Transport Properties of Petroleum Fractions

A corresponding-states model for the transport properties of petroleum fractions is preseInted. The model requires only the API specific gravity and the mean average boiling point as input parameters. The extended correspanding-states model uses propane as a reference fluid, and new generalized shape factor expressions that are functions of the acentric factor and the reduced temperature are preseInted. Also preseInted are new correlating functions for the viscosity and thermal conductivity of the reference fluid that can be extrapolated well below the freezing point of propane. The performance of the model is demonstrated by comparing with experimental data for viscosity and thermal conductivity of petroleum fractions.
