“…Although interfacial tension data for the CO 2 /H 2 O system are widely available in the literature [6,[8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26], only the studies of Park et al [16], Kvamme et al [19], Chiquet et al [6], Bachu and Bennion [21], Chalbaud et al [22], Bikkina et al [24] and Shariat et al [25] have considered the effect of CO 2 dissolution on the density of the aqueous phase and taken the values of density from experiments or models.…”

“…At these conditions, pure CO 2 will be in a supercritical state (T c ~ 304.13 K and P c ~ 7.38 MPa) and with densities higher than 662 kg·m -3 . Due to its key role in the design of the processes mentioned above, many studies have been conducted on the experimental measurement of the IFT of the CO 2 /H 2 O system during the last two decades [6,[8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. In most of these studies the pendant drop method has been used to perform these measurements over a wide range of experimental conditions.…”

“…In fact, numerous workers have measured the interfacial tension of the (CO 2 + H 2 O) system [65,[72][73][74][75][76][77][78][79][80][81][82][83][84][85]. However, as discussed by Georgiadis et al [65], there is significant disagreement between some of these sources and a number of possible causes can be identified; these include the effects of trace impurities diffusing to the interface (especially in long-duration experiments), imperfect temperature regulation, and inaccuracy in the density difference between the two coexisting phases.…”

“…d e , d s and H parameters can be determined with a binary filtering technique with a digital imaging software (Akutsu et al, 2007;Rushing et al, 2008;Alotaibi and Nasr-El-Din, 2009). Prior to each experiment, the optical cells and other wetted parts of the equipment were thoroughly cleaned with toluene or acetone and then dried by blowing nitrogen gas.…”
