Experimental and Numerical Studies on the Diffusion of CO2 from Oil to Water

Diffusivity of CO2 in H2O: A Review of Experimental Studies and Molecular Simulations in the Bulk and in Confinement

“…The experimental data (orange symbols) of Chiquet fall in the range ± (25–50)% from the SA correlation. Finally, the experimental data (black symbols) of Tewes and Boury, Li et al, Basilio et al, and Ahmadi et al exhibit deviations which can be significantly higher than 50%.…”

“…The experimental data (orange symbols) of Chiquet 166 fall in the range ± (25−50)% from the SA correlation. Finally, the experimental data (black symbols) of Tewes and Boury, 167 Li et al, 168 Basilio et al, 124 116 and circles the experimental data by Cadogan et al 113 The red solid line denotes the calculations of the diffusion coefficient of CO 2 in H 2 O at various temperatures and 20 MPa using the correlation of Mutoru et al, 61 and the orange solid line denotes the calculation using the correlation of Versteeg et al 161 The dashed lines denote the correlations examined in this work (SA-type: magenta; VTF-type: blue; ARR-type: black): (a) Extrapolation and comparison with recent experimental data at higher pressures. (b) The parameters for the three correlations are re-evaluated to include recent experimental data (Lu et al, 116 Cadogan et al 113 ).…”

Numerical Simulation of CO2 Diffusion in a Multiliquid-Phase System Using Moving Mesh Technology

“…Li et al considered the influence of oil–water interface on the mass transfer of CO 2 between the oil phase and water phase. They proposed a numerical method to calculate the pressure drop and diffusion coefficient of CO 2 when CO 2 diffusing from oil phase to water phase …”

“…They proposed a numerical method to calculate the pressure drop and diffusion coefficient of CO 2 when CO 2 diffusing from oil phase to water phase. 39 However, CO 2 diffusion is confronted with more complicated situations in the solvents assisted CO 2 flooding technologies. In the above technology, many auxiliary agents, such as surfactants and polymers, are employed to assist CO 2 in improving oil recovery.…”
