Our company wants to recover ammonia from the shift stripping gas. We would like to ask if anyone here has any information on this topic. Request for assistance: QQ
This isn’t difficult; you can ask a design firm to prepare a plan for you
Add an ammonia stripping tower; that’s all. It’s essentially equivalent to an ammonia distillation tower. The value of recovery is limited (while there is a significant environmental benefit), and it’s mainly used for utilizing ammonia effectively. Further details would need to be discussed with a design firm.
Recycle or use for flue gas desulfurization and denitration
It is now in operation by the manufacturer. The process is as follows: The stripping vapor is first condensed to remove most of the non-condensable gases such as hydrogen sulfide, carbon monoxide, and carbon dioxide. The condensate is pumped to the ammonia stripping tower, where ammonia is vaporized to the top of the tower. The ammonia nitrogen concentration in the wastewater at the bottom of the tower is approximately 100PPM. Part of the ammonia nitrogen vapor at the top of the tower is condensed and used as reflux, while another part is absorbed in an absorption tower to produce ammonia water. The ammonia concentration can be controlled, generally ranging between 25–28%.
The petrochemical industry is quite mature; it depends on what you plan to do with the ammonia you recover
New Ao is already in use; you can ask
Ammonia is easy to recover. Are there any requirements for the recovered ammonia regarding hydrogen sulfide? If so, it becomes more complicated.
We just use it to heat the boiler right away – is it necessary to recycle it?
It mainly holds great environmental significance; Tianjin Chuangju, Zhongcheng Heyi, and Nanjing Dunxian all have operational achievements in this area
