Make an engineering flowchart! With boxes for reactors anf arrows Part B$.$ Design a process to produce a $HN{O}_3+H_{2}O$ solution from methane, water, and air. That is$,$ design a process to produce ammonia, and then use the ammonia to produce nitric acid. Do not simply copy the ammonia process developed in Chapter $2.$ The ammonia process can be improved when integrated with the nitric acid synthesis. Specifically, you can avoid the costly cryogenic separation of $N_2$ and $O_2.$ Hint: Use excess $N{H}_3$ in the feed to the nitric acid reactor in part $($B$).($Excess $N{H}_3$ is not necessarily best for part $($A$).)$

Recall ammonia is synthesized by the following reaction at $500$ :

$N_2+3H_{2}Fe2N{H}_3.$

The conversion to ammonia is less than $100\%$ : the effluent will contain $N_2$ and $H_2.$ Generate $H_2$ by the method used in Chapter $2$ for the fuel cell. You may assume methane can be "burned" in water in one step at $450C$ :

$C{H}_4+2H_{2}OcatalystXC{O}_2+4H_2.$

Furthermore, you may assume excess $H_{2}O$ will consume all the $C{H}_4.$ Below is a summary of substances required, tolerated, and forbidden in the three reactors:
