How is ammonia nitrogen generated in the sodium-alkali desulfurization slurry?
Thread Content
Our sulfur recovery unit employs the conventional three-stage Claus process combined with the sodium-alkali method for desulfurization. Upon analyzing the desulfurization slurry using this method, ammonia nitrogen was found to be present in it; however, the source of this ammonia nitrogen has not yet been identified. Are there any effective measures for dealing with it? I would like to ask the experts here: if any of you are aware of this matter, please share your insights.
If the temperature in the sulfur production furnace is not high, nitrogen oxides are generated; moreover, excessive air supply or an inadequate ammonia combustion effect generally lead to the formation of nitrogen oxides. It is recommended to adjust the temperature to 1250 degrees Celsius
