The fresh feed to an ammonia production process contains nitrogen and 75% excess hydrogen in stoichiometric proportion, along with an 1.0 mole % inert gas (I). The feed is combined with a recycle stream containing the same three species, and the combined stream is fed to a reactor in which a 47% single-pass conversion of nitrogen is achieved. The reactor effluent flows to a condenser. A liquid stream containing essentially all the ammonia formed in the reactor while gas stream (75 mol/h) containing inert and the unreacted nitrogen and hydrogen leave the condenser. the gas stream is split into two fractions with the same composition: one is removed from the process as a purge stream (10% from the total gas stream), and the other is the recycle stream combined with fresh feed.
1) for a basis of 100 mol/h, calculate the mol fraction of nitrogen and hydrogen at fresh feed stream
2) Determine the flowrate (mol/h) for recycle and purge stream
3) Determine the flowrate (mol/h) for combined stream (reactor inlet stream) and the composition for all species in that stream
4) Determine the flowrate (mol/h) for each species in the reactor outlet stream. nest calculate the production rate of ammonia leaving the condenser
5) Determine the extent of reaction in the reactor.
6) Determine the overall conversion of nitrogen for the above system.
