Abstract
Viscosity is one of the important physical properties required by engineers
involved in pipeline shipment of heavy oil-solvent mixtures. The literature contains
numerous correlations for predictions of viscosities of a variety of binary liquid
mixtures. However, these equations are not suitable for heavy oil-solvent mixtures
of large viscosity ratios. This paper presents two modified Puttagunta et al [13]
viscosity correlations. The proposed new correlations have been verified using a
viscosity data base of about 300 points, out of which 205 are new data. The data were
obtained from binary mixtures made from five heavy oils and seven solvents, and
from six lower molar mass hydrocarbon-solvent mixtures.
The modified correlations were used to predi
