Abstract

Generalized equation predicts viscosity of heavy oil-solvent mixtures A. Miadonye and A.J. Britten Department of Physical and Applied Sciences, University College of Cape Breton. Sydney, Nova Scotia. Canada. 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
