Electrocoalescence of Water Droplets in Oil Emulsions: Effect of Electric Fields, Surfactants, and Chemical DemulsifiersDownload
Stabilization of water-in-oil droplets during bitumen extraction and refining process poses a major challenge in the oil sands industry. These crude oil emulsions are stabilized by rigid films at water droplet-oil interfaces. The salty water remaining in oil causes equipment corrosion, catalyst...
Mechanisms of Aggregation and Separation of Water and Solids from Bitumen Froth using Cluster Size DistributionDownload
The large-scale corrosion and equipment damage caused by water and solids respectively in bitumen froth necessitate their removal using various methods. This study is aimed at understanding how water and solids aggregate (water-water, water-solid and solid-solid) in bitumen froth and what the...
A bacterial colony constitutes a complex microcosm which is equipped with a wide range of defensive adaptations that allow the colony to survive adverse environmental conditions and predation. The extreme resilience of bacteria in colonies has been a subject of continued research for nearly two...
Interactions between droplets were studied using two lattice Boltzmann methods (LBMs). The Shan-Chen LBM, in which repulsive forces between fluids maintain phase separation, was used to simulate systems with three immiscible components. The simulations demonstrated the three equilibrium...
