We wish to flash distill a feed that is 55 mol% ethane and 45 mol% n-pentane. the drum operates pdrum - 700 kpa and tdrum - 30°c. feed flow rate is 100,000 kg/h. a. find v/f, v, l, liquid mole fraction, vapor mole fraction. b. find the dimensions in metric units required for a vertical flash drum. assume the vapor is an ideal gas to calculate vapor densities. use de priester chart for vle. be careful of units. arbitrarily pick htotal/d - 4. mwethane - 30.07, mw pentane - 72.15 liquid densitites: pe -0.54 g/ml (estimated), pp -0.63 g/ml
