A continuous distillation column is to be used to separate a 3-component mixture of acetic acid (AA), water (W) and Benzene (B), and a trial run gave the data below (mass basis). The data for the benzene in the feed (which consists of AA, W and B) was not taken because of an instrument malfunction.
