Résumé -Approche informatique pour l'étude des propriétés physico-chimiques de fraction pétrolière lourde (350 °C + ) -Le traitement et la valorisation des fractions pétrolières lourdes nécessitent une étude très détaillée dans la mesure où le pétrole contient un très grand nombre de composants différents (paraffines, oléfines, naphtènes, arômes). Afin de caractériser les fractions, il est indispensable de déterminer les propriétés thermodynamiques et thermophysiques des différents éléments. Ce travail présente une approche informatique qui peut être utilisée pour l'évaluation et l'estimation des propriétés des fractions pétrolières lourdes. La fraction pétrolière est divisée en un nombre arbitraire de pseudo-composants. Des cas d'étude ont été illustrés pour trois résidus lourds, issus d'un nombre égal de pétroles bruts "X, Y et Z". La procédure nécessite en entrée le point d'ébullition, la courbe de distillation et la densité volumique de l'ensemble de la fraction lourde. Les méthodes existantes, issues des corrélations disponibles dans la littérature et des standards industriels, ont été principalement employées pour estimer les propriétés basiques (le point d'ébullition normal, la densité et facteur de caractérisation de Watson), les propriétés thermodynamiques (masse molaire et propriétés critiques) et les propriétés thermophysiques (viscosité cinématique, conductivité thermique, capacité calorifique et pression de vapeur saturante). La méthode développée s'est montrée être un outil efficace pour calculer les propriétés des fractions pétrolières avec précision, quand les informations de départ sont disponibles. La prédiction des propriétés montre de bonnes correspondances avec les résultats obtenus auparavant dans les laboratoires de recherche LDPS/LOPCA de l'UNICAMP, avec un écart global absolu inférieur à 10 %. (paraffins, olefins, naphthenes, aromatics) require an in-depth evaluation. In order to characterize them, their thermodynamic and thermophysical properties must be determined.

SUMMARYA three-parameter corresponding states (CS) model is developed, importing methods formerly studied for the volumetric representation of #uids. The three parameters are critical temperature, pressure and a viscosity scaling factor de"ned from experimental saturated liquid viscosity data or, when these are unavailable, from a single experimental point. Two reference #uids are chosen both for their factor value and because the corresponding viscosity dedicated equations (VDE) are available. On the basis of the three-parameter CS model proposed by Teja et al. for volumetric properties, the reduced viscosity of a third #uid is obtained in reduced P, ¹ variables interpolating that of the two reference #uids, calculated at the same reduced temperature and pressure, by .Where the transport property is known along the saturation line at least, an improvement is introduced by correcting the factor with a temperature-dependent function "tted on these data. The model is then extended to mixtures using the one--uid model approach, in a completely predictive mode with respect to the mixture.The accuracy for both pure #uids and mixtures is comparable with that of the reference #uids' equations, while in the unimproved and improved mode the amount of input data is very limited. Also, comparison with a four-parameter CS model and with an ECS model con"rms the accuracy of the present technique. Considering the predictive nature of the model and the scattering of the available experimental data, the mean accuracy is good and more than satisfactory for the purposes of technical applications.
