“…The isobaric phase equilibria considered cover the temperature range between the UCEP and the melting curve of pure eicosane, on which the calculated isobars end. For this system the UCEP was determined by van der Kooi et al[11] at T = 307.37 K ± 0.15 K, P = 89 MPa ± 0.25 MPa, and a composition of the fluid phase of x C20H42 = 0.049 ±0.0012.…”

Cet article prŽsente une Žvaluation des performances des Žquations d'Žtats (EoS) cubiques pour la prŽvision des comportements de phases des mŽlanges hyperbares. Il met en Žvidence un certain nombre de probl•mes auxquels il devrait •tre rŽpondu d'une mani•re coopŽrative. Les points relatifs ˆ la dŽfinition des param•tres des EoS, tels que les coefficients d'interaction, les propriŽtŽs critiques des composants hydrocarbonŽs et la translation de volume sont examinŽs. Plusieurs types dÕinformations ont ŽtŽ pris en compte dans cette Žtude : les donnŽes expŽrimentales dÕŽquilibre liquide-vapeur (ELV), les donnŽes compositionnelles et volumŽtriques issues dÕŽquilibres isothermes jusquÕˆ 4 000 bar pour les mŽlanges binaires, les donnŽes PVT jusquÕˆ 2 000 bar pour des mŽlanges binaires et des syst•mes synthŽtiques multicomponants. PERFORMANCE OF CUBIC EOS AT HIGH PRESSURESThis paper presents an evaluation of the performance of cubic equations of state in the prediction of the phase behavior of hyperbaric mixtures. It points out a number of problems that should be resolved in a cooperative way. Items related to EoS parameter definitions such as interaction coefficients, critical properties of hydrocarbon compounds and volume translation are investigated. VLE experimental data, isothermal flash compositional and volumetric data up to 4000 bar as well as PVT data up to 2000 bar for binary mixtures and synthetic multicomponent systems have been considered in this study.Correlation and prediction results are presented with the translated and modified Peng-Robinson (t-mPR) EoS. It is shown that serious problems are encountered at high pressure, when extrapolated interaction coefficients are used. Prediction of saturation pressures of gas condensates is more satisfactory when binary interaction RESULTADO DE LAS ECUACIONES DE ESTADO CòBICAS DE ALTAS PRESIONESSe presenta en este art'culo una evaluaci-n de los resultados de las ecuaciones de estado (EoS) coebicas para la previsi-n de los comportamientos de fases de mezclas hiperb ‡ricas y se hace resaltar cierto noemero de problemas a que se deber'a poder responder de forma cooperativa. Se examinan los puntos relativos a la definici-n de los par ‡metros de las EoS, como, por ejemplo, los coeficientes de interacci-n, las propiedades cr'ticas de los componentes hidrocarbonados y la traslaci-n de volumen. Se han tenido en cuenta y debidamente comentados en el presente estudio, los datos experimentales de ELV, las isotermas flash molares y volumŽtricas hasta 4000 bar para mezclas binarias, as' como los datos PVT hasta 2000 bar para las mezclas binarias y los sistemas sintŽticos de componentes moeltiples.Tomando como punto de partida la ecuaci-n de Peng-Robinson (t-mPR) trasladada y modificada se presentan diversas correlaciones y resultados previsionales. Se demuestra que se habr ‡ de tropezar con serios problemas al alcanzar las altas presiones en caso de que se utilicen coeficientes de interacci-n extrapolados. Las previsiones de las presiones de saturaci-n de los gases de condens...
