Characterization of the dissolved organic matter in steam assisted gravity drainage boiler blow-down water
DownloadFall 2012
The presence of high concentrations of dissolved organic matter (DOM) and total dissolved solids (TDS) in the boiler blow-down water (BBD) causes severe equipment fouling during the SAGD operation. For effective BBD management, a detailed understanding of the BBD chemistry is important. In this...

Chemical and Biological Oxidation of Naphthenic Acids - where Stoichiometry, Kinetics and Thermodynamics Meet
DownloadFall 2016
Open-pit mining of Alberta’s oil sands deposits heavily depend on freshwater for the extraction of bitumen. It leaves 1.25 m3 oil sands process affected water (OSPW) per barrel of produced oil. In spite of years of research on treatment of OSPW, currently, there are no approved economic and...

Colloid Science of Sand Remediation: A Study Motivated by the Non-Aqueous Extraction of Bitumen from Oil Sands
DownloadFall 2014
The current water-based method of bitumen extraction requires withdrawal of fresh water from the Athabasca River — a practice which leads to the continual buildup of tailings ponds and other environmental concerns. As Alberta’s bitumen production is expected to more than double by 2020, there is...

Degradation of Naphthenic Acids from Oil Sands Process Water and Groundwater Using Chemical Oxidation
DownloadFall 2013
Naphthenic acids attribute to the toxicity of oil sands process water. Naphthenic acids quantification by Fourier Transform Infrared Spectroscopy depends significantly on which standard is used and Merichem naphthenic acids are a good standard. Naphthenic acids can be removed from oil sands...

Degradation of Recalcitrant Organics in Oil Sands Process Water (OSPW) Using Combined Electro-Oxidation and Electrochemically Activated Peroxymonosulfate (EO-PMS)
DownloadFall 2021
Abdelrahman, Ali Satti Abdellatif
In northern Alberta, the bitumen extraction process from oil sands ores consumes large amounts of water, resulting in the generation of huge volumes of oil sand process water (OSPW). Currently, the treatment of OSPW is considered a major challenge facing the oil sands industry. Moreover, among...

The formation of stable water-in-oil emulsions during bitumen extraction poses problems for water separation from diluted bitumen, which leads to equipment corrosion and catalyst fouling in downstream operations. Demulsifiers are used to break the stable emulsions and assist the separation of...
