CA 2567894

A method of dispersing, dissolving, or reducing the viscosity of hydrocarbon foulants including heavy oil, tars, asphaltenes, polynuclear aromatic hydrocarbons, coke, polymers, light oil, oxidized hydrocarbon and thermal decomposition products, and the like in fluids in contact with hydrocarbon processing equipment comprising contacting the foulant with an effective amount of a halogen-free organic solvent having a density greater than water at the processing temperature.

La présente invention concerne un procédé de dispersion, de dissolution ou de réduction de la viscosité de salissures d'hydrocarbure comprenant des huiles lourdes, des goudrons, des asphaltènes, des hydrocarbures aromatiques polynucléaires, du coke, des polymères, des huiles légères, des hydrocarbures oxydés et des produits de décomposition thermique, ainsi que des éléments similaires dans des fluides en contact avec des matériels de traitement d'hydrocarbures consistant à mettre en contact la salissure avec une quantité efficace d'un solvant organique exempt d'halogène possédant une densité supérieure à celle de l'eau à la température de traitement.
