Syngas in stoichiometric proportions (1:3 N2:H2) is fed to the system.

See Fig. P5.3 for the scheme of the synthesis loop. It also contains Ar, 0.2 moles per 100 moles of mixture (N213H2). Assuming the following, determine the purge of the system:

1. The reactor conversion is 25%.

2. Only 75% of the ammonia produced is recovered.

3. The converter can only handle Ar at 2.43 moles per 100 moles of syngas mixture.
