Why is the ammonia nitrogen level always high in compressed positions?
Thread Content
We are a small nitrogen fertilizer factory that uses reciprocating compressors. Lately, the ammonia nitrogen level in the wastewater discharged by these compressors has been very high, exceeding 1,000, which causes the water entering the wastewater treatment system to always exceed the allowed limits. Does anyone know how to reduce this ammonia nitrogen level? After some analysis, it seems that the high level of discharge from one of the separators is likely due to substances brought in from the desulfurization unit; however, it’s not clear what to do about it
Too fast gas flow carries liquid, lowering the temperature of the gas upon entry and reducing the amount of water carried in during compression. The poster should use ammonia to remove sulfur; it’s possible to control the concentration of ammonia used for this purpose.
