During the extraction of crude oil or bitumen, stable water-in-oil emulsions are inevitably formed. The emulsified water contains chloride ions and other organic acidic compounds that cause severe corrosion problems to the downstream plant equipment, creating operational and safety issues and...

Characterization of asphaltene molecular structures by cracking under hydrogenation conditions and prediction of the viscosity reduction from visbreaking of heavy oils
DownloadSpring 2013
The chemical building blocks that comprise petroleum asphaltenes were determined by cracking samples under conditions that minimized alterations to aromatic and cycloalkyl groups. Hydrogenation conditions that used tetralin as hydrogen-donor solvent, with an iron-based catalyst, allowed...

Characterization of Athabasca asphaltenes separated physically and chemically using small-angle X-ray scattering
DownloadFall 2010
Athabasca asphaltenes were characterized using small-angle X-ray scattering (SAXS) with synchrotron radiation. Two methods were used to separate asphaltenes from Athabasca bitumen. Conventional chemical separation by precipitation with n-pentane, and physical separation realized by passing...

In this study, we describe the use of different silica materials to separate vanadium compounds from Asphaltenes. We used high performance flash chromatography separation method to separate asphaltenes at different solvent strengths on sea sand. The separation conditions were optimized for flow...

To understand the water cycle on Mars, details of mass and energy transfer between the surface and the atmosphere are of importance. A complete model, involving transient variations of the water in gaseous and solid phases in the atmosphere and the regolith, is developed and solved numerically...

Rankin, Robert , Degeling, Alex W., Watt, Clare E.
We introduce a new methodology that allows the construction of wave frequency distributions due to growing incoherent whistler-mode waves in the magnetosphere. The technique combines the equations of geometric optics (i.e., raytracing) with the equation of transfer of radiation in an anisotropic...

Control of D-Spacing and Graphitic Defects in Asphaltene-Derived Hard Carbons for Energy Storage
DownloadSpring 2024
With the increasing demand for energy storage and declining lithium stores around the globe, sodium is emerging as an alternative source due to its natural abundance and similar reaction kinetics and chemical properties to lithium. While sodium-ion and lithium-ion batteries started development at...

This thesis presents a thorough examination of the corrosion and fouling behaviour of crude oil at refining conditions on industrially applicable heat transfer surfaces. The depletion of light sweet crude oil reserves means that the processing of ever heavier and more sour crude oils is...

In recent years, the use of self-associating block copolymer based drug delivery systems have attracted increasing attention as nanoscopic carriers for the encapsulation and the controlled delivery of water insoluble drugs. Currently, most of the drug formulations proceed by “trial and error”...
