drum d. If we want to obtain a liquid product that is 40 mol% acetone the feed, what must the mole fraction of the feed be? D18.* We wish to flash distill a feed that is 10 mol% propane, 30 mol% n-butane, and 60 mol% n-hexane. Feed rate is 10 kmol/h, and drum pressure is 200 kPa. We desire a and V/F. Con liquid that is 85 mol% n-hexane. Use De Priester charts. Find T a single tinue until your answer is within 0.5°C of the correct answer. Note: This trial and error, not a simultaneous mass and energy balance convergence problem. D19.* A flash drum operating at 300 kPa is separating a mixture that is fed in as 40 mol% isobutane, 25% n-pentane, and 35% n-hexane. We wish a 90% recovery of n-hexane in the liquid (that is, 90% of the n-hexane in the feed exits in the liquid product). F=1000 kmol/h. Find T D20. A flash drum operating at a pressure of 2.0 bar and a temperature of 0°C is separating a mixture of ethane (E), n-butane (B), and n-pentane (P). The fraction vaporized is VF = 0.25. The feed mole fraction of ethane is ze = 0.20. Find the mole fraction of n-butane, Zp, in the feed. Use the De Priester chart. D21. We wish to flash distill a feed that is 55 mol% ethane and 45 mol% n-pentane. The = 700 kPa and T = 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 hotal/ D = 4. drum *;, Y; VE drum operates Pdrum drum MW ethane = 30.07, MW pentane = 72.15 Liquid densitites: PE = 0.54 g/ml (estimated), Pp = 0.63 g/ml D22. A flash drum is separating a feed that is 50 wt % n-propanol and 50 wt% isopropanol with F=100 kmol/h. T. = 90°C and n 1012 IR
