A liquid mixture containing 31.4 mol% benzene, 29.7 mol% toluene, and the balance xylene is fed to a distillation column. The bottom product contains 95.6 mol% xylene and no benzene, and 96.4% of the xylene in the feed is recovered in this stream. The overhead product is fed to a second distillation column. The overhead product from the second column contains 97% of the benzene in THE FEED TO THIS COLUMN. The composition of this stream is 94 mole% benzene and the balance toluene. For a feed flow rate of 110 kmol/h, calculate: a. the amount of overhead product from the first column b. the concentration of xylene in the overhead product from the first column the amount overhead product from the second column с. d. the percent of toluene from the feed that emerges in the bottoms product Overhead 2 Overhead 1 Feed Column 1 Column 2 Bottoms 1 Bottoms 2

Question
Transcribed Image Text:A liquid mixture containing 31.4 mol% benzene, 29.7 mol% toluene, and the balance
xylene is fed to a distillation column. The bottom product contains 95.6 mol% xylene
and no benzene, and 96.4% of the xylene in the feed is recovered in this stream. The
overhead product is fed to a second distillation column. The overhead product from the
second column contains 97% of the benzene in THE FEED TO THIS COLUMN. The
composition of this stream is 94 mole% benzene and the balance toluene. For a feed
flow rate of 110 kmol/h, calculate:
a.
the amount of overhead product from the first column
b.
the concentration of xylene in the overhead product from the first column
the amount overhead product from the second column
с.
d. the percent of toluene from the feed that emerges in the bottoms product
