Example 15.7. The Ammonia Synthesis

Only a few short years ago, world leaders were predicting that the battle to feed humanity was over and that we could expect to undergo vast famines with hundreds of millions of people starving to death before the year 1985. 

Chemical engineering is at the heart of most otherfertilizers as well. 

One of the proudest accomplishments of the chemical engineering profession is the surge ahead in this round of the battle against the most constant enemy of humankind, 

Increased temperatures favor the rate of the reaction, but are not desirable from the conversion point of view. On the other hand, since v = -1, increased pressures favor conversion. Examine, thus, the effect of pressure on the equilibrium composition of ammonia, obtained from a stoichiometric mixture of H2 and N2 (3 1) at 450 C, where K = 7.739- 10- (Redlich). 

Repeat Example 15.6 using pure SO2 and O2 at their stoichiometric ratio at T = 600 C and F = 1 atm.
