Reaction Steps
For the ammonia process, the solvent solution consists of ammonium, bicarbonate ions and to a lesser extent, carbonate, in equilibrium with dissolved ammonia (aqueous), and dissolved CO2 (aqueous). In the absorber, water and ammonia react with CO2 (aqueous) to form bicarbonate ions or ammonium carbamate ions, with the reaction reversed in the stripper by the application of energy. The relevant aqueous phase reactions can be summarized by the following overall equations: CO2+H2O+NH3HCO3−+NH4+ (eqn. 1) CO2+2NH3NH2COO−+NH4+ (eqn. 2) HCO3−+NH3CO32−+NH4+ (eqn. 3) CO32−+H2O+CO22HCO3− (eqn. 4)
