Characterization of mature fine tailings in the context of its response to chemical treatment
DownloadFall 2010
Continuous accumulation of Mature Fine Tailings (MFT) is a major challenge to oil sands industry. To reduce the inventory of MFT through development of novel tailings treatment technologies, it is essential to understand the stabilization mechanism of fine solids in MFT. This project aims at...

CO2-Responsive Surfactants for Enhancing Heavy Oil Recovery: from Fundamentals to Bench-Scale Demonstrations in Canadian Oil Sands Extraction
DownloadSpring 2020
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...

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...

Dynamic Demulsification Mechanism of Asphaltene-Stabilized Water-in-Oil Emulsions by Ethylcellulose
DownloadFall 2015
In previous studies, nontoxic and biodegradable ethylcellulose (EC) was shown to be capable of breaking water-in-diluted bitumen emulsions. Nevertheless, the demulsification mechanism of EC has not been correlated to its effect on the physical properties of stabilizing interfacial asphaltene...
