A distillation column is separating n-hexane from n-heptane using 1-inch ceramic Intalox saddles. The allowable pressure drop in the column is 0.5 inches of water per foot. Average column pressure is 1 atm. Separation in the column is essentially complete, so the distillate is almost pure hexane and the bottoms is almost pure heptane. Feed is a 50-50 mixture and is a saturated liquid. In the top, L/V = 0.8. If F = 1000 lbmol/h and D = 500 lbmol/h, estimate the column diameter required at the bottom of the column. Use physical property data from Example 10-4.
