Characterization of mature fine tailings in the context of its response to chemical treatment
DownloadFall 2010
Continuous accumulation of Mature Fine Tailings (MFT) is a major challenge to oil sands industry. To reduce the inventory of MFT through development of novel tailings treatment technologies, it is essential to understand the stabilization mechanism of fine solids in MFT. This project aims at...

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...

The use of microalloyed steels have accelerated exponentially in the past few decades due to their better mechanical properties as compared to traditional carbon steel. One of the main factor that contribute to their high strength and toughness values is the presence of uniformly dispersed fine...

Spring 2017
During the past several decades, the relationship between microstructure and mechanical properties of high strength microalloyed steels has been extensively studied in an effort to improve the fracture toughness and strength of these types of steels, without appreciably increasing steel...

Thickened tailings technology is implemented in some oil sands operations in order to recycle warm process water, thereby reducing net water draw, and to reduce the size of tailings impoundment areas. The rheology of thickened tailings is complex and time-dependent, and the underlying mechanism...

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...

Hydrothermal Treatment of Low Rank Coal for Making High Solid Loading and Stable Coal Water Slurries
DownloadFall 2014
The objective of this research is to understand the effect of hydrothermal dewatering (HTD) on surface properties, stability and rheological behavior of lignite water slurry (LWS). The surface forces between coal particles are found to be attractive after HTD, which is proven by contact angle and...

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...

Grade 91 steel is one of the most important 9-12% Cr creep strength enhanced ferritic (CSEF) steels used in fossil-fuel fired power plants. A narrow heat-affected zone with heterogeneous structures is generated in the base metal, due to non-equilibrium phase transformations during the arc welding...

MODELLING THE RHEOLOGY OF COMPLEX FLUIDS : Cases of Bitumen and Heavy Oils at low temperatures.
DownloadFall 2011
As complex fluids such as heavy oil or bitumen pass from the field to process units, structural and compositional changes occur that are intimately linked with pressure (P), temperature (T), and shear histories. In this exploratory work, a modified Structural Kinetics Model is used to calculate...
