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. Se describe un metodo para dispersar, disolver o reducir la viscosidad de ensuciantes de hidrocarburos en los que se incluyen petroleo pesado, alquitranes, asfaltenos, hidrocarburos aromaticos polinucleares, coque, polimeros, petroleo ligero, hidrocarburos oxidados y productos de descomposicion termica y los semejantes en fluidos en contacto con equipo de procesamiento de hidrocarburos, que comprende poner en contacto el ensuciante con una cantidad efectiva de un solvente organico libre de halogeno que tiene una densidad mayor que la del agua a la temperatura de procesamiento.
