1) a

b)

answer both...

If the overhead product in a distillation column (D) = 50 Kgmol/h. what is the vapor flow rate in the rectifying section when the feed (F) is saturated liquid with flow rate of 100 kgmol/h and the reflux ratio (RD)=3.5 225 150 175 100 1 0.9 Feed line 0.8 0.7 ROL 0.6 0.5 S.O.L 0.4 0.3 0.2 0.1 0 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1 From the above figure, if the feed to the distillation column (F) is 100 kmol/h, calculate the overhead product (D) and the bottoms (B)
