Characterization of bitumen is a necessary step to perform phase equilibrium computations involved in bitumen production and processing. This study presents a methodology for bitumen characterization using a residue curve map. A fugacity–activity coefficient approach is applied to model the thermodynamic equilibrium of the species in the gas and liquid phases. The Peng–Robinson equation of state (PR-EoS)...
An accurate model to calculate the solubility of light hydrocarbons (methane, CH4 and ethane, C2H6) and non‐hydrocarbon gases (carbon dioxide, CO2, nitrogen, N2 and carbon monoxide, CO) in bitumen is required for the optimal design of bitumen and heavy oil recovery processes and transportation. In this work, we used the Krichevsky–Ilinskaya equation to predict the solubility of light solvents (CH4...
