Measurement and modeling of density and viscosity for mixtures of Athabasca bitumen and heavy n-alkane

The viscosity of bitumen is extremely high at ambient temperature and in order to produce and transport the bitumen, it is necessary to reduce its viscosity. One of the methods to reduce the bitumen viscosity is the dilution with liquid solvent. In this manuscript, the density and viscosity of bitumen, tetradecane, and their mixtures at different weight fractions have accurately been measured. The measurements were taken under conditions...
