Just to retire this the question, the Ostwald process is the industrial process for nitric acid manufacture........

The Ostwald process is very much complementary to the Haber process for dinitrogen fixation, as it utilizes tonne quantities of ammonia.......

#4 NH_3(g) + 5O_2 (g) rarr 4NO(g) + 6H_2O(g) +Delta#

And once you got #NO#, this can be oxidized up to nitric acid...

#NO(g) + 1/2O_2(g) rarrNO_2(g)#

And finally...........

#3NO_2(g)+H_2O(l) rarr 2HNO_3(l) + NO(g) #

The nitrous oxide can be distilled off and recycled back into the former processes........
