Modeling of Pressure Dependence of Interfacial Tension Behaviors of Supercritical CO2 + Crude Oil Systems Using a Basic Parachor Expression
Parachor based expressions (basic and mechanistic) are often used to model the experimentally observed pressure dependence of interfacial tension (IFT) behaviors of complex supercritical carbon dioxide (sc-CO2) and crude oil mixtures at elevated temperatures. However, such modeling requires various input data (e.g. compositions and densities of the equilibrium liquid and vapor phases, and molec...
متن کاملDynamic interfacial tension at the oil/surfactant-water interface.
We have used dynamic interfacial tension measurements to understand the structure of the ordered monolayer at the hexadecane/water interface induced by the presence of surfactant molecules. No abrupt changes in the interfacial tension (gamma) are observed during the expansion and contraction cycle below the interfacial ordering temperature (Ti) as observed for alkanes in contact with air. The l...
متن کاملInterfacial Tension of Electrolyte Solutions
A theory is presented to account for the increase in surface tension of water in the presence of electrolyte. Unlike the original “grandcanonical” calculation of Onsager and Samaras, which relied on the Gibbs adsorption isotherm and lead to a result which could only be expressed as an infinite series, our approach is “canonical” and produces an analytic formula for the excess surface tension. F...
متن کاملModeling Interfacial Tension in Liquid−Liquid Systems Containing Electrolytes
A comprehensive model has been developed for calculating the interfacial tension (σ) in liquid−liquid systems with or without electrolyte components. The model consists of an equation for computing the interfacial tension of two-liquidphase nonelectrolyte systems and an expression for the effect of the electrolyte concentration. The dependence of the interfacial tension on the electrolyte conce...
متن کاملAn empirical technique for prediction of nucleation mechanism and interfacial tension of potassium chloride nanoparticles
Prediction of the nucleation mechanism is one of the most critical factors in the design of a crystallization system. Information about the nucleation mechanism helps to control the size, shape, size distribution, and purity of the produced crystals. When the crystallization method is used for producing nanoparticles, the nucleation mechanism should be predicted. In this study, an empirical cor...
