“…Therefore, we use the same terminology throughout this article. Letting subscript s and superscript b refer to the solvent and bitumen, respectively, we can write the equality of fugacity for the dissolved gases in the gas and bitumen phase at equilibrium condition as: Mehrotra and Svrcek [19] Proposed model 1.79 287.85-371.35 2.14-10.95 Kariznovi et al [3] 8.89 Eastick et al [5] 6.8 A 3152.545 Mehrotra and Svrcek [2] 1.9 Yu et al [14] Proposed Huang and Radosz [9] 5.675 Huang and Radosz [8] 5.44…”

Prediction of solubility of CH₄, C₂H₆, CO₂, N₂ and CO in bitumen

An accurate model to calculate the solubility of light hydrocarbons (methane, CH 4 and ethane, C 2 H 6 ) and non-hydrocarbon gases (carbon dioxide, CO 2 , nitrogen, N 2 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 (CH 4 , C 2 H 6 , CO 2 , N 2 and CO) in bitumen from five reservoirs in Alberta, Canada. The Peng-Robinson (PR) equation of state (EoS) is used to treat the gas phase. The proposed model is then verified using available experimental solubility data of light solvents in bitumen, and good agreement is observed. The experimental data cover wide ranges of pressures and temperatures. The results show that the proposed model represents the available solubility data of light hydrocarbons (CH 4 and C 2 H 6 ) and non-hydrocarbon solvents (CO 2 , N 2 and CO) in bitumen with absolute average relative deviations of <4.2% and 5.4%, respectively. These results can be applied to heavy oil and bitumen recovery processes.

“…Experimental studies of the phase equilibria of a number of carbon dioxide + bitumen systems have been reported by different researchers (Robinson et al, 1980;Robinson and Sim, 1981;Svrcek and Mehrotra, 1982;Mehrotra and Svrcek, 1984, 1985a, 1985bFu et al, 1985;Mehrotra et al, 1989;Yu et al, 1989;Huang and Radosz, 1990;Xu and Hepler, 1990). As shown in Figure 1, the experimental conditions have spanned wide ranges of temperatures and pressures.…”

An apparatus for measuring the solubility of gas in liquid and that of liquid or solid in gas has been constructed. The apparatus can be used at system temperatures ranging from 20 to 70°C and at system pressures up to 15 MPa. The solubilities were determined by means of gravimetric measurements. The solubilities measured in this study for the carbon dioxide+n‐decane and carbon dioxide + naphthalene systems agree very well with the literature values. The vapor‐liquid equilibria of the carbon dioxide+Peace River bitumen system at 45 and 55 °C were studied. The new data indicate that the supercritical‐fluid carbon dioxide can extract a fair amount of the light components from Peace River bitumen.

The addition of hydrocarbon or nonhydrocarbon gases to steam can have a beneficial effect on the performance of steam-based processes for recovery of heavy and extraheavy oils. The performance of these newly developed techniques depends on the amount of solvent dissolved in the oil and the variation of oil viscosity with temperature. Thus, full understanding of the quantitative effects of the solvent on heavy-oil viscosity and phase behaviors is crucial for feasibility studies, design, and prediction of fieldscale processes.Thus, the aim of this research is the development of an understanding of the phase behavior of carbon dioxide (CO 2 )/Athabasca-bitumen mixtures. It includes both experimental and modeling studies of solubilities and saturated-liquid densities and viscosities over a wide range of temperatures (up to 200 C), approaching the conditions of in-situ steam processes and pressures up to 6 MPa.Experimental results indicate that the dissolved gas in bitumen leads to a significant oil-viscosity reduction, and the effect is greater at lower temperature and higher pressure. The gas-saturated-bitumen densities change slightly with the dissolution of CO 2 . The modeling results show that the measured solubilities are represented adequately by the modified Peng-Robinson equation of state (Robinson and Peng 1978), with an average absolute relative deviation (AARD) of 7.5%. The saturated-liquid densities are also correlated with equation-of-state and effective-liquid-density approaches, with 0.77 and 0.41% AARDs, respectively. The viscosity data are reasonably matched with the modified Pedersen corresponding state (Pedersen and Fredenslund 1987).
