Enthalpy versus Composition Diagram for n-Hexane/n-Octane at 101 kPa

Consider a binary mixture composed of

n

-hexane and

n

-octane; this Demonstration uses Henley and Seader's data to plot the enthalpy versus composition diagram at 101 kPa. The curves are the liquid (

Hl

, in blue) and vapor (

Hv

, in magenta) enthalpy versus the liquid (

x

) and vapor (

y

) mole fraction curves. Click either curve to place the locator there. Then the vapor-liquid and enthalpy data is displayed as text at the bottom and the tie line is plotted in red.
