Aniline is produced by the hydrogenation of nitrobenzene. A small amount of cyclo-hexylamine is produced as a byproduct. The reactions are:
1. C6H5NO2 + 3H2 C6H5NH2 + 2H2O
2. C6H5NO2 + 6H2 C6H11NH2 + 2H2O
Nitrobenzene is fed to the reactor as a vapour, with three times the stoichiometric quantity of hydrogen. The conversion of the nitrobenzene to all products is 96% and the yield to aniline is 95%. The unreacted hydrogen is separated from the reactor products and recycled to the reactor. A purge is taken from the recycle stream to maintain the inerts in the recycle stream below 5%. The fresh hydrogen feed is 99.5% pure and the remainder being inerts. All percentages are molar. For a feed rate of 100kmol/h of nitrobenzene, calculate:
a) The fresh hydrogen feed
b) The purge rate required
c) The composition of the reactor outlet stream.
