    Hi,

    I would like to calculate an vlle azeotrope composition and temperature from a mixture with dwsim.
    Any idea how could I achieve this with DWSIM current build?

    Thanks

    Hi,

    First if our mixture is known, you may have a look to the dortmund database
    http://www.ddbst.com/en/EED/AZD/AZDindex.php
    By using DWSIM, to predict vle equilibrium of a binary, once your stream is defined, select it and go to "Utilities>Binary envelope". Select compounds 1 and 2, envelope "Txy", enter the pressure and click on calculate. What I often do is "compare model". Your azeotrope can be found when Tbubble=Tdew

    Hope it will hep you
