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 submit button to start the calculations.

Initial Conditions
