High-Float Emulsion Residue: A New Rheological Model Based on the Existence of a Yield Stress
DownloadFall 2016
“High-float” (HF) emulsions are dispersions of micron-sized bitumen droplets in water, with a special type of anionic surfactant functioning as stabilizer. By allowing the water to evaporate from an HF emulsion, what remains is called a “high-float emulsion residue.” Although indistinguishable in...

The rheological properties of heavy oil and bitumen depend on factors such as temperature, pressure, diluent type and diluent composition, as well as sample shear and thermal histories and shear conditions during measurements. Each of these factors can affect the value of apparent viscosity...

Fall 2013
In industrial visbreaking processes, the conversion typically takes place at ~450 °C and the extent of conversion is limited by the coking propensity of the feed. Some of the older literature on bitumen upgrading reported that it was possible to substantially upgrade the straight run product at...

The demand for accurate bitumen-pentane mass transfer data was the main motivation behind this research. Difficulties such as complex phase behavior, high viscosity and opacity of the hydrocarbon invariably lead to failure of conventional techniques to measure mass transfer coefficients...

Microwave Heating Of Non-Aqueous Oil Sands Extraction Gangue: Study Of Optimal Cyclohexane-Water Mass Ratio And Solvent Recovery Rate
DownloadFall 2023
Non-aqueous bitumen extraction processes (NAE) of mined oil sands ore have been investigated to circumvent the environmental and operating limitations of the current hot water-based technology. However, one primary challenge of NAE is a solvent recovery that meets environmental and economic...

Natural Zeolite Catalysts for the Integrated Cracking, Waterless Extraction and Upgrading of Oilsands Bitumen
DownloadSpring 2012
Canadian oilsands bitumen represents one of the largest petroleum reserves in the world, but extraction of that resource raises significant environmental, operational and quality-related challenges. Current extraction processes are water intensive, generating high volume tailings ponds that are...

Oil Upgrading by Molecular Rearrangement and Cracking: A Study Using Model Compounds and Natural Chabazite
DownloadFall 2015
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...

On Organic Liquid Crystal Transfer from Bitumen-Rich to Water-Rich Phases: A Combined Laboratory and SAGD Field Study
DownloadSpring 2014
Hydrocarbon-based liquid-crystal domains were observed in unreacted heavy fractions extracted from Athabasca bitumen and bitumen derived hydrocarbon resource fractions. Transfer of these organic crystalline domains to the water-rich phase during SAGD production is explored here because there...
