A Model Study on Water Soluble Polymeric Nanofibers for Rapid Flocculation and Enhanced Dewatering of Fine Oil Sands Tailings Simulated Through Kaolin
DownloadFall 2018
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...

Amylopectin-graft-hydrolyzed-poly(methyl acrylate) (AP-g-H-PMA) Flocculants for the Treatment of Oil Sands Tailings
DownloadSpring 2020
The extraction of bitumen from the Alberta oil sands reserves has long been a major economic contributor to the Canadian society, but the impact this industry has had on the environment has raised concerns worldwide. The main problems are how to reclaim the area and reduce the number of tailings...

A multi-purpose settling column was designed to determine settling rate and sediment height allowing the in-situ measurement of yield stress and drainage without disturbing the sediment particle network. The settling column was applied to studying flocculation/densification of model oil sands...

Hand injuries, due to impact, are common workplace injuries. Many work gloves afford impact protection through design of add-on components known as bumpers. Glove design criteria are complex (e.g., limitations from human factors, dexterity, use case, hand size variability) and commercial bumpers...

The kinetics of the thermal decomposition of Athabasca vacuum residue (AVR) has been studied by thermogravimetric analysis. Three heating rates of 0.5, 10 and 25 K/min were used to investigate the consistency of kinetic parameters. The Weibull and Gaussian distribution functions were found to be...

Effect of Addition Flowrates of Grafted Polymers on the Flocculation of Kaolinite Suspensions and Oil Sands Mature Fine Tailings
DownloadSpring 2023
Bitumen extracted from oil sands has been a major source of wealth for Canada, but it comes at a high price because the Clark hot water process generates large volumes of tailings which must be stored in ponds that threaten the environment. These tailing ponds must be treated to meet the land...

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...
