چکیده
Cet article prsente une valuation des performances des quations d'tats (EoS) cubiques pour la prvision des comportements de phases des mlanges hyperbares. Il met en vidence un certain nombre de problmes auxquels il devrait tre rpondu d'une manire cooprative. Les points relatifs la dfinition des paramtres des EoS, tels que les coefficients d'interaction, les proprits critiques des composants hydrocarbons et la translation de volume sont examins. Plusieurs types dÕinformations ont t pris en compte dans cette tude : les donnes exprimentales dÕquilibre liquide-vapeur (ELV), les donnes compositionnelles et volumtriques issues dÕquilibres isothermes jusquÕ 4 000 bar pour les mlanges binaires, les donnes PVT jusquÕ 2 000 bar pour des mlanges binaires et des systmes synthtiques multicomponants.

Experience in Norsk Hydro with Cubic Equations of State
The paper presents some specific applications of cubic equations of state (EOS) in Norak Hydro and points out some aspects of such equations that one should be aware of when using them or when developing new equations. Is is emphasized that the use of EOS to calculate vapor-liquid equilibrium is inherently empirical. Activity coefficients predicted’ for some systems by the Soave-Redlich-Kwong (...
متن کاملCubic-Plus-Association Equation of State for Asphaltene Precipitation in Live Oils
We apply a cubic-plus-association equation of state (CPA-EOS) to study the asphaltene precipitation in live oils from temperature, pressure, and composition effects. The live oils are characterized by considering the pure components, the pseudo-hydrocarbon components, and the hydrocarbon residue. The hydrocarbon residue is further divided into the “heavy” component and asphaltenes. The asphalte...
متن کاملNew Local Composition-Equation of State Mixing Rules for High Pressure Vapor-Liquid Equilibria Using EOS/AE
In this study using Equation of State/ Helmholtz excess energy function, EOS/AE, two new local composition-Equation-of State mixing rules, LCEOS1 and LCEOS2 were developed in which the energy interaction parameters were expressed in terms of attractive and repulsive parameters of the cubic equation of state. The EOS/AE models are applied for equilibrium calculation of nat...

Mixtures of carbon dioxide and secondary butyl alcohol at high pressures are interesting for a range of industrial applications. Therefore, it is important to have trustworthy experimental data on the high-pressure phase behavior of this mixture over a wide range of temperatures. In addition, an accurate thermodynamic model is necessary for the optimal design and operation of processes. In this...
متن کاملPhase Diagrams of Fe-Si Alloys under High Pressures
Introduction Iron is the most abundant element in the Earth’s core. However, the density of the outer core is about 10% lower than the density of iron at the pressure and temperature conditions of the outer core, indicating the presence of a low-atomic-weight component (such as H, C, O, Si, or S) in the core [1]. There is also evidence that the inner core may be less dense than pure iron and th...
