In the production of aniline by the hydrogenation of nitrobenzene, the reactor products are separated from unreacted hydrogen in a condenser. The condensate, which is mainly water and aniline, together with a small amount of unreacted nitrobenzene and cyclohexylamine, is fed to a decanter to separate the water and aniline. The separation will not be complete, as aniline is slightly soluble in water, and water in aniline. A typical material balance for the decanter is given below:
Basis 100 kg feed
Design a decanter for this duty, for a feed rate of 3500 kg/h. Concentrate on the separation of the water and aniline. The densities of water-aniline solutions are given in Appendix F, Problem F.8, available in the online material at booksite.Elsevier.com/Towler. The decanter will operate at a maximum temperature of 30 °C.
Design the manufacture of (tones/day) Ferrous sulphate monohydrate from waste pickle liquor. Pickling is generally associated with the removal of scale with mineral acid. Sulphuric acid is the most commonly used pickling acid.
Calculate the fraction of water that is condensed from the air, the relative humidity of the air at 100°C, and the ratio m3 outlet air at 100°C/m3 feed air at 90°C.
