FCCU adopts SCR denitrification process + EDV (or WGS) desulfurization process. Is there any excessive discharge of high-concentration salty sewage NH3-N? What range does it need to control the escape of NH3 at the SCR outlet?

Theoretically, it will not exceed the standard, and the designed ammonia escape amount is controlled below about 3ppm.

It will definitely exceed because there is a large amount of ammonia, and the ammonia nitrogen in the water will be around 10,000. It is best to use a gas device for post-processing of the tower! Analyze ammonia nitrogen content!
