Development of a predictive model for the VAPEX process.
(University of Waterloo, 2019-01-11)Heavy oil in-situ recovery in Canada is largely achieved through energy intensive and en- vironmentally detrimental steam assisted gravity drainage (SAGD). By exchanging steam for a vapour solvent, it has been shown ... -
Ethyl Cellulose Nanoparticles in Multiphase Systems: Foams, Emulsions, and Porous Media
(University of Waterloo, 2017-08-18)Adsorption-mediated self-assembly of ethyl cellulose (EC) nanoparticles at fluid interfaces, driven by reduction in interfacial energy, is shown to lead to stabilization of emulsions and foams. A multiscale approach is ... -
Fibers-based Porous Structures for Oil Absorption Applications
(University of Waterloo, 2018-01-18)In the age of environmental awareness the persistent problem of oil spills and their frequent occurrences have urged researchers to advance and innovate the methods for oil spill remediation. Besides being a significant ... -
Multi-Phase Multi-Component Equilibrium Flash Calculations for CompFlow Bio using Modified Volume-Translated Peng- Robinson Equation of State
(University of Waterloo, 2017-05-24)Numerical modelling of fluid flow and transport in reservoir engineering problems is a challenging task, given variability and uncertainty in the physical properties of rock, the complexities of multi-fluid interaction at ... -
On the Prediction of Gas Hold-up in Ebullated Bed Reactors
(University of Waterloo, 2019-09-19)Commercial ebullated bed reactors (EBRs) are three-phase fluidized bed systems used for hydroprocessing (upgrading) of bitumen, a major Canadian resource. The objective of this thesis is to improve the understanding of the ... -
Pore Network Modeling of Hydrodynamic Dispersion and Irreversible Adsorption of Nanoparticles in Partially Saturated Granular Media
(University of Waterloo, 2022-07-20)The transport of nanoparticles in porous media, whether deliberate or accidental, is of critical importance in several fields including migration of contaminants, wastewater clean-up, and enhanced oil recovery. Pore scale ... -
Remediation of Weathered Light Nonaqueous Phase Liquids by Persulfate: In-Situ Performance Assessment and Numerical Modeling
(University of Waterloo, 2021-08-25)Light nonaqueous phase liquids (LNAPLs) petroleum hydrocarbons (PHCs) subsurface contamination is complex and poses considerable risks to human health and the environment. The PHC contaminated sites are often difficult to ...
