correction: xB = 0.05

A distillation column is fed with 700 mol/s C5H12 and C6H14 mixture in which its feed ratio is 0.5. The feed exactly enters the feed tray at its bubbling point. It is desired to produce a product whose composition is x8=0.5 and xD=0.98 with = 2.25. The tray temperature is the same as the feed temperature and the column pressure is at 1 bar while the vapor pressure of the more volatile component is given by 11 T - 3410 In P= T where P is in bar and T is in K The vapor pressure of the other component is 1/3 of the vapor pressure of the more volatile component. Determine = = a. The vapor stream from the reboiler b. The energy required in the reboiler if Qreb = Hvap V" and Hyap = 30 kJ/s C. The number of stages graphically and d. The height of the column if the distance between trays is 0.5 m. Hmin = Hspacing (N 1)
