A vertical flash drum is designed with a m, lbm/hr feed consisting of n-hexane and n-octane. The mass fraction of n-hexane in the feed stream is mf. The vertical flash drum will operate at T OF and P atm. Use the McWilliams equations shown in Equation 2-30 and Table 2-3 for K values. m, lbm/hr mf, mass fraction of n- hexane in the feed stream T, F P, atm Be 109,000 0.247 273 2.07 1. Sketch the problem according to the problem description. 2. Find the mole fractions of the liquid phase and the vapor phase, and V/F, using the Rachford Rice equation, as shown below (equation 2-41 in our textbook).
