180 kmol h-1 of a three component mixture is made up of 60 mol % 'A', 25 mol % 'B' and 15 mol % 'C'.
Component 'A' is the most volatile and 'C' the least volatile. The mixture is to be separated by continuous distillation in two columns so that 80% of 'C' in the feed is removed as bottom product in the first column as a 90 mol % solution with B.
The top product from the first column will be separated in the second column to give a top product here of 95 mol % 'A' and a bottom product of 85 mol % 'B'.
Determine the flows from the two columns and the mol % 'A' in bottom product from column 2.
(Assume there is to be no 'A' in the bottom product of column 1 and no 'C' in the top product of column 2.)
