Question 2 (25 Points) The vapor overhead of a distillation column is partially condensed and separated in a vertical flash drum at 5 bar and 50° C. Using Rachford-Rice method, calculate: a) (10 Points) The distillate flow rate and composition. b) (5 Points) The distillation column reflux ratio. c) kmol/h C 125 C₁ 25 C. 175 3 bat 50° C C3 C4 C3 28 1.3 0.4 (10 Points) The required flash drum diameter and height assuming residence time of 5 minutes and 50% liquid holdup. Assume the liquid stream has density, viscosity, and surface tension of 0.56 g/cm³, 0.15 cP, and 10.5 dyne/cm.
