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...
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...
Seven Ni-WC tubular wires utilized in this study were characterized by the nickel sheath area, powder composition, and overall initial carbide volume fraction of the wire prior to welding. The electrical resistivity of steel, stainless steel, and Ni-WC welding consumables were measured from...
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...
Life Cycle Assessment of Transportation Fuels from Canada’s Oil Sands through Development of Theoretical Engineering ModelsDownload
Oil sands in Canada are significant in fulfilling the current and the future energy demands of North America. The development of these resources, besides the increased awareness in global carbon management, has given way to various policy regulations such as the Low Carbon Fuel Standard (LCFS)...
Influence of Amendments and Soil Depth on Available Nutrients and Microbial Dynamics in Contrasting Topsoil Materials Used for Oil Sands ReclamationDownload
As of December 2013, the cumulative area disturbed by oil sands mining in NE Alberta was 896 km2 out of an estimated final footprint of 4,800 km2 – all of which will require reclamation. Expensive handling costs and scarce soil resources necessitate judicious management and application of...
A Study on the Effect of Temperature and Pressure on the Removal of Cyclohexane from Non-Aqueous Extraction GangueDownload
Solvent based extraction has the potential to supplant the current hot water based extraction process as the industry standard method for recovering bitumen from mined oil sand. It has the potential for higher bitumen recovery that is less sensitive to the grade of oil sand ore being processed....
Oil Upgrading by Molecular Rearrangement and Cracking: A Study Using Model Compounds and Natural ChabaziteDownload
As demand for fuel increases, new technologies that can convert heavy oil and bitumen into light fuels are needed. Natural zeolites have been proven to catalyze reactions that decrease molecular weight, density, nitrogen, and metals content as well as vacuum residue content when mixed with raw...
Non-aqueous extraction technologies are currently being investigated as an alternative to the conventional water based process for extracting bitumen from oil sands. The reduced dependence on fresh water and land for creation of tailing ponds makes non-aqueous technologies a greener alternative....
The remediation of oil sands wastes such as fluid fine tailings (FFT) and oil sands process-affected water (OSPW) are of increasing concern in the oil sands industry. End pit lakes are one remediation option currently being researched at commercial scale in Base Mine Lake (BML) operated by...
