A process consists of two distillation columns. The composition of the feed to the first tower is 30.0 mol% benzene (B), 30.0 mol% tolu- ene (T), and 40.0 mol% xylene (X). The overhead stream from the first tower contains no xylene (X). The benzene content of the overhead stream from the first tower is 55.0 mol%. The bottoms stream from the second tower has a flow rate of 100 mol/h and contains 15.0 mol% toluene and no benzene. While the overhead stream from the second tower contains 50.0 mol% benzene, there are also other components, T or X, or both, in this stream. The flow rate of the overhead stream from the first tower is twice the flow rate of the overhead stream from the second tower. Determine the molar flow rates of the fresh feed stream, the overhead stream leaving the first column and the mole fractions in the overhead stream in the second column.

Transcribed Image Text:A process consists of two distillation columns. The composition of
the feed to the first tower is 30.0 mol% benzene (B), 30.0 mol% tolu-
ene (T), and 40.0 mol% xylene (X). The overhead stream from the first
tower contains no xylene (X). The benzene content of the overhead
stream from the first tower is 55.0 mol%. The bottoms stream from
the second tower has a flow rate of 100 mol/h and contains 15.0 mol%
toluene and no benzene. While the overhead stream from the second
tower contains 50.0 mol% benzene, there are also other components,
T or X, or both, in this stream. The flow rate of the overhead stream
from the first tower is twice the flow rate of the overhead stream from
the second tower. Determine the molar flow rates of the fresh feed
stream, the overhead stream leaving the first column and the mole fractions in the overhead stream in the
second column.
