A separation stream off the main reactor effluent
contains almost exclusively ethyl benzene,
benzene, and toluene at 1 bar and 100°C. You determine
that the stream flow rate is made up of
34 kg/s of benzene, 10 kg/s of toluene, and 57.75
kg/s of the other component. You send this mixture
into a flash distillation unit operating at 0.6
bar and 100°C.
A. Estimate if this mixture flashes.
B. If the mixture flashes, determine the composition
and amount of the equilibrium liquid and
vapor.
C. You send the liquid exiting the flash distillation
unit into another flash distillation unit
operating at 1.5 bar and 140°C. Determine
if this mixture flashes. If so, determine the
composition and amounts of the equilibrium
phases.
D. What percentage of the original benzene that
left the reactor is now a vapor (you have to consider
both flash units).
