METHOD FOR REMOVING ASPHALTENE DEPOSITS

摘要

Compositions comprising at least one C4-Q30 olefin or oxidation product t hereof and kerosene or an aromatic solvent are particularly effective for us e in removing asphaltene and asph.altene-containing organic deposits and in preventing or reducing the precipitation and deposition of asphaltenes from hydrocarbon fluids. When added to heavy oils comprising asphaltenes, alone o r in combination with dispersants and further inhibitors, the invented compo sitions lower viscosity and pour point, and aid in preventing asphaltene pre cipitation during transport and in combustion...
