A Surface Forces Apparatus (SFA) was used in this study to investigate the fundamental surface forces in oil sand processing research. Asphaltene coated surfaces were chosen as the research topic due to the critical role of asphaltenes in oil sands processing, from bitumen extraction, froth...

The confined impinging jet reactor gives efficient mixing performance as required for fast reactions. In this work the mixing performance of CIJR is characterized through three measures: estimates of the energy dissipation, micromixing efficiency based on the yield of a homogeneous...

Interfacial properties have a regulatory role in processes which involve the coexistence of different phases. Although such macro-scale properties are determined by the intrinsic nature of the interface-sharing phases, it is possible to alter them in favor of the process objectives. This,...

Caustic is the most commonly used process aid to improve processability of mineable oil sands ores in the Athabasca region. The addition of caustic adjusts the pH of the extraction process, disperses clays, and acts as a water softener. Understanding how these changes affect the fundamental...

To understand the role of caustic addition and its effect on the bitumen extraction process, a novel flow cell and a Denver Cell extraction unit were utilized. This allowed for the comparison of sodium hydroxide and ammonium hydroxides effect on real oil sands ores. Several ores (A1, C-ore,...

Two major kinds of natural surfactants are released during oil sands extraction: carboxylic acids (naphthenic acids) and sulfonic acids. In this study, commercial surfactants were used as standards to establish the suitable analytical methods with optimized experimental and instrumental...

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....

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...

Bitumen froth from oil sands extraction typically contains 60 wt.% bitumen, 30 wt.% water, and 10 wt.% solids. To meet downstream process specifications, the water and solids in bitumen froth have to be removed. The objective of this study is to identify the source of the water reporting to the...

The spontaneous displacement of a fluid in another immiscible one on a solid surface is essential for many technical applications, such as painting, detergency, bitumen extraction and enhancing oil recovery. This project was motivated by exploring a process of high viscosity bitumen displaced by...
