Ammonia is a compound of nitrogen and hydrogen represented as NH3. It is a colourless gas with a characteristic pungent odour. It is produced by the process called Haber Process. Two molecules of hydrogen gas reacts with one molecule of nitrogen gas to produce two molecules of ammonia as given below:
3H2 + N2 ? 2NH3
The reaction is highly exothermic and lot of heat is generated during the process which is used for steam generation for captive use.
It is produced using Natural gas as the main feedstock. The other feeds required are Steam and Air. These feed materials undergo a series of reactions in the ammonia plant, before ammonia is produced in gaseous form. Ammonia is produced using steam reforming process. The technology is supplied by Kelloggs, USA. The installed capacity of ammonia plants is 10.02 Lakh MT per annum and expected to increase to 12.47 Lakh MT per annum post-revamp. Carbon Dioxide is the by- product of ammonia plant which is used for Urea production in Urea plant.
