Problem 1. A feed consisting of n-butane. n-pentane, and n-hexane is fed at a rate of m kg/min to a flash drum operated at TC and P kPa. Find the molar rate of a feed in kg-mole/hr, the molar rate of a vapor-phase in kg. mole/hr, the molar rate of a liquid-phase in kg-mole/hr, V/F, and mole fractions of the liquid phase, and mole fractions of the vapor phase. Use the McWilliams equations shown in Equation 2-30 and Table 2-3. Table. Operating conditions of a flash drum Feed Composition, w% Name , kg/min T.
