Improving the Modeling of Hydrogen Solubility in Heavy Oil Cuts Using an Augmented Grayson Streed (AGS) Approach

Abstract: est souvent préconisée dans l'industrie pour calculer la solubilité de l'hydrogène dans des coupes pétrolières. Il se fait cependant que sa précision se dégrade rapidement pour les coupes lourdes. Une amélioration est proposée dans ce travail, basée sur l'ajout d'un terme de Flory dans le calcul du coefficient d'activité. L'étude de la solubilité de l'hydrogène dans les n-alcanes du n-C 7 au n-C 36 fait apparaître que la constante de Henry diminue avec la masse molaire. L'analyse de ce comportement suggère la … Show more

“…EXPERIMENT AND DISCUSSION OF THE RESULTS. Liquid fuel is a multicomponent mixture of organic substances Henry's law [11] for a multicomponent mixture, taking into account the Wohl's expansion [12], can be represented as: gives a significant deviation from experimental data [7]. This is due to the difficulty in determining the exact proportions of organic matter in the fuel.…”
