In the production of ammonia (N₂ + 3H₂ → 2NH3), nitrogen and hydrogen are fed in stoichiometric proportion. The nitrogen feed contains 0.28% argon, which needs to be purged. The process is designed such that there is less than 0.25% of argon in the reactor. The reactor product is fed into a condenser where ammonia is separated from the unreacted hydrogen and nitrogen, which are recycled back to the reactor feed. The condenser is operating perfectly efficient. Calculate the amount of nitrogen and hydrogen that goes into the reactor per 200 kg of hydrogen fed into the process. Assume the single pass conversion of nitrogen is 10%.
