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
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
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
