A flash separator “flashes” (abrupt increase in temperature and pressure) a liquid stream containing multiple species. Not all of the liquid vaporizes, but the vapor that does form is rich in one of the species, thereby separating it from the other. A liquid mixture of n-pentane and n-hexane containing 40mol% n-pentane is fed continuously to a flash separator operating at 121°C and 80 psia. Two streams, one liquid and one vapor, exit the separator and are in equilibrium with each other. The vapor is rich in which species, n-pentane or n-hexane? Calculate the composition of the vapor and liquid exit streams. Calculate the quantity of vapor and liquid produced per 100 moles of feed.

Question
A flash separator “flashes” (abrupt increase in temperature and pressure) a liquid stream containing multiple species. Not all of the liquid vaporizes, but the vapor that does form is rich in one of the species, thereby separating it from the other. A liquid mixture of n-pentane and n-hexane containing 40mol% n-pentane is fed continuously to a flash separator operating at 121°C and 80 psia. Two streams, one liquid and one vapor, exit the separator and are in equilibrium with each other.
The vapor is rich in which species, n-pentane or n-hexane?
Calculate the composition of the vapor and liquid exit streams.
Calculate the quantity of vapor and liquid produced per 100 moles of feed.
