Beyond Viscosity—How Density, Vibration and Interfacial Tension Affect Solvent Aided Bitumen ProductionDownload
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...
Colloid Science of Sand Remediation: A Study Motivated by the Non-Aqueous Extraction of Bitumen from Oil SandsDownload
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...
The non-aqueous extraction process involves dilution of mined oil sand with an organic solvent (the “diluent”), followed by separation of unwanted materials (clays, silica sand, connate water, etc.) from the diluted bitumen. The main focus of this research is on the removal of fines solids from...
Asphaltenes are the heaviest components in crude oil. It is generally believed that asphaltenes adsorbed at oil/water interface can form a protective layer to stabilize the water-in-oil emulsions. Therefore, it is of both fundamental and practical importance to understand the adsorption kinetics...
Fine sand and clay particles arise naturally in diverse industrial and environmental remediation contexts. Organic compounds for example from oil production or oil spills can adsorb on their surface and influence their oil water interfacial behaviors. To isolate the impact of contamination and...
Shale oil/gas resources are becoming an increasingly important energy resource. Compared to conventional reservoirs, shale generally consists of a large proportion of organic matters. Organic matter is mainly comprised of kerogen, within which a significant amount of nanopores may reside. Due to...
Physicochemical properties and microencapsulation process development for fish oil using supercritical carbon dioxideDownload
Fish oil is an excellent source of long chain polyunsaturated fatty acids (LC-PUFA), which can reduce the risk of cardiovascular disease in addition to other health benefits. However, the average intake of LC-PUFA in the Western diet is much lower than the recommended levels. Fish oil is prone to...
