Problem 1 A distillation column receives a feed that is 40 mol% n-pentane and 60 mol% n-hexane. Feed flow rate is 2500 lbmol/h, and feed temperature is 86F. The column is at 1 atm. A distillate that is 99.9 mol% n-pentane is desired. A total condenser is used. Reflux is a saturated liquid. The reflux ratio is L/D=3. Bottoms from the partial reboiler is 99.8 mol% n-hexane. Find D, B, q, and qc Thermodynamic data: n-Pentane boiling point Tocs = 95F ---Hexane boiling point 7.6 152.6F 11-Pentane latent heates 11369 Btu/Ibmol n-Hexane latent heat co = 13572 Btu/Ibmol - Pentane (1) heat capacity pcs(1) = 39.7 Btu/Ibmol F n-Hexane(1) heat capacity 0.6(l) = 51.7 Btu/Ibmol.F
