Question
A distillation column is separating Benzene and Phenol (average relative volatility is 2.5) which operates at atmospheric pressure. Two different feed enters to the column at rate of 1,600 kmol/hr with 35% Phenol and 80% liquid; and the second feed enters containing 45% benzene at rate of 1,800 kmol/hr. Feed 2 contains 85% liquid. The distillate and bottom composition of Benzene are required to be 92 mole% and 8 mole% respectively. The reflux ratio is 1.9 times the minimum value. Calculate:i.On graph paperdraw and label the VLE curve including x=y line.ii.Mass balance around the column. iii.The location of the feed plates. iv.Minimum reflux ratio. v.Minimum and the ideal number of plates.
