The water-based extraction process has been almost exclusively used in the current industry for Athabasca oil sands extraction to produce bitumen and heavy oil. However, the current method is facing various challenges, primarily including high energy

Atomic force microscopy (AFM) is frequently used to elucidate complex interactions in emulsion systems. However, comparing results obtained with “model” planar surfaces to curved emulsion interfaces often proves unreliable, because droplet curvat

SARA fractionation separates crude oil into fractions of saturates (S), aromatics (A), resins (R), and asphaltenes (A) based on the differences in their polarizability and polarity. Defined as a solubility class, asphaltenes are normally considered a

A surface forces apparatus (SFA) was used to measure the intermolecular forces between a biodegradable demulsifier (ethyl cellulose, EC) and asphaltenes immobilized individually on molecularly smooth mica surfaces in an organic solvent. A steric repu

The ongoing generation of mature fine tailings (MFT) or fluid fine tailings (FFT) from surface mining activities of the oil sands industry in Canada has been a contentious issue for many years. In the absence of large-scale processing facilities, man

A major drawback associated with current hot or warm water-based bitumen extraction processes is the high consumption of energy. To address this issue, an aqueous–nonaqueous hybrid bitumen extraction process (HBEP), in which a portion of the diluen

After successful isolation of the most interfacially active subfraction of asphaltenes (IAAs) reported in the first part of this series of publications, comprehensive chemical analyses including ES-MS, elemental analysis, Fourier transform infrared (

The asphaltene fraction of crude oil is commonly considered to be responsible for the formation of highly undesirable, stable water-in-crude oil emulsions and rag layers. We developed a new procedure for subfractionation of asphaltenes based on their
