PetroFrac app analytics for September 1

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 gravity Watson K MW, molecular weight Once you enter the flow temperature the program calculates: Density at flow temperature, g/cm3 Viscosity at flow temperature, cSt Cp, Heat capacity at flow temperature, BTU/(lb Deg F) H Liquid, Enthalpy of liquid at flow temperature, BTU/Deg F H Vapor, Enthalpy of vapor at flow temperature, BTU/Deg F Heat Vap, Heat of vaporization at flow temperature, BTU/Deg F Any values that are extrapolated beyond the ranges of the correlations are displayed in purple text. 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. Fahim Fuel 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.
