The fresh feed to an ammonia process contains 24.75% mole Nitrogen, 74.25% mole Hydrogen, and the balance inerts. The feed is combined with a recycle stream containing the same species, and the combined stream is fed to a reactor in which a 25% single-pass conversion of nitrogen is achieved. The products pass through a condenser in which essentially all of the ammonia is removed, and the remaining gases are recycled. However, to prevent buildup of the inerts in the system, a purge stream must be taken off. The recycle stream contains 12.5% mole inerts. Calculate the overall conversion of nitrogen, the ration (moles purge gas / mole of as leaving the condenser), and the ratio (moles fresh feed / mole fed to the reactor).

The fresh feed to an ammonia process contains 24.75% mole Nitrogen, 74.25% mole Hydrogen, and the balance inerts. The feed is combined with a recycle stream containing the same species, and the combined stream is fed to a reactor in which a 25% single-pass conversion of nitrogen is achieved. The products pass through a condenser in which essentially all of the ammonia is removed, and the remaining gases are recycled. However, to prevent buildup of the inerts in the system, a purge stream must be taken off. The recycle stream contains 12.5% mole inerts. Calculate the overall conversion of nitrogen, the ration (moles purge gas / mole of as leaving the condenser), and the ratio (moles fresh feed/ mole fed to the reactor).
