Bitumen has been extensively extracted from oil sands through the Clark Hot Water Extraction (CHWE) process. This extraction process uses hot water and alkaline conditions to remove bitumen from oil sands ores. The tailings produced by this process are mixtures of sand, clays, residual bitumen,...

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...

Achieving forest recovery on previously forested well sites in northern Alberta is an on-going challenge for the oil and gas industry. Thirty-three experimental oil sands exploration (OSE) sites were constructed and reclaimed between 2004 and 2006 in northeastern Alberta. Our goal was to...

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...

Development of compact fluorescent spectrometers and field deployable optical solids content monitoring devices
DownloadSpring 2015
Two techniques were used to develop industrial and environmental sensing devices: fluorescence spectrometry and light scatter. The focus of the thesis is to develop real-time, portable and economical sensors using these techniques for environmental detection and management of tailings slurries. A...
