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...
Study of biodiesel-assisted ambient aqueous bitumen extraction (BA3BE) for hydrocarbon production from mineable oil sandsDownload
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...
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...
Understanding the Role of Caustic Addition: A Comparison of Sodium Hydroxide and Ammonium HydroxideDownload
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,...
CO2-Responsive Surfactants for Enhancing Heavy Oil Recovery: from Fundamentals to Bench-Scale Demonstrations in Canadian Oil Sands ExtractionDownload
Interfacial properties at the oil-water interface are of key importance to various operations in the petroleum industry, especially in the aqueous-based heavy oil recovery process. However, different operation stages often require different interfacial properties, which could be conflicted with...
The formation of stable water-in-oil emulsions during oil sands extraction process causes a number of operational issues, such as equipment corrosion, storage and transportation problems. One common method for emulsion breakup in industry is to use chemical demulsifiers. The chemical demulsifiers...
The correlation between froth recovery and air recovery was established in a top-feeding mechanical flotation column. It was also found that the particles were stratified in froth layer, with hydrophobic particles (organic phase) concentrated in the upper region, and hydrophilic particles...
Mineral carbon sequestration (MCS) is a type of carbon storage based on natural rock weathering processes where CO2, dissolved in rainwater, reacts with alkaline minerals to form solid carbonates. Although MCS has advantages over other carbon storage techniques, an economic MCS process has not...
Theoretical study on reactivity of different sulfide collectors and their binding affinity toward Cu(II), Zn(II) and Pb(II) ions.Download
Collectors are one of the most important ingredients of froth flotation in mineral processing, as they selectively render the desired minerals more hydrophobic than others. Current crop of sulfide collectors interact with almost all sulfide minerals. This necessitates the use of complicated...
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...
