VLE: Vapor-Liquid Equilibrium

You can specify the vapor-liquid equilibrium in two ways:
   1 - Relative volatility (alpha)
   2 - VLE data table.


You can work with azeotropes in binary mixtures.
See the VLE tables included with the application for:
    - Acetone - Chloroform
    - Ethanol - Water
    - Ethyl acetate - Ethanol
    - Etc...

3 ways to enter / modify values

The values can be modified in 3 ways:
1 - Moving the point with the mouse on the McCabe-Thiele diagram:
       We can change this way: Relative volatility, mole fractions of feed, distillate and bottoms,
       point q, parameter q, reflux ratio.
2 - Moving the graph cursor of the corresponding data.
3 - Writing its value.

Operational lines and q-line

Shows the enriching operating line, exhausting operating line, q-line and equations of each one.
We can move the q-point (point of intersection of these lines) on the McCabe-Thiele diagram.

Number of each theoretical tray

Shows the number of each theoretical tray in the McCabe-Thiele diagram.
