A Model Study on Water Soluble Polymeric Nanofibers for Rapid Flocculation and Enhanced Dewatering of Fine Oil Sands Tailings Simulated Through KaolinDownload
Nanofibers are fibers with diameters lower than 100 nm, traditionally made from natural or synthetic polymers. Properties of nanofibers, such as low density, controllable surface functionality, and high surface area to volume ratio, allowed researchers to use them in a multitude of applications...
This research comprises four integral parts. Each part focuses on one aspect of the general problem of drug delivery by respiration. The morphological features of human respiratory tract, the dynamics of inhaled pharmaceutical particles, and the mechanics of inhaler devices are particularly taken...
Application of Coagulation/Flocculation followed by Sedimentation for Treating Urban Combined Sewer OverflowsDownload
Combined Sewer Systems are commonplace in the United States and the major cities in Canada. These systems consist of both sanitary and stormwater lines which, when combined, create the potential for large surges of wastewater during storm conditions known as Combined Sewer Overflows (CSOs). CSOs...
A study was conducted to evaluate the properties and processes influencing the rate and magnitude of volume decrease and strength gain for oil sand fine tailings resulting from a change in bitumen extraction process (caustic versus non-caustic) and the effect of adding a coagulant to caustic fine...
This research aims to assist in the assessment of tailings management technologies through the development of a dynamic simulation model. The developed model (TMSim) incorporates the mine plan, various stages of dewatering including classification, pre- and post-deposition dewatering, and an...
The research was conducted to investigate effect of hydrodynamic conditioning on the flocculation of the oil sands fine tailings. The main focus was the effect of shearing on the structure of flocculated aggregates and the extent of reflocculation occurring upon cessation of shearing. An...
In bitumen recovery from oil sands, a percentage of the bitumen is lost to tailings. The effect of fugitive bitumen on fines settling and consolidation in tailings ponds remains controversial. In the current study, the settling performance of mature fine tailings (MFT) in response to flocculant...
Extending Depletion Flocculation Phase Behavior Models to Partially Soluble and Aggregating Colloids—AsphaltenesDownload
Mixtures of colloids + non-adsorbing polymers + good solvents are well known to exhibit multiphase behaviors that are driven by the depletion flocculation mechanism where one phase, designated a colloid gas, is largely comprised of polymer and solvent, while the other phase, designated a colloid...
Flocculation and dewatering of kaolinite suspensions and oil sands mature fine tailings using dual polymersDownload
The development of a method to consolidate and dewater Athabasca oil sands mature fine tailings (MFT) is one of the major challenges facing Alberta’s oil sands industry. This thesis presents studies performed on the flocculation and dewatering of kaolinite suspensions (the major clay component...
