Q2: A liquid mixture containing 30% Benzene (B), 25% Toluene (T) and 45% Xylene (X) is fed at a rate of 1275 kg/hr to the first column of a distillation unit consisting of two columns. The bottom stream of the first column contains B and X only (99% X and 1% B) in which 98% of the amount of X in the feed is to be recovered in this stream. The overhead product from this column which contains B, T and X is fed to the second column. The overhead stream of the second column contains 99% B and 1% X and the amount of B recovered in this stream is 96% of its amount in the feed of this column. Calculate the flow rate and the composition of all streams.
