Feed gas containing of 78.5mol2H2,21% of N2&0.5% of Ar is mixed with recycle gas and enters a reactor where 15%N2 is converted to NH3 as per the reaction. Ammonia from the exit of the reactor is completely separated from unconverted gases. To avoid the buildup of inerts, a small fraction (5%) of the unreacted gases purged and the balance recycled.
