(FR) PRÉDICTION DE LA PRÉCIPITATION D’ASPHALTÈNE À HAUTE TEMPÉRATURE
Abstract:
(EN) A method for determining a relationship between the ratio of solvent power to critical solvent power and the threshold light paraffin content of a hydrocarbon fluid is provided. The method comprises: dividing the plurality of hydrocarbon fluids into subgroups, based on the ratio of solvent power to critical solvent power; for each of the subgroups, determining the threshold light paraffin content, said threshold light paraffin content being the light paraffin content of the hydrocarbon fluids at the point at which the fouling tendency of the hydrocarbon fluids exceeds a fouling threshold; and determining a relationship between the ratio of solvent power to critical solvent power and the threshold light paraffin content.
(FR) L'invention concerne un procédé permettant de déterminer la relation existant entre le rapport du pouvoir solvatant sur le pouvoir solvatant critique et la teneur seuil en paraffine légère d'un fluide d'hydrocarbure. Le procédé consiste à : diviser la pluralité de fluides d'hydrocarbures en sous-groupes, sur la base du rapport du pouvoir solvatant sur le pouvoir solvatant critique ; pour chacun des sous-groupes, déterminer la teneur seuil en paraffine légère, ladite teneur seuil en paraffine légère correspondant à la teneur en paraffine légère des fluides d'hydrocarbure lorsque la tendance à l'encrassement des fluides d'hydrocarbure dépasse un seuil d'encrassement ; et déterminer une relation entre le rapport du pouvoir solvatant sur le pouvoir solvatant critique et la teneur seuil en paraffine légère.
