Protecting Worker Safety in Alberta by Enhancing Hazard Identification and Control for Hazards Associated with Tailings Facilities, Dams, and Systems
DownloadSpring 2019
My research was motivated by a fatality that occurred at an oil sands tailings operation on January 19, 2014, when a worker drowned in an underground cavern which formed under a leaking tailings transport system. At the time of the incident, the organization and workers did not know that ground...

Reclamation of Unconventional Oil Processed Water through the Adsorption of Naphthenic Acids by Carbon Xerogel
DownloadFall 2017
This study examines the use of carbon xerogel (CX) material for the adsorption of naphthenic acids (NAs). The adsorption of NAs is crucial for the reclamation of unconventional oil processed water, more specifically Alberta’s oil sands process-affected water (OSPW). CX material is synthesized at...

Regenerable Composites for Removal of Organic Dye in Aqueous Media and Water in Heavy Oil and the Associated Interaction Mechanism
DownloadSpring 2018
Water plays an indispensable role in all aspects of life, including farming, domestic and industrial uses. In industries, water has been extensively applied in mining, production and surface treatment, producing a large quantity of contaminated water that threatens human health, endangers...

Removal of Heavy Metal Ions and Diethylenetriamine Species from Solutions by Magnetic Activated Carbon
DownloadSpring 2013
Even though activated carbon is widely used in the removal of contaminants from effluents, it is difficult to be completely recovered by screening or classification. In this project, we prepared a magnetic form of activated carbon (M-AC) by co-precipitation of iron oxides onto activated...

Removal of Organic and Inorganic Contaminants from Oil Sands Tailings using Carbon Based Adsorbents and Native Sediment
DownloadFall 2013
The extraction and refinement of oil sands bitumen produces substantial quantities of liquid tailings and solid coke. Tailings contain metals and naphthenic acids, which require remediation before mine closure. Adsorption is a potential remediation technique which may reuse stockpiled petroleum...

Spring 2016
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....

Study on Adsorption of Inorganic-organic Hybrid Polymers and Flocculation of Oil Sands Tailings
DownloadSpring 2013
Two inorganic-organic hybrid polymers, Al(OH)3-polyacrylamide (Al-PAM) and Fe(OH)3-polyacrylamide (Fe-PAM) were synthesized and used in flocculating model tailings (5 wt% kaolin suspensions) and laboratory extraction tailings. For comparison, a commercial anionic flocculant, partially hydrolyzed...

Synthesis and Characterization of Electrospun Activated Carbon Nanofibers Reinforced with Cellulose Nanocrystals for Adsorption Applications
DownloadFall 2019
Cellulose nanocrystals (CNCs) are emerging nanomaterials with desirable characteristics including biodegradability, renewable sources, high aspect ratios, high surface area, and high strength. Polyacrylonitrile (PAN) is the most commonly used polymer precursor for electrospinning due to its high...
