A liquid feed (stream 1) containing 30 %(mol/mol) Benzene (B), 25 %(mol/mol) tolune (T) and the balance in xylene (X) is fed to a distillation column. The bottom product of unit 1 (stream 3) contains 98.0 %(mol/mol) of X and no B. It is also known that 96.0% of X in the feed is recovered in the bottom product of column 1. The overhead product of unit 1 (stream 2) is fed to unit 2. The overhead product of unit 2 (stream 4) contains 97 %(mol/mol) of the benzene in stream 2. The composition of stream 2 is 94.0 %(mol/mol) B, and the balance T. Basis of Calculation: 100 kmol h-1 of stream 1
Figure 2 shows a simplified block flow diagram of a distillation
process – you can assume ALL streams shown in the diagram
are liquid. A liquid feed (stream 1) containing 30 %(mol/mol)
Benzene (B), 25 %(mol/mol) tolune (T) and the balance in xylene
(X) is fed to a distillation column. The bottom product of unit 1
(stream 3) contains 98.0 %(mol/mol) of X and no B. It is also
known that 96.0% of X in the feed is recovered in the bottom
product of column 1. The overhead product of unit 1 (stream 2)
is fed to unit 2. The overhead product of unit 2 (stream 4)
contains 97 %(mol/mol) of the benzene in stream 2. The
composition of stream 2 is 94.0 %(mol/mol) B, and the
balance T.
Basis of Calculation: 100 kmol h-1 of stream 1.
