Aliquid mixture containing 40 wt% benzene (B), 25 wt% toluene (T) and the balnce Xylene (X) is fed at a rate of 100 Kg/min to a distillation unit consisting of two columns. The bottoms product from the first column is to contain 97 wt% X and no B, and 94 wt% of the X in the feed is to be recovered in the stream. The overhead product from the first column is fed to a second column. The overhead product from the second column contains 97 wt% B and no X. The benzene recovered in this stream represents 96 wt% of the B in the feed to this column. Calculate the molar flow rates (Kg/min) and component m ass fractions in each product stream both columns.
