Ozonation of asphaltene was conducted as modification method of asphaltene. A new method to facilitate the precipitation of asphaltene in water/n-pentane/bitumen emulsion was suggested with oxidized asphaltene. The ozonized asphaltene was characterized with various analysis. SARA removal efficiency was calculated with various dosage, solvent ratio, and degree of oxidation, when ozonized asphaltene was added. Also, ozonized asphaltene was applied to reduce viscosity of diluted bitumen (Dilbit) during transportation in pipeline. |
