Abstract
AbstractA comprehensive model is presented for predicting the liquid‐mixture viscosity of bitumen and its fractions diluted with toluene. The proposed model is based on the Walther two‐parameter viscosity‐temperature correlation and a simple viscosity mixing rule. New viscosity data at 22‐100°C are presented for 14 blends of Cold Lake bitumen and its fractions with toluene. All of these data are well correlated by the Walther correlation with AAD < 2%. The predictions from a recently proposed simple mixing formula for toluene‐bitumen blends viscosity are well within an order of magnitude of the data. The blend viscosity predictions are improved substantially by use of a temperature‐dependent viscous interaction parameter. For predicting the viscosity of toluene‐diluted whole bitumen, the bitumen is characterized both as a “black‐oil” and as a mixture of five fractions or pseudocomponents. The calculation procedure for the viscosity of toluene‐diluted bitumen is outlined and the two characterization approaches are evaluated.
