Free benzene from a scrubber's coal gas is recovered by passing
a solution of benzene and scrubbing oil through a tower in contact
with the steam. The entering liquid stream contains 8 mol% benzene.
It is desired to recover 80% of the benzene using a vapor ratio
that is 1.4 times the minimum ratio. An expense in the washing oil
(benzene-free liquid solvent) of 6.94 mol/s will be used.
determine the required moles of steam per second if
a) a parallel draft tower is used
b) a tower downstream
The equilibrium data for the benzene washed oil vapor system is as
follows:
do the analysis in both insisos of the
tower
