A liquid mixture containing 30% mol benzene (B), 25.0% toluene (T), and the balance xylene (X) is fed to a distillation column. The bottoms product contains 98.0% mol X and no B, and 96% of the X in the feed is recovered in the stream. The overhead product is fed to a second column. The overhead product from the second column contains 97.0% of the B in the feed to this column. The composition of this stream is 94.0% mol B and the balance T. Calculate the percentage toluene in the process feed that emerges in the bottom product from the second column.
