This is a brief question that will aid me in my design project and it is regarding generating H-xy, enthalpy concentration, diagrams to use in the Ponchon-Savarit method. 

 

I am able to generate T-xy, P-xy and yx diagrams using Aspen Plus binary analysis feature, however there isn't an option listed for plotting enthalpy concentration. I have seen previously tha people have generated them through using Aspen HYSYS and SimSci PRO/II, however I am unfamiliar with the latter.

 

Is there a way of plotting these graphs, or is there a guide?

I have a different software (Prode Properties) , to generate a enthalpy concentration plot in Excel I start solving a series of points on specified equilibrium lines, then I can calculate enthalpy or entropy or volume or....

Is there a guide I can use to do this?

yes, you can start for example from tpxy.xls Excel page included in distribution and add the properties which you need,

of course you can follow a equivalent methodology with another software...
