If nitrogen is mixed into liquid chlorine, nitric trichloride will not be formed
Nitrogen is an inert gas that reacts only under high temperature and pressure or other extreme conditions; for example, the synthesis of ammonia requires high pressure and catalytic agents to take place. In chlor-alkali production, nitrogen and liquid chlorine do not create the conditions for a reaction to occur. The original poster also understands that ammonia nitrogen is the cause of the formation of nitric trichloride, with this reaction occurring during the electrolysis process.
Ammonium mixed into liquid chlorine is dangerous.
It is ammonia produced by the electrolysis of impurities in the raw materials, as well as nitrogen trichloride generated during the production process
The quality of raw salt and water must be carefully controlled
If nitrogen is mixed into liquid chlorine, no nitric trichloride is formed; the formation of nitric trichloride occurs mainly when the total ammonia content exceeds the permissible level. Therefore, it is essential to maintain proper control over the quality of saltwater.
Ammonium ions combine with chloride ions under acidic conditions to form nitrogen trichloride.
Using nitrogen in liquid chlorine production does not cause any reactions. Nitrogen trichloride is formed when ammonium present in raw salts and water sources enters the system; as the brine enters the electrolyzer, ammonium reacts with chlorine to produce nitrogen trichloride, which then enters the chlorine system along with the chlorine gas, where it accumulates in the liquid chlorine production equipment.

The nitrogen-containing compounds in saltwater, such as inorganic ammonium salts or organic amines, react with hypochlorous acid under the conditions of electrolysis in an electrolyzer and a pH level of 2–4 in the anode solution, ultimately resulting in the formation of the explosive compound nitric trichloride.
Nitrogen-containing compounds such as inorganic ammonium salts or organic amines present in saline water will ultimately yield an explosive nitric trichloride compound under the conditions of electrolysis in an electrolyzer and an anode solution pH of 2 to 4. The reaction is as follows: NH3 + 3HClO → NCl3 + 3H2O. Nitrogen trichloride is generated during electrolysis due to the presence of ammonium (amines) in saline solutions, and it accumulates during the liquefaction and packaging of liquid chlorine; its concentration can reach the explosive limit.
