8. Ammonia is widely used in products such as fertilisers and household cleaning agents.

(b) Determine molar flow rate in Ibmol/month of hydrogen needed by Ahmolia Co. Assume there is an average of 30 days per month. The iron catalyst gets fouled over time, which results in a reduction in reaction efficiency of the Haber process. As such, only 65% of the hydrogen calculated in part (b) reacts to form ammonia. (c) Determine mass in ton of ammonia produced annually as a result of the reduction in reaction efficiency.

Question
8. Ammonia is widely used in products such as fertilisers and household cleaning
agents. Synthesis of ammonia is via the Haber process whereby nitrogen and
hydrogen are enriched over an iron catalyst.
N2(g) + 3H2(g) –→ 2NH3(g)
Ahmolia Co. is a local company that produces 250 lbm of ammonia daily via the
Haber process.
(a) Determine mass flow rate in kg/day of nitrogen needed by Ahmolia Co.
(b) Determine molar flow rate in Ibmol/month of hydrogen needed by Ahmolia Co.
Assume there is an average of 30 days per month.
The iron catalyst gets fouled over time, which results in a reduction in reaction
efficiency of the Haber process. As such, only 65% of the hydrogen calculated in
part (b) reacts to form ammonia.
(c) Determine mass in ton of ammonia produced annually as a result of the
reduction in reaction efficiency.
