Example 10-4

Transcribed Image Text:

A distillation column is separating n-hexane from n-heptane using 1-in. ceramic Intalox saddles. The allowable pressure drop in the column is 0.5 in. of water/ft. Average column pressure is 1.0 atm. Separation in the column is essentially complete, so the distillate is almost pure hexane, and the bottoms is almost pure heptane. The saturated liquid feed is 50.0 mol% n-hexane. L/V = 0.8. If F = 1000.0 lbmol/h and D = 500.0 lbmol/h, estimate the column diameter required at the top.
