Asynthetic ammonia plant is continuously fed with a 1: 3 molar nitrogen-hydrogen mixture containing 0.4 moles of argon per 100 moles of nitrogen-hydrogen mixture. the conversion in the reactor is 30% and the level of argon in the reactor outlet is 5%, by volume, of the sum of the hydrogen and nitrogen at the reactor outlet. the reactor outlet stream is cooled in a condenser. assume all the ammonia leaves from the condenser as liquid and this product stream is 100% pure. the vapour stream leaving the condenser is recycled. (a) draw the flow diagram of the process. [3 marks) (b) write the chemical equation for the ammonia formation reaction and state whether any of the reactants are in excess. [1 mark] explain why the mole ratio of argon to the mixture of hydrogen and nitrogen is the same before and after the condenser [1 mark] calculate the amount of the purge for a given feed rate of the mixture of hydrogen and nitrogen. [4 marks] calculate the fraction of the unreacted nitrogen and hydrogen from the condenser, which is continuously purged, to maintain the argon level. [6 marks] calculate the feed rate (in tonnes per hour) needed to produce 1 tonne per hour of ammonia. [5 marks] the atomic weight of argon is 40.
