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...
Probing Deformable Oil-Water Interfaces by Atomic Force Microscopy and Cascade Partial Coalescence MeasurementsDownload
Phase separation of stable oil-in-water and water-in-oil emulsions poses major challenges for a variety of industries, including the petroleum industry. The stability and destabilizing of petroleum emulsions highly depend on interfacial properties such as surface/interfacial charges, interfacial...
A Surface Forces Apparatus (SFA) was used in this study to investigate the fundamental surface forces in oil sand processing research. Asphaltene coated surfaces were chosen as the research topic due to the critical role of asphaltenes in oil sands processing, from bitumen extraction, froth...
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...
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...
Asphaltenes are polyaromatic compounds present in crude oils, which are defined as being soluble in aromatic solvents and insoluble in n−alkanes. The partition of self−associated asphaltene aggregates at oil−solid and oil−water interfaces is the root cause of a number of major problems...
