Nitric Acid: Ammonia
built 657 days ago
Nitric acid is produced by the catalytic oxidation of ammonia. It is manufactured in quantity mainly for use in the production of nitrogenous plant nutrients. Some of the nitric acid produced is held in storage for onward sale to customers.

An environmental impact assessment was carried out in relation to the construction of the nitric acid plant KD 6. After a public discussion, the Ministry of Environment declared that it was in favour of the construction of the production plant. The plant ... delivers steam which Lovochemie says provides significant savings in terms of fuel. At the same time the consumption of ammonia per unit of produced nitric acid as well as emissions of nitrogen oxide is reduced. The facility complies with tough EC emission limits.

Humans generate nitric acid wherever very high temperature combustion takes place in the atmosphere in the presence of nitrogen, oxygen and water. The exhausts of incinerators or other chemical plants and the tailpipes of cars and trucks are common sources. Because it is so reactive with other compounds, nitric acid does not remain in Earth's atmosphere for long. Nitric acid reacts with gaseous ammonia to form particulate or aerosol nitrate, removing the nitric acid from the atmosphere within a few days of its creation.

Ammonia and nitric acid are ... heavy chemicals. They are made from nitrogen gas, which can be obtained by separating it from oxygen and the other gases that are present along with nitrogen in the atmosphere.

Faraday's fourth lecture includes demonstrations of the preparation and properties of two different acids (nitric and hydrochloric) and gases such as ammonia, hydrogen chloride and chlorine. He demonstrates the properties of these substances, through the use of indicators, illustrates the acid/base character of these substances and shows some of their useful properties.
