Prediction of the viscosity of liquid petroleum products

Abstract

The article deals with the new technique for predicting the viscosity of liquid petroleum products, which differ significantly in physicochemical properties and fractional composition, in a wide range of state parameters. No specific information is used to predict viscosity other than molar mass, average volume boiling point, and relative density at 20 °C. It is shown that the deviation of the predicted values from the experimental data is comparable to the error of the viscosity measurement. Methods for correcting the calculation results using limited experimental information are proposed. The application of the developed method is advisable in conditions of a lack of empirical information about the petroleum products viscosity.
