The feedstock for the production of ammonia contains 0.5 mol of Ar per 100 mol of N2H2 mixture. After mixing it with the recycle, the stream is fed to the converter. The syngas has stoichiometric proportions of nitrogen and hydrogen (N213H2). The gas also contains 5 moles of Ar per 100 moles of syngas. The reactor is operated at 200 atm and 740K isothermally where the equilibrium shown below takes place:

0:5N2 11:5H2’-NH3 The equilibrium constant (Kp) can be computed as a function of the temperature using the following equation:

A fraction of the recycle stream is purged. Determine the flow of each stream (1, 2, 3, and 4) in Fig. P5.3 per 100 moles of syngas fed to the system. 2 3 NH
