Calculation of Natural Gas Phase Diagram

Calculation of Natural Gas Phase Diagram

Calculation of Natural Gas Phase Diagram

I always use Hysys to calculate Natural Gas Phase Diagram  using Peng Robinson property package.
I would like to know how this software caluclates this diagram. I assume that it applies Peng Robinson equation but I can´t figure how it gets the equilibrium points.

RE: Calculation of Natural Gas Phase Diagram

You have to be more clear than that - are you asking how it finds the dewpoint/bubl points - or why it chooses exactly the values that it chooses (e.g. why dosnt it use a equal P or T step)?

Best regards


RE: Calculation of Natural Gas Phase Diagram

Hi MortenA, thanks for answering.
What I want to know is how it finds the dewpoint/buble points. Which equations, data and methods this software uses to calculate this diagram.
