PREPRATION OF NITRIC ACID
METHOD OF PRODUCTION Ammonia Oxidation process Accounts for 90% production process is devided into four fundamental steps oxidation of NH3 to NO oxidation of NO to NO2 absorption of NO2 in water concentration of HNO3 CHEMICAL REACTION Oxidation of ammonia NH3 + 5/4 O2 = NO + 3/4 H2O H= - 54.0 Kcal NO2 + O2 = 2NO2 H= - 27.2 Kcal Nitrous oxide oxidation and absorption 2NO + O2 = 2NO2 ...
