Hydrogen estimation

In the manufacture of aniline, liquid nitrobenzene at 20 °C is fed to a vaporiser where it is vaporised in a stream of hydrogen. The hydrogen stream is at 30 °C, and the vaporiser operates at 20 bar. For feed-rates of 2500 kg/h nitrobenzene and 366 kg/h hydrogen, estimate the heat input required. The nitrobenzene vapour is not superheated.

The difficulties associated with making an atomic-hydrogen target have precluded direct measurements of total cross sections for hydrogen. Estimates may be made by adding the best available estimates for the integrated cross sections of particular channels and the total ionisation cross section. 

Technically, it is far simpler to remove the CO2 from either natural gas reformation or coal gasification as the carbon already is being separated from the hydrogen. Estimates of the technically recoverable CO2 range from 87% (Williams 2001) to 92% (NAE 2004). Williams...
