Question
The reaction of hydrogenation of nitrobenzene to aniline can be represented by the following
equation:
A + B eC + D
The reaction is carried out adiabatically in a series of a staged packed-bed reactors with
interstage cooling. The lowest temperature to which the reactant stream may be cooled is
27 °C. The feed is equimolar in A and B and the catalyst weight in each reactor are sufficient
to achieve 99.9% of the equilibrium conversion. If the feed enters at 27 °C and four reactors
and three coolers are used as indicated in the Figure 2, evaluate the conversion to be achieved
from this reaction by plotting equilibrium conversion as a function of temperature.
