Accelerated Dewatering and Drying Treatment of Oil Sands Tailings by Electrical Resonant Auto-TransformerDownload
Canada has world’s third largest oil reserves in the form of oil sands and 20% of those are easily accessible by surface mining. The hot water bitumen extraction process has been used since 1967 and the process produces vast amount of tailings which are stored in ponds. Tailings ponds pose a...
Interfacial activity of SAGD PW endogenous surfactants, humic acids (HAs), and their interaction dynamics with naphtha-diluted Alberta oil sand bitumen (AOSB) present in model SAGD produced water has been addressed in the first part of this PhD thesis. Dynamic interfacial tension σ(t) between oil...
One of the central puzzles concerning the interaction of low Reynolds number (Re<<1) fluid transport with bacterial biomass is the formation of filamentous structures called bacterial streamer. Bacterial streamers can be tethered at one or both ends to solid surfaces, while the rest of the...
Biofilm formation in porous media is of significant importance in many environmental and industrial processes such as bioremediation, oil recovery, and wastewater treatment. In the present study, we fabricated a porous media mimic inside a microfluidic device to observe the growth of bacteria in...
Electrical heating has been proposed in the past as an alternative to conventional water based thermal methods for reducing viscosity of bitumen in oil sands reservoirs. This could reduce or even eliminate water use and associated problems like inefficient heat transfer in the reservoir, poor...
This thesis presents a thorough examination of the corrosion and fouling behaviour of crude oil at refining conditions on industrially applicable heat transfer surfaces. The depletion of light sweet crude oil reserves means that the processing of ever heavier and more sour crude oils is...
Development of an Electronic Nose for Detection of Volatile Organic Compounds Based on Nanoporous Microcantilevers by Using Photothermal SpectroscopyDownload
An electronic nose for identification and quantification of volatile organic compounds (VOCs) mixtures was developed using a nanopore-enhanced photothermal cantilever deflection spectroscopy (PCDS). PCDS provides highly selective detection of vapor mixtures of VOCs from specific molecular...
The direct conversion of mechanical energy into electricity by nanomaterial-based devices offers potential for green energy harvesting. One of the main challenges for mechanical energy harvesting technologies, such as piezoelectric or triboelectric generators, is to provide sufficient current...
Current thin film technologies and devices require high quality deposits in order to fully extract the potential of the material. Pulsed laser deposition (PLD) is one physical vapour deposition method used to synthesize these high quality complex films. PLD offers the distinct advantage of being...
Developing miniature instrumentation for biosensing has attracted an extensive interest due to the demand for selective and sensitive detection of multiple targets at extremely low concentrations with exceedingly small sample volumes. Micro/nano mechanical sensors, such as microcantilevers (MCL),...
