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 Table. Operating conditions of a flash drum Feed Composition, w% Name T." butane PKP m, kg/min pentane hexane n- n- - 32 35 33 3.494.90 48 13
