| Abstract: | Athabasca bitumen was characterized by dividing it into sixteen pseudo components. Using mean boiling point, molecular weight and specific gravity data, the critical properties of the pseudo components were estimated from available correlations. Two approaches for the prediction of bitumen surface tension were investigated. It was found that the surface tensions predicted by the principle of corresponding states and the Rice-Teja correlations were in general agreement with the published experimental data. In addition, these models successfully predicted the effect of temperature on surface tension at temperatures greater than about 60°C. |
