Answer:
Two design criteria for the design of the ammonia making process are;
1) Sustainable hydrogen production by renewable energy
2) Sustainable use of the ammonia-water thermal absorption cycle to retrieve the ammonia present in the waster water
Explanation:
Ammonia is produced from natural gas in the following process;
H₂ + RSH → RH + H₂S
H₂S + ZnO → ZnS + H₂O (Waste water)
CH₄ + H₂O → CO + 3H₂
CO + H₂O → CO₂ + H₂
Ammonia is then produced by reacting the produced hydrogen with nitrogen in the presence of a catalyst in a process known as the Haber-Bosch process as follows;
3H₂ + N₂ → 2NH₃
The
The design criteria for the design of the ammonia making process therefore as follows;
1) Sustainable use of renewable energy to produce hydrogen gas from the electrolysis of water
2) Use of the ammonia-water thermal absorption cycle to retrieve the ammonia present in the waster water.
(1) Divide the equation into two half-reactions. (2) Balance each half-reaction for mass and charge. (3) Equalize the number of electrons transferred in each half-reaction. (4) Add the half-reactions together.l
