An ammonia smell is coming from the hydrogen system
Thread Content
After emerging from the cathode of the electrolyzer, hydrogen passes through a positive-pressure water seal before entering the hydrogen scrubber and then the hydrogen tank. Recently, there has been drainage from the hydrogen tanks and the inlet pipes of the hydrogen compressors, and the water discharged from the hydrogen buffer tanks at stages 1–4 of the hydrogen compressor has a strong ammonia smell. Could the seniors help analyze what’s going on?
Have you purged the pipelines attached to this gas holder with nitrogen?
It has been replaced; the ammonia smell appears during normal operation
Under normal circumstances, hydrogen needs to be in certain conditions to react with nitrogen to form ammonia; it is recommended to check the process
Hello, in our hydrogen press, the highest pressure is achieved in the fourth cylinder, at 1.0 MPa, with an exhaust temperature of 120°C. Under such conditions, it is basically impossible for hydrogen to react with nitrogen; moreover, under normal operation, there is no nitrogen in the hydrogen system.
It’s very likely that the water seal contains NH3~~~
Is there a cooler for hydrogen? If it is available, find out what type of chiller supplies the chilled water being used
