Asphalt pavements are the most common type of pavements in North America. Increasing traffic demand, harsh weather conditions, and the tendency for infrastructure operators to reduce the cost (and, therefore, the frequency) of maintenance are the major reasons for asphalt performance improvement...

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...

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...

Fall 2015
Oil sands found in Athabasca and Cold Lake regions of Northern Alberta form Canada’s primary source of energy reserves. Asphaltenes, a significant part of bitumen is often considered to be the least valuable component of crude oil due to various factors such as difficulty in transporting and...

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...

Biological Treatment of Naphthenic Acids and Other Organic Compounds in Oil Sands Process-Affected Waters
DownloadFall 2014
The Alberta oil sands contain one of the world’s largest reserves of oil - over 169 billion barrels of bitumen are economically recoverable with current extraction technologies. Surface mining, whereby the ore is extricated from the earth and bitumen is obtained via a hot water extraction...

Bioremediation of oil sands process affected water sourced naphthenic acid fraction compounds
DownloadFall 2020
Current development of Alberta’s oil sands region requires large volumes of water, leading to an abundance of oil sands process affected water (OSPW). OSPW contains naphthenic acid fraction compounds (NAFCs) which have been found to contribute extensively to OSPW toxicity. Degradation of this...
