Fall 2009
The work presented in this dissertation provides a novel technique of manipulation of colloidal entities during membrane filtration based on an AC electrokinetic phenomenon called dielectrophoresis. First, the influence of dielectrophoretic (DEP) forces created on a membrane surface to levitate...

Characterization of natural zeolite membranes for H2/CO2 separations by single gas permeation
DownloadFall 2011
Hoseinzadeh Hejazi, Sayed Alireza
Membrane-based processes have the potential to overcome the limitations of conventional hydrogen separation techniques such as high energy consumption and environmental concerns. Natural zeolite membranes have recently been shown to demonstrate apparent molecular sieving of H2 from H2/CO2...

Coupling supercritical CO2 extraction with membrane separation leads to energy savings by recycling CO2 at supercritical state while separating extract components. Commercially available polyamide-based membranes are commonly used with coupled systems due to their availability and robust...

The fluids produced from a thermal enhanced recovery process such as steam assisted gravity drainage (SAGD) and cyclic steam stimulation (CSS) are pumped to the surface where bitumen and water are separated. This initial fluid is known as SAGD-PW (produced water). A potential way to effectively...

Extraction of Hydrocarbons from Bitumen and Bitumen-containing Process and Process Waste Streams using Supercritical Carbon Dioxide
DownloadSpring 2019
Extractions of hydrocarbons from bitumen and bitumen-containing process and process waste streams generated from surface mined oil sands were conducted using supercritical carbon dioxide (SC-CO2). Dynamic extractions were performed on a bench-scale batch supercritical fluid extraction (SFE)...

Forward Osmosis as an Approach to Manage Oil Sands Produced Water: Membrane Fouling and Organic Removal
DownloadFall 2017
Currently, large amounts of oil sands process-affected water (OSPW) are stored in tailing ponds, leaving its environmental impact a significant concern. To better manage OSPW, numerous treatment approaches have been investigated including adsorption, advanced oxidation and biological treatment,...

Natural zeolite-based membranes have recently shown promise in the separation of H2 from CO2 and hydrocarbons. However, these highly dense, naturally monolithic materials can suffer defects which disrupt the continuity of the zeolite micropores and create leak paths through the membrane. Cement...

Little is known about Vertex Operator Algebras (VOAs) which are neither semi-simple nor rational, and most of the work on such VOAs has been focused around specific examples such as the Singlet VOA. In this thesis, the relationship between subcategories of the module categories of the Singlet VOA...

Natural Clinoptilolite Composite Coated Stainless Steel Tubular Membranes for Water Softening and Desalination
DownloadSpring 2015
Water is an essential resource for life and sources of fresh water are limited. As population and industries are increasing around the world the need for reuse the water is increased. One of the most important industries in Alberta, Canada is oilsands industry. Steam assisted gravity drainage...
