TH75132A - Methods for dispersing hydrocarbon impurities in fluids used in hydrocarbon process. - Google Patents

Abstract

DC60 Methods of suspending, dissolving, or reducing the viscosity of hydrocarbon blockers. This includes heavy oils, tar, asphaltine, polyonuclear aromatic hydrocarbons, coke, polymers, light oils, oxidized hydrocarbons and produce a decomposition effect. Hot, and similar substances in fluids come into contact with process equipment for hydrocarbons, including Contact clogging with effective amounts of halogen-free organic solvents which have Its density is higher than water at process temperature. Methods of dispersion, dissolution, or impurities viscosity reduction. Hydrocarbons that include heavy oils, tar, asphaltine, polynuclear aromatic hydrocarbons, coke, polymers, light oils, hydrocarbons are oxidized and produce a decomposition effect. Heat, and similar substances in fluids in contact with process equipment for hydrocarbons which Combined by touching impurities with a powerful quantity of organic solvents that Halogen free, which has a higher density than water at process temperature.
