Процесс производства разбавленной азотной кислоты складывается из трех стадий:
1) конверсии аммиака с целью получения оксида азота
4NH3 + 5О2 → 4NO + 6Н2О
2) окисления оксида азота до диоксида азота
2NO + О2 → 2NO2
3) абсорбции оксидов азота водой
4NO2 + О2 + 2Н2О → 4HNO3
Суммарная реакция образования азотной кислоты выражается
NH3 + 2О2 → HNO3 + Н2О
