Spring 2017
Interactions mechanisms of deformable air bubbles and liquid droplets play critical roles in many established and modern industrial processes. Understanding the interaction mechanisms of oil droplets and air bubbles is of fundamental and practical importance to solve many challenging issues,...

Spring 2023
The extraction of bitumen from oil sands is an energy and water-intensive process that produces a tailings byproduct containing sands, clays, water, and residual bitumen. Larger particles eventually settle out of the tailings, but fine particles – stabilized by the residual bitumen – remain...

Understanding stability of water-in-diluted bitumen emulsions by colloidal force measurements
DownloadSpring 2011
Removal of emulsified water is a challenge in oil sands and heavy oil processing. The flocculation and coagulation of emulsified water droplets depend on the interactions between the water droplets covered mainly by asphaltenes and oil-contaminated fine solids. To quantitatively evaluate the...

Understanding Surface Forces and Interaction Mechanisms in Mineral Flotation by Atomic Force Microscopy
DownloadFall 2019
Bubble-particle interactions are ubiquitous and crucial to mineral fotation. The bubble-particle attachment process is mainly governed by three surface forces: van der Waals (vdW), electrical double-layer (EDL), and hydrophobic (HB) forces. Atomic Force Microscopy (AFM) has become the most...

Understanding the Chemistry of Conversion of Model Compounds and Biomass by Hydrous Pyrolysis Based on Spectroscopic Data Using Data Fusion, Data Mining, and Chemometrics
DownloadFall 2019
Encoding the presence of multispecies in a complex system, difficulty in characterizing the physical constituents of the products with analytical instruments along with developing the causality or modeling between these groups are some major challenges in a complex system such as biomass...

Understanding the Deposition and Molecular Interaction Mechanisms of Substrate-supported Functional Coatings
DownloadFall 2017
Functional coatings have been extensively exploited for creating surfaces with desired functionalities in numerous engineering applications, which have received increasing attention over the past few decades. The objectives of this thesis research were to develop stable, hydrophobicity-tunable...

Understanding the Effects of Hydrogen, Hydrostatic testing and Mill- scale on SCC of Pipelines in Near-Neutral pH Environment
DownloadFall 2016
Near-neutral pH stress corrosion cracks (NNpH SCC) are developed under coating disbondments on the external surface of pipelines where the surface of pipeline is exposed to the soil solution. NNpH SCC initiation and early stage of growth is mainly governed by the dissolution process of steel....

Spring 2013
Sodium hydroxide (NaOH) is used as a chemical additive to enhance bitumen recovery from oil sands by surface-mining extraction process. The addition of NaOH adjusts the pH of the slurry water to pH ~8.5 (approximate pH of process water). The change in pH of oil sand slurry affects the process...

Understanding the Role of Caustic Addition: A Comparison of Sodium Hydroxide and Ammonium Hydroxide
DownloadSpring 2012
To understand the role of caustic addition and its effect on the bitumen extraction process, a novel flow cell and a Denver Cell extraction unit were utilized. This allowed for the comparison of sodium hydroxide and ammonium hydroxides effect on real oil sands ores. Several ores (A1, C-ore,...

Spring 2016
In this study, a two-step flocculation method by combining anionic and cationic polymeric flocculants on the treatment of oil sands tailings was investigated. Compared to conventional flocculation by using a single anionic or cationic polymer, which has been a widely exploited procedure for...
