Question
Transcribed Image Text:Write three balances and use one constraint for the performance of Still 2
to solve for the following quantities for a process feed (₁) of 300.0 mol/h.
Overhead from second still (n) = i
mol/h
Bottoms from second still (4) =
mol/h
Benzene mole fraction in bottoms from second still (X4B)
i
Toluene mole fraction in bottoms from second still (x4T) = i
Transcribed Image Text:A liquid mixture containing 30.0 mole% benzene
(B), 25.0% toluene (T), and the balance xylene (X)
is fed to a distillation column.
The bottoms product contains 98.0 mole% X and
no B, and 81.0% of the X in the feed is recovered in
this stream.
The overhead product is fed to a second column.
The overhead product from the second column
contains 95.5% of the B in the feed to this column.
The composition of this stream is 94.0 mole% B
and the balance T.
