Issues with the effluent from the ammonia purification tower
Thread Content
The ammonia purification tower contains liquid ammonia, and it is necessary to drain the liquid from the bottom of the tower after a while, as liquid ammonia is used to absorb hydrogen sulfide from the ammonia gas. However, when the drainage line is opened, the liquid level at the bottom of the tower drops very slowly. I’m not sure what the reason is; how should this be dealt with? Please share your thoughts, thank you
Ensure proper three-stage separation; minimize hydrogen sulfide levels here to prevent salt formation.
