Flash Vaporization of a Heptane-Octane Mixture

​
vapor fraction
0.2
Consider an ideal binary mixture composed of
n
-heptane and
n
-octane. The feed to a flash drum is composed of 50% mole of
n
-heptane at a temperature equal to 303 K. This feed is flash vaporized at
P=1atm
. When you set the desired vapor fraction, the Demonstration computes the vapor and liquid compositions as well as the temperature in the separator. The heat added is also calculated.
