“…(21); therefore, the new proposed influence is more accurate than the one in Eq. (20) suggested in previous investigations [11][12][13][14][15][16]. For C 1 /nC 6 binary system, the performance of these two influence parameters is approximately the same.…”

“…In recent years, three groups of empirical expressions have been used to determine the influence parameter of the gradient theory: (1) constant influence parameter [6][7][8]; (2) temperature dependent influence parameter [9,10]; (3) the influence parameter based on the densities of the vapor and liquid phases [11][12][13][14][15][16]. The first group makes the theory easer.…”

“…On the other hand, it was concluded that the second group lead to a significant improvement, but it has some limitations, for example, the temperature dependent influence parameter used by Zuo and [9,17,18] is not possible to be applied under supercritical conditions so that the reduced temperature should be set to a single value. In recent years, the third group of influence parameter of the gradient theory [11][12][13][14][15][16] has been successfully applied to refrigerant mixtures and water/gas systems. The third group of influence parameter has shown the potential to overcome the limitations of the first and second groups.…”

“…Furthermore, a new correlation based on the densities of the vapor and liquid phases have been proposed. The performance of new suggested influence parameter has been also compared with the previous proposed influence parameter in [11][12][13][14][15][16]. Furthermore, the performance of suggested influence parameter has been discussed.…”

The laboratory determination of CO2‐brine interfacial tension is very important for estimating the storage capacity of saline aquifers during the CO2 sequestration process. In this paper, we measured CO2 and the brine interfacial tension using the pendant‐drop method at a temperature of 285–300 K and pressure of 3–9 MPa. The brine was composed of Na+, K+, Ca2+, and Mg2+ cations with different molalities. The experimental results indicate that interfacial tension increased with temperature and salinity but decreased with pressure until it reached a plateau. At the same temperature and pressure, the plateau value increased with increasing brine salinity for all types of brines used in this work. Moreover, the plateau exists whenever the CO2 is liquid. The interfacial tension between CO2 and brine with bivalent cations is larger than that between CO2 and monovalent brines. Finally, we established an empirical equation based on the relationship between interfacial tension and temperature, pressure, and salt molality grounded on experimental data, which allows the evaluation of CO2–brine interfacial tension values with a mean deviation of ±4 mN·m−1. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd.
