Green AAG
The vehicle for hydrogen economy
Technology
A. The Production Process
The production process of the green fertilizer consists of the following steps
- Green Hydrogen (GH2) is Produced by Electrolysis of Water using the Renewable Energy from the CSTP Project; 2H2O → 2H2 + O2
- Nitrogen is produced by conventional air Separation Technology (PSA) from Air.
- Then Ammonia is Synthesized in a conventional Haber Bosch Process Unit that utilizes only Renewable Energy; thus the product is called ‘Green Ammonia’ N2 + 3H2 → 2NH3 [Green Ammonia]
- Green Ammonia(gas) so produced is then converted to Di-Ammonium Phosphate (DAP) in the Fertilizer Production Unit by reaction of Phosphoric Acid thus the ‘Green DAP’ is produced; NH3 + H3PO4 → (NH4)2HPO4 [Di-Ammonium Phosphate]
- Ammonia(gas) may directly be injected to soil as source of Nitrogen or the same may be converted to ammoniacl liquid fertilizer as liquer ammonia NH3 + H2O → (NH4)OH [Ammonia Liquer]
