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.
