Types of VLE diagrams

This program calculates the equilibral vapor pressure and corresponding temperature for some organic solvents or their binary/ternary mixtures.

If only 1 pure compound is selected, the vapor pressure will be plotted in function of temperature (p-T curve).

If 2 or 3 components are selected, you can choose either isobaric or isothermal circumstance and the program calculates and draws the corresponding binary x,y-T or x,y-p or x-y curves , or plots a triangle diagram with contour lines of temperature or pressure.




Note: the calculation/prediction can take a few minutes.

Tip: use the built-in unit converter by clicking on the blue unit labels in the form and the result table!
