“…As shown in Figures –, the IFT for all binary and ternary studied systems is reduced as the temperature and pressure increase. These results agree with previous studies of binary and ternary systems, − and the developed ANN model accurately predicts this behavior. For the (H 2 O + CO 2 ) system, in the stuides by Chiquet et al (2007), Kvamme et al (2007), Georgiadis et al (2010), and Chow et al (2016), a sudden change in gradient is observed and this is due to IFT dependence on pressure, the aspect which is fully gathered by the current model that accurately predicts this change in gradient.…”

In this study, artificial neural networks (ANNs) determined by a neuro-evolutionary approach combining differential evolution (DE) and clonal selection (CS) are applied for estimating interfacial tension (IFT) in water-based binary and ternary systems at high pressures. To develop the optimal model, a total of 576 sets of experimental data for water-based binary and ternary systems at high pressures were acquired. The IFT was modeled as a function of different independent parameters including pressure, temperature, density difference, and various components of the system. The results (total mean absolute error of 3.34% and a coefficient of correlation of 0.999) suggest that our model outperforms other habitual models on the ability to predict IFT, leading to a more accurate estimation of this important feature of the gas mixing/water systems.

“…This could modify γ depending on the contact time between the drop of water at the end of the needle and the solution of TBP/Dodecane. This hypothesis is confirmed by the fact that even though the solubility of TBP in water is quite low (2.70×10 −5 mol fraction) 47) the action of TBP at the water/air interface is important since the surface tension of water saturated with TBP (γ＝31.7 mN・m −1 ) 49) is much lower than that of pure water (γ＝72 mN・m −1 ) . In any case, the values obtained in this work are close to those reported in the literature 28) .…”

ance of chemical stabilization of many compounds and produces a mechanically stable form of waste. Unfortunately, the stabilization of organic liquids (OL) in Ordinary Portland Cement (OPC) greatly retards and disrupts cement setting, and organic liquids generally form weak chemical bonds in cement unlike some inorganics 5,6) . Due to these disadvantages, geopolymers could be a solution to replace OPC for the incorporation of organic liquids and also for the treatment of OL waste.Since the resulting paste hardens to form a solid material (hardened GP) , mixing organic liquids (OL) with such aqueous suspensions 1, 2, 7, 8) has been recently described for the synthesis of porosity-controlled media, thermal insulating foams or filtration supports 9−13) and for the treatment of radioactive wastes 14,15) .In order to understand the immobilization of radioactive organic liquid wastes, alkanes 14,16) and paraffin oils 17) are used as model oils. The one-step incorporation process, which seems industrially more reasonable than the two-Abstract: The direct incorporation of low viscosity organic liquids (OL) such as dodecane and tributylphosphate (TBP) into fresh geopolymers (GP) is difficult and generally leads to variable amounts of un-incorporated OL remaining outside the hardened geopolymer. Experimentally, it is observed that a regular torque increase during OL incorporation corresponds to a suitable dispersion of the OL in the form of fine micrometric droplets. This can be obtained for TBP and dodecane by adding a small quantity of quaternary ammoniums salts (QAs) such as cetyltrimethylammonium bromide (CTAB). Shorter alkyl chains QAs, such as hexamethyltrimethylammonium (HMTA) can also be used but with a reduced efficiency. The positive impact of CTAB is then confirmed by the Washburn capillary rise method, showing that the interactions between TBP and CTAB-modified metakaolin are weaker compared to untreated powder. Finally, it is observed that the incorporation of TBP into geopolymer slurries is much easier than the incorporation of dodecane. The low interfacial tension measured between TBP and the activating solution (around 8 mN•m -1 ), contrasting with dodecane (29 mN•m -1 ), explains that the dispersion of TBP droplets in fresh metakaolin suspensions is more efficient.

Vapor−liquid interfacial properties of the binary systems (toluene + CO 2 ) and (toluene + N 2 ), as well as for the three pure components toluene, CO 2 , and N 2 , were studied using experimental and theoretical methods. Data on the surface tension and the relative adsorption were obtained from pendant drop experiments as well as from molecular dynamics (MD) simulations and density gradient theory (DGT) + perturbed-chain polar statistical associating fluid theory (PCP-SAFT). The experiments were carried out at temperatures between 303.15 and 373.15 K and pressures up to 5.7 MPa. MD and DGT calculations were carried out at 283.15, 303.15, 323.15, and 343.15 K in the entire composition range. MD and DGT were also used for studying the enrichment of the low-boiling component and the thickness of the interface. Furthermore, the vapor−liquid equilibrium (VLE) bulk phase properties were computed by MD and PCP-SAFT and compared to experimental data from the literature. The data from the different methods were found to be in good agreement throughout. The comparison of the results for the two studied mixtures provides insights into the link between phase behavior, interfacial properties, and molecular interactions.
