Beyond Viscosity—How Density, Vibration and Interfacial Tension Affect Solvent Aided Bitumen Production
DownloadFall 2016
Bitumen and heavy oil comprise a significant percentage of proven oil reserves globally. The environmental impacts of producing these resources with current technologies is a concern for environmentalists, oil producing companies, resource rich jurisdictions and society at large. Dilution of the...

Bubble Pressure Measurement and Modeling for n-Alkane + Aromatic Hydrocarbon Binary Mixtures
DownloadFall 2017
Commonly-used cubic equations of state (EOS) over predict the bubble point pressures (BPPs) for binary long-chain n-alkane + aromatic mixtures and frequently predict the incorrect phase diagram type. In this work, BPPs for 15 representative n-alkane + aromatic hydrocarbon binary mixtures were...

Fall 2021
Fluid transport within confinement is important for many lab-scale and industrial-scale technological processes ranging from membrane separation, enhanced oil recovery, CO2 sequestration to drug delivery systems. At the industrial scale, confined liquids are often quite complex as they consist...

Mimicking the Behaviors of Oil Contaminated Clays Using Functionalized Silica Nanoparticles
DownloadSpring 2018
Fine sand and clay particles arise naturally in diverse industrial and environmental remediation contexts. Organic compounds for example from oil production or oil spills can adsorb on their surface and influence their oil water interfacial behaviors. To isolate the impact of contamination and...

Phase Behavior Modeling of Asymmetric n-Alkane + Aromatic and Naphthenic Hydrocarbon Mixtures
DownloadSpring 2016
Global phase behavior calculations based on 150 n-alkane + aromatic and n-alkane + naphthenic hydrocarbon binary mixtures were performed. These calculations were compared with experimental measurements whenever possible, and additional measurements were made as part of this work. The widely used...

Predicition of the molecular structure of ill-defined hydrocarbons using vibrational, 1H, and 13C NMR spectroscopy
DownloadFall 2009
This represents a proof-of-concept study of the appropriateness of vibrational and NMR spectroscopy for predicting the molecular structure of large molecules on the basis of a library of small molecules. Density Functional Theory (DFT) B3LYP/6-311G was used generate all spectra. 20 model...

Fall 2013
There are currently no reliable methods for predicting liquid heat capacities of ill-defined hydrocarbons, such as bitumen and heavy crude oils and their partly processed fractions. Estimation techniques for liquid phase isobaric heat capacity of pure compounds include corresponding state and...

Fall 2011
Liquid crystalline domains were observed in fractions of heavy petroleum. Through a combination of polarized light microscopy and Photoacoustic Infrared Spectroscopy, liquid crystals were shown to form on the exterior surface of their parent materials. Analysis of materials using Differential...
