A further advantage derives from the fact that the integration between the ammonia and nitric acid production takes place through a by-product stream of the nitric acid process, i.e. Commercial grade nitric acid solutions are usually between 52% and 68% nitric acid. 2. The method as claimed in claim 1 wherein said contaminants are selected from the group consisting of nitrogen oxides. Process Emissions from Nitric Acid Manufacturing Process emissions from nitric acid plants consist primarily of nitric oxide ( NO), nitrogen dioxide (NO 2), and nitrogen oxide (NOx) from the tail gas of the acid absorptioin tower, nitrous oxide (N 2O), trace amounts of nitric acid (HNO 3) mist from the "Solid" nitric acid (up to 99 wt%) is needed for some natural and organic reactions of modern significance (Lefers, 1980). Abstract: Nitric acid is a highly corrosive mineral acid and is commonly used as a strong oxidizing agent. Some 60 million tons are produced annually, of which 80% goes into nitrate production for fertilizers and explosives, the latter principally for mining. Initially, large scale production of nitric acid began with sodium nitrate as a feed stock. An Fe/BEA powder catalyst prepared by Fe ion-exchange with steam-treated BEA zeolite was extruded in pellets and honeycombs. The article contains sections titled: 1.

Mainly there are three methods to prepare nitric acid but we choose Ostwald’s process or also known as ammonia oxidation process above all due to its advantages such as increased quality of nitric acid compared to other two process and a low operating cost. Initially, large scale production of nitric acid began with sodium nitrate as a feed stock. 1.2 Basics The azeotropic point for the nitric acid / water system is well known as a limitation for distillation. Nitric acid is a colorless liquid that is used in the manufacture of inorganic and organic nitrates and nitro compounds for fertilizers, dye intermediates, explosives, and many different organic chemicals. Most of the nitrogen oxides are found in the tail gases of the absorption tower. This complete five-casing nitric acid train was designed to sit on a steel base frame for an extra-short on-site assembly time. To investigate the feasibility of the simultaneous abatement of N 2 O and NO x in a single reactor, this field study was performed in a nitric acid production plant.
