Water-mediated adhesion of oil sands on solid surfaces at low temperature and possible solutions to mitigate adhesion
DownloadSpring 2022
Adhesion of frozen granular materials on solid surfaces creates various problems for surface cleaning, reduces the carrying capacity of vehicles, and increases energy consumption for inland transportation. Here in the first part of this thesis, water content demonstrates to determine the adhesion...

Thin film pyrolysis was used to thermally crack the pendant groups from asphaltene molecules. The cracked products were rapidly quenched to minimize further decomposition. The liquid products were condensed and collected, with over 91% material balance on the recovery of gas, liquid and coke...

Canada has the largest known reserve of oil in the world in the form of oil sands: an estimated 1.7 to 2.5 trillion barrels of oil are deposited in combination of the sand, water and clay. The presented research is devoted to bubble-solid surface interaction, which is one of the critical areas...

Study of biodiesel-assisted ambient aqueous bitumen extraction (BA3BE) for hydrocarbon production from mineable oil sands
DownloadFall 2019
Surface mining followed by Clark’s hot water bitumen extraction (HWBE) process has been employed in the current mineable oil sands industry for massive bitumen production. This method is faced with numerous challenges such as high energy consumption, limited bitumen quality, production from...

Many tailings treatment technologies rely on the use of water-soluble polyacrylamides (PAM) to flocculate fine solids. However, PAM-induced flocs are often loosely-structured and retain significant volume of water due to the hydrophilicity of PAM and fine clays in oil sands fine tailings....

The use of solvents for extraction of bitumen is attractive because no wet tailings are produced. Studies have already shown that hydrocarbon solvents can achieve the same level of bitumen recovery as the current aqueous extraction method. However, solvent recovery must be very efficient to avoid...

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....

Non-aqueous solvent extraction of bitumen from oil sands has the potential to replace the existing hot-water extraction process. The benefit of non-aqueous extraction process includes high bitumen recovery, reduction of fresh water demand for extraction and the elimination of resulting tailing...

Process industries involve processes that have complex, interdependent, and sometimes uncontrollable/unobservable features that are subject to a variety of uncertainties such as operational fluctuations, sensory noises, process anomalies, human involvement, market volatility, and so forth. In the...

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...
