Asphaltenes are the heaviest and the most polar fractions of crude oil and are defined as a
solubility class (typically soluble in toluene but insoluble in n-alkanes like n-heptane) …

This paper passes over the literature for residual oil characterization. The methods for
residual oil characterization are classified in: characterization based on physical and …

The relation between the chemical composition of bitumen and the physical properties, such
as viscosity or viscoelasticity is very important for the use of bitumen as an advanced …

Asphaltene precipitation and subsequent deposition are responsible for one of the major
flow assurance concerns in the oil industry. Recent experimental evidence found on the …

A comprehensive review of refractive index mixing rules of binary solutions is presented. All
published mixing rules, with the exception of the Wiener mixing rule, can be reformulated …

By coupling heat and mass transfer for C3H8/n-C4H10/CO2/heavy-oil systems as well as by
treating heavy oil as multiple pseudocomponents, a new technique together with its …

Asphaltene precipitation is considered a precursor of the plugging of oil wells and
subsurface equipment and is a topic of continuous interest among companies and academic …

The solubility parameter is considered to be a significant parameter for the chemical
industry. In this study, the quantitative structure–property relationship (QSPR) method is …

The exactitude of petroleum fluid molecular weight correlations affects significantly the
precision of petroleum engineering calculations and can make process design and trouble …

A generalized methodology has been developed to couple heat and mass transfer of a gas–
heavy oil system and a gas mixture–heavy oil system at high pressures and elevated …
