oxidation with air) is a potential upgrading strategy to produce more valuable products from the oilsands derived bitumen...

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...

Biodegradation of Hydrocarbons in Bitumen: Exploring Plant-Assisted and Microbial Stimulation Techniques
DownloadFall 2020
While bitumen is one of the oldest construction materials in the world and currently provides an important fuel needed to sustain our modern lifestyle, the disturbances caused by extracting and refining this material are considerable, with 895 km2 of land being disturbed in Alberta as of 2018...
