Question

Design criteria are the desired features of a design. Identify at least two criteria for the design of the ammonia-making process. Explain why these criteria are important.

Answer 1

Answer:

The ammonia production design process has two design requirements;

1. Sustainable renewable energy production of hydrogen.
2. Sustainable use of another thermal ammonia-water process to retrieve ammonia throughout the wastewater.

Explanation:

In the following process, ammonia is provided by natural gas:

$H_2 + RSH \to RH + H_2S\\\\H_2S + ZnO \to ZnS + H_2O \ \ (Waste \ water)\\\\CH_4 + H_2O \to CO + 3H_2\\\\CO + H_2O \to CO_2 + H_2$

Ammonia would then be generated in a process called also as Haber-Bosch process by responding to produced hydrogen to nitrogen throughout the presence of catalysts.

$3H_2 + N_2 \to 2NH_3$

Answer 2

Answer:

Sustainable renewable energy production of hydrogen.

Sustainable use of another thermal ammonia-water process to retrieve ammonia throughout the wastewater.
