A fresh feed stream containing 4.0 mol% inert gas and a  stoichiometric ratio of hydrogen and nitrogen is combined with a recycle stream  and is fed to a system to produce ammonia according to the reaction:

 

N₂ + 3H₂ = 2NH₃

The single pass conversion in the reactor is 20 % (moles N₂  reacted per mole of N₂ fed to the reactor).  The gas leaving the reactor goes to a  condenser where all the ammonia is recovered.   Ten (10) percent of the unreacted gas stream is purged from the system,  and the remainder is recycled, mixed with fresh feed and fed to the  reactor.  Calculate:

The  overall conversion of fresh N₂.

The moles recycled per mole of fresh feed  

Answer rating: 100% (QA)

To solve this problem we will first calculate the overall conversion of fresh N2 and then determine ... View the full answer
