Distillation is used to separate pentane from hexane. The feed amounts 700 mol/s and has amole ratio pentane/hexane = 0.5. The bottom and top products have the compositions xB=0.05 andxD= 0.98. The reflux ratio is 2.25. The column pressure is 1 bar. The feed, at the bubbling point, enters the column exactly on the feed tray. The tray temperature is equal to the feed temperature. The pentane vapor pressure is given by: lnP=11T-3410/T The vapor pressure of hexane is 1/3 of the pentane vapor pressure over the whole temperature range. The heat of vaporization amounts to 30 kJ/mol. The distance between the trays amounts to 0.50 m. A.The vapor stream from the reboiler=693.100 mole/s B.The required energy in the reboiler=20793.01887 kJ/s c. number of equilibrium stages

Question
Distillation is used to separate pentane from hexane. The feed amounts 700 mol/s and has amole ratio pentane/hexane = 0.5. The bottom and top products have the compositions xB=0.05 andxD= 0.98. The reflux ratio is 2.25. The column pressure is 1 bar. The feed, at the bubbling point, enters the column exactly on the feed tray. The tray temperature is equal to the feed temperature. The pentane vapor pressure is given by:
lnP=11T-3410/T
The vapor pressure of hexane is 1/3 of the pentane vapor pressure over the whole temperature range. The heat of vaporization amounts to 30 kJ/mol. The distance between the trays amounts to 0.50 m.
A.The vapor stream from the reboiler=693.100 mole/s
B.The required energy in the reboiler=20793.01887 kJ/s
c. number of equilibrium stages
d.height of column
