mass transfer

The column separating has Component (B), Component (T), and Component (C). The column has a total condenser and a partial reboiler and has 18 equilibrium stages. The feed is 25 mol% (B), 30 mol% (T), and 45 mol% (C). Feed rate is 100 kmol/h and feed is a saturated liquid. The equilibrium data can be represented as constant relative volatilities Xac-5, Xyc = 2.5, and occ= 1.0. We desire 99% recovery of (T) in the distillate and 98% recovery of (C) in the bottoms. a) Determine the composition and amounts of distillate and bottoms b) Minimum number of stages Nmin and minimum reflux Rmin. c) Determine the external reflux ratio R
