TH62676B - Methods for dispersing hydrocarbon impurities in fluids used in hydrocarbon process. - Google Patents

Abstract

DC60 Method of suspension, dissolution, or viscosity reduction of hydrocarbon clogs. Includes heavy oils, tar, asphaltene, polynuclear aromatic hydrocarbons, coke, polymers, light oils, oxidized hydrocarbons and their decomposition products. Heat, and similar substances in fluids in contact with process equipment for hydrocarbons include Exposure to clogs with effective doses of halogen-free organic solvents containing The density is higher than that of water at the process temperature. Methods of dispersing, dissolving, or reducing the viscosity of impurities Hydrocarbons including heavy oil, tar, asphaltene, polynuclear aromatic hydrocarbons, coke, polymers, light oils, hydrocarbons are oxidized and produce hydrocarbons. heat, and similar substances in fluids in contact with process equipment for hydrocarbons which It combines by touching impurities with an effective amount of organic solvent that Halogen free, which has a higher density than water at process temperatures.
