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...
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,...
Management of oil sands tailings from bitumen extraction operations remains a challenge for mineable oil sands producers. Promoting fine solids settling in tailings ponds is key to treating oil sands tailings. Present study explores two methods of tailings treatment – ATA process and polymer...
Solvents are ubiquitously used in oil sands extraction industry to enhance the separation of bitumen froth. With developing new technologies such as non-aqueous bitumen extraction, the need to track solvent interactions with oil sands components throughout the extraction process and to identify...
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...
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...
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...
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....
To better understand bitumen conditioning stage in oil sands extraction process a flow cell was designed to study bitumen liberation directly from sand grains, using real oil sand ore. A high-grade oil sand ore was subjected to various water temperatures and pH values to examine the bitumen...
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...
