Our facility discharges directly, but the ammonia nitrogen level in it is high, polluting other water sources! Does anyone know what impurities are contained in them? How should these waters be handled properly?
After stripping, it is sent to the desalinated water station for treatment.
Sent to the circulating water system, where chemical treatment is carried out in a cyclic manner.
Ammonia nitrogen is produced through the pure oxygen steam conversion reaction.
The design calls for biochemical treatment; currently, it is either discharged on-site or through coking quenching.
We send it to synthesis and distillation after gas lift and condensation!
Currently, gas lift towers are generally installed in the conversion section; after gas lifting, the liquid is sent to the desalinated water station or for circulating water treatment, and this varies from plant to plant
After passing through the stripping tower, it is sent to the desalinated water cooler; after cooling, it is sent to the desalinated water station
