The amount of ammonia and nitrogen in the water used for purifying acidic gas streams is unstable
Thread Content
We have an acidic water gas treatment system, and at present the system is operating smoothly. The temperature at the top of the tower is 100–102°C, while the temperature at the bottom of the tower is 122–124°C. The pressure at the top of the tower is 0.1 MPa. However, the ammonia nitrogen content in the purified water coming out of the bottom of the tower varies greatly – sometimes it’s 50 ppm, and other times it’s 4000–5000 ppm; this level is very unstable. The requirement is that the ammonia nitrogen content in the wastewater should not exceed 150 ppm. Right now, the purified water produced cannot be discharged into the sewage treatment system; could everyone please help me come up with a solution?
Does the stripping tower have automatic ammonia removal equipment?
