Question

A continuous steady state distillation column is fed a mixture that is 70 mol% n-pentane and 30 mol% n-hexane. Feed rate is 1000 kmol/h. Feed is at 35 degrees celcius. Column is at 101.3 kpa. The vapor distillate product is 99.9 mol% n-pentane and the bottoms product is 99.9 mol% n-hexane. The system has a partial condenser (thus the distillate product is a saturated vapor) and operates at an external reflux ratio of L/D = 2.8. The reboiler is a partial reboiler. Find D, B, Qc, Qr Use DePriester chart to determine boiling points.
