Light Hydrocarbon Thermodynamic Properties

This page is designed to allow users to select a pure component or a mixture of components and determine the vapor-liquid split (if two-phase), the liquid and vapor densities, enthalpies, heat capacities, and compositions at an input temperature and pressure. It then performs an adiabatic flash calculation from the input pressure to one atmosphere and displays the final properties. This page is currently using the Peng-Robinson equation of state to predict the properties of these mixtures. To try it out, create an input mixture using the form below and hit the done button to start the calculations.

Initial Conditions

Input the initial temperature and pressure:

  • Temperature: K
  • Pressure: kPa

Mixture

Select the components for your mixture from the lists below and enter the mole fraction of each component in the field to the right. If the mole fractions do not sum to one when you are done, they will be re-normalized for you.
