Ponchon-Savarit Diagram for Methanol-Water Mixture

​
Ponchon-Savarit diagram
pressure in mmHg
760
This Demonstration shows plots of the Ponchon–Savarit diagram (i.e.,
H
V
(y)
and
h
l
(x)
) for a methanol-water mixture at user-set values of the total pressure,
P
. In addition, the tie lines or isotherms are shown in green. The data obtained in our simulation, for
P=760mmHg
, agrees very well with those given in Henley and Seader's classic textbook[1], which are shown by red dots. The vapor-liquid equilibrium data is also plotted in a separate diagram.
