Procedure

The formic acid is also neutralized by ammonia, to make ammonium formate as another wastewater constituent. The acidic gases carbon dioxide and hydrogen sulfide are also components of the syngas, but are not very water soluble. Most of the remaining ammonia in the gasification wastewater which is not neutralized by chloride or formate reacts as the ammonium ion with the anionic forms of the acid gases carbon dioxide and hydrogen sulfide to form bicarbonate or carbonate depending on the pH, and bisulfide.
