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 thebubbling point, enters the column exactly on the feed tray. The tray temperature is equal tothe 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 thetrays amounts to 0.50 m. A.Calculate the vapor stream from the reboiler B.Calculate the required energy in the reboiler

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 thebubbling point, enters the column exactly on the feed tray. The tray temperature is equal tothe 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 thetrays amounts to 0.50 m.
A.Calculate the vapor stream from the reboiler
B.Calculate the required energy in the reboiler
