PetroFrac calculates properties of refinery petroleum fractions based on the D86 distillation and API gravity. You enter the 10%, 50% and 90% D86 distillation temperatures along with the API gravity.The program calculates:SG, Specific gravityWatson KMW, molecular weightOnce you enter the flow temperature the program calculates:Density at flow temperature, g/cm3Viscosity at flow temperature, cStCp, Heat capacity at flow temperature, BTU/(lb Deg F)H Liquid, Enthalpy of liquid at flow temperature, BTU/Deg FH Vapor, Enthalpy of vapor at flow temperature, BTU/Deg FHeat Vap, Heat of vaporization at flow temperature, BTU/Deg FAny values that are extrapolated beyond the ranges of the correlations are displayed in purple text.Tapping on the API label toggles it to specific gravity so you can enter it instead of API. PetroFrac then calculates the API gravity.The calculations are based on:“New correlation for predicting the viscosity of heavy petroleum fractions”H. M. Moharam, R. A. Al-Mehaideb and M. A. FahimFuel vol. 74, 1995. I have extended the correlation range using ASTM Designation: D341 – 93 (Reapproved 1998).“New correlation predicts density of petroleum fractions”Jose Vicente Gomez, Oil and Gas Journal, July 13, 1992“Improve Predicted Enthalpy of Fractions”M.
