Introduction
Let us see about nitric.The only important method is the Oswald process, which has rendered other methods. The first stage of the Ostwald process occupies the catalytic oxidation of ammonia to nitric oxide. Ammonia made by Haber process is mixed about ten times its volume of air and blown rapidly over the hot catalyst which consists of fine-mesh gauze of platinum-rhodium.
Nitric Acid
Nitric acid has 96%-98% of the ammonia is transformed into nitric oxide. The reaction is exothermic and continues the temperature at 900° C without external heating provided a heat exchanger is used.
The combination of gases is then cooled and weak with air, when the nitric oxide joins with oxygen to form nitrogen dioxide, which reacts with water giving nitric acid of about 50% focus. The second stage takes place in huge stainless steel inclusion towers designed to ensure systematic mixing of the ascending gases and the descending liquid. The treatment is sometimes agreed at a few times atmospheric pressure, when 60% acid if produced. Equations for the reactions happening in the second stage are:
2NO+O2 =2NO2
First: 2NO2+H2O=HNO3+HNO2
Then: 3HNO2=HNO3+2NO+H2O
Overall: 3NO2+H2O=2HNO3+NO
