Excessive free chlorine and salts in the pipeline due to resistance to fluorine corrosion
Thread Content
We have a two-in-one furnace, a planetary film absorber, a pure water tank for supplying the flow injector, and an absorber for acid production. During recent acid production, the free chlorine level in the brine exceeded 20–40 ppm, and the cause has not yet been identified. A few days ago, there was a corroded hole in a short section of the water absorption pipe; after it was replaced, the salt and acid levels were normal.

Could chlorine have gotten in? Obviously, that’s quite unlikely. I think we should start by checking the chlorine-to-hydrogen ratio in the synthesis furnace, as well as the color of the flames produced by it. These two reasons account for an extremely large proportion.
