A mixture of 100 mol containing 60 mol% n-pentane and 40 mol% n-heptane is vaporized at 101.325 kPa abs pressure until 40 mol of vapor and 60 mol of liquid in equilibrium with each other are produced. This occurs in a single-stage system and the vapor and liquid are kept in contact with each other until the vaporization is complete. Calculate the composition of the vapor and liquid. The equilibrium data are as follows, where x and y aremole fractions of n-pentane.

A 100 mol/h feed mixture with 10% pentane, 10% hexane, 30% heptane and 50% octane is to be distilled in a single column to give an overall distillate product that contains no more than 6 mol/h of heptane and a bottoms product that contains a maximum of 3 mol/h of hexane. Calculate the distillate and bottoms mole fractions XDi and XBi,for all other components.

A liquid mixture of n-hexane and n-heptane is to be flashed. How much energy per second is required to heat 1 mol/s of a mixture of 75 mol% n-hexane and 25 mol% n-heptane from 25ºC to 75ºC at 1 atm pressure (with vapor and liquid product streams leaving at 75ºC at equilibrium)? Also find the vapor and liquid product flowrates and compositions.
