Treatment of liquid ammonia entering circulating water
Thread Content
Every time the plant **units are started up, liquid ammonia always ends up in the circulating water of the urea production workshop, which affects the quality of the cooling water. What are some effective methods for preventing this problem? A situation such as a leak in the ammonia cooler can also lead to this outcome.
1\ The multiple circulating water fans serve a stripping function. 2\ The quality of the circulating water itself has a nitrification effect, converting ammonia nitrogen into other forms of nitrogen.
