Nature of Asphaltene Aggregates
Energy & Fuels, 2018The size and fractal dimension of asphaltene aggregates were investigated for two Western Canadian bitumens diluted with n-heptane at concentrations above the onset of precipitation.

Impact of Asphaltene Surface Energy on Stability of Asphaltene-Toluene System: A Parametric Study.
Langmuir, 2018Asphaltene is a complex macromolecule whose abundance strongly affects the physical and interfacial properties of crude oil. Asphaltene molecules may precipitate during crude oil production/transportation, which may lead to plugging/clogging of wellbores,

Asphaltene Deposition during Bitumen Extraction with Natural Gas Condensate and Naphtha
, 2018Solvent bitumen extraction processes are alternatives to thermal processes with potential for improved economic and environmental performance. However, solvent interaction with bitumen commonly results in in situ asphaltene precipitation and deposition ...

Influence of Asphaltene Inhibitors on Wax and Asphaltene Deposition - Are Problems Associated?
Offshore Technology Conference Brasil, 2019Abstract Organic deposition formed at high temperatures in oil and gas production systems is commonly linked to instability of asphaltenes. Recent studies revealed that deposits collected in offshore production wells produced in Gulf of Mexico exhibited compositional variation pointing to a more complex fouling process than solely ...

Influence of Asphaltene Concentration on the Combustion of a Heavy Fuel Oil Droplet
Energy & Fuels, 2018Heavy fuel oils consist of a blend of middle distillates, mainly diesel fuel, and heavy oil residuals. Varying the fraction of the mixture changes the weight percentage of the asphaltene in the heavy fuel oil (HFO) sample.

Applied Clay Science, 1986
Abstract Asphaltene adsorption measurements with a well crystallized kaolin, a poorly crystallized kaolin, and a montmorillonite under anhydrous conditions and in the presence of water showed that the adsorption varied depending on the properties of the clay and the amount of water.
