Ammonium Hydroxide Proposal Nov 2014

2020-5-8  Ammonium hydroxide is a powerful alkali petitioned for use as a boiler additive because it neutralizes carbonic acid in condensate to prevent corrosion, reducing pH to 8.5 or 9.0. The level of ammonium hydroxide required in steam would depend on the level of carbon dioxide in the steam. Ammonium hydroxide is produced by the addition of water to Ammonia. Ammonia is produced on a large scale worldwide. One of its largest uses
