    Phase envelope

    fortunately in this project I have a very low (negligible) amount of water, with water I use the mixing rule by Kabadi and Danner which is avaiable in our simulator but usually I have no feedback confirming the accuracy, the point is that there is not much time for testing the real consistency...

    Phase envelope

    Paolo, I didn't suppose that the addition of 6% H2S could generate that complex behaviour, I found several papers of Michelsen discussing phase equilibria with several examples and many of these examples do include H2S, a interesting reading, Alfonso

    Phase envelope

    I am getting strange results when printing a phase envelope of a natural gas mixture from our simulator (package Peng Robinson), when I add 6% H2S to a C1 60% C2 11% C3 C4 C6 C8 N2 CO2 the dew and bubble lines don't connect but go up and down in a strange fashion, also I am not able to get the...
