Spring 2020
Albertan oil sands ores are becoming more difficult to process efficiently as the clay content of the ore increases and the grade of the ore worsens. A key to improving the extraction of bitumen from low-grade oil sands, thereby increasing the longevity of this critical resource, is reducing the...

Electrocoalescence of Water Droplets in Oil Emulsions: Effect of Electric Fields, Surfactants, and Chemical Demulsifiers
DownloadSpring 2019
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...

Estimation of the Evaporation Rate of an Isolated Water Microdroplet Subjected to Infrared Radiative Heating
DownloadFall 2014
A combined numerical-experimental investigation was performed to study the influence of infrared radiation on the evaporation of a single-component droplet in the range between 10 and 50 micrometers, under different environmental conditions of relative humidity and temperature of air. A numerical...

Estimation of the Life Cycle Greenhouse Gas Emissions of Bitumen-Derived Petroleum Fuels using Enhanced Solvent Extraction Incorporating Electromagnetic Heating (ESEIEH) and Toe-to-Heel Air Injection (THAI) Extraction Technologies
DownloadSpring 2019
There is increased focus on reduction of greenhouse gas (GHG) emissions to reduce global warming. Combustion of fossil fuels are a key contributor to emissions of GHG. Alberta is the largest hydrocarbon base in North America due to its oil sands deposit. Bitumen from oil sands is refined to...

Spring 2017
The formation of stable water-in-oil emulsions during oil sands extraction process causes a number of operational issues, such as equipment corrosion, storage and transportation problems. One common method for emulsion breakup in industry is to use chemical demulsifiers. The chemical demulsifiers...

Fall 2017
Although evaporation is considered to be a surface phenomenon, the rate of molecular transport across a liquid–vapor boundary is strongly dependent on the coupled fluid dynamics and heat transfer in the bulk fluids. Recent experimental thermocouple measurements of the temperature field near the...

Experimental investigation on evaporation induced convection in water using laser based measurement techniques
DownloadFall 2010
Recent studies showed that evaporation of water can induce surface tension gradients along the water surface and ultimately lead to convection, known as Marangoni convection. This study was devoted to visualization and characterization of the evaporation-induced, surface-tension-driven convection...

Extraction of Hydrocarbons from Bitumen and Bitumen-containing Process and Process Waste Streams using Supercritical Carbon Dioxide
DownloadSpring 2019
Extractions of hydrocarbons from bitumen and bitumen-containing process and process waste streams generated from surface mined oil sands were conducted using supercritical carbon dioxide (SC-CO2). Dynamic extractions were performed on a bench-scale batch supercritical fluid extraction (SFE)...

Spring 2024
A diffuse interface model to simulate a system of two immiscible liquids with surfactants is proposed. This model is based on a modified Ginzburg-Landau free energy functional to account for non-ionic soluble surfactants and couples the Navier-Stokes equations with two Cahn-Hilliard equations...
