Hydrogenation of nitrobenzene

Assignment Help Chemical Engineering
Reference no: EM13884192

Aniline is produced by the hydrogenation of nitrobenzene. The reaction takes place in a fluidized bed reactor operating at 270 °C and 20 bar. The excess heat of reaction is removed by a heat transfer fluid passing through tubes in the fluidized bed. Nitrobenzene vapor and hydrogen enter the reactor at a temperature of 260 °C. A typical reactor off-gas composition, mole percent, is: aniline 10.73, cyclohexylamine 0.11, water 21.68, nitrobenzene 0.45, hydrogen 63.67, inserts (take as nitrogen) 3.66. Estimate the heat removed by the heat transfer fluid, for a feed rate of nitrobenzene to the reactor of 2500 kg/h.
