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...

A Molecular Dynamics Study of the Dissolution of Asphaltene Model Compounds in Supercritical Fluids
DownloadSpring 2011
The demand for a new solvent to treat oilsands was behind the purpose of this project; molecular dynamics simulation was used in this study. Supercritical water, supercritical carbon dioxide and other selected organic solvents in their supercritical state were studied. Meso-tetraphenyl porphyrin...

The purpose of this study is to investigate the impact of solvent addition to bitumen froth on the wettability of froth solids. The wettability of solids determines the transportation/partitioning of the solids between phases, which in turn affects the solids and water rejection in a Clark hot...

Design, Synthesis, Characterization of a new pH-Responsive Copolymer and its Application in Oil Sands Tailings Treatment
DownloadSpring 2015
This research aims at treating mature fine tailings (MFT) with a novel pH-responsive copolymer poly (N,N-dimethylaminoethyl methacrylate-co-acrylamide-co-acrylic acid) p(DMAEMA-co-AM-co-AA). Compared with conventional polyacrylamide (PAM), the conformation and property of this novel copolymer can...
