The Ammonia Process
Ammonia is the building block for all nitrogen fertilizer
One Nitrogen atom is bonded to three Hydrogen atomsatoms
The feedstocks necessary to make ammonia are very simple – natural gas and air

The Ammonia Process
The ammonia process is not so simple – it involves high pressure, high temperature, seven different g p , g p ,catalytic reactions ….. (Control Room)
And a great deal of complicated equipment and instrumentation

The Ammonium Nitrate Process
Then you react nitric acid with ammonia in a neutralizer

The UAN Manufacturing Process
Both urea and ammonium nitrate are first manufactured as solutions (78% - 87% strength) ( g )
Mixed to make UAN
28% - 32% N(UAN Plant)

The Solid Fertilizer Manufacturing Process
Both urea and ammonium nitrate can also be concentrated and dried under controlled conditions to make granular urea or prilled ammonium nitrate
