In the event of an emergency power outage, are the electrolyzers in the chlorine production process sealed with brine or with fresh water?
I think whether it’s a chlorine plant or other electrolyzers, once they are shut down, the liquid should be drained as soon as possible; otherwise, it can cause serious damage to both the ion membrane and the coating.
When the electrolyte is drained, the membrane becomes exposed. Usually, such pauses in operation aren’t long; the vehicle will be driven again soon.
It’s best to use concentrated brine. It would be ideal if no fresh water were added to the brine in the tank before shutting down the system. However, in most cases, fresh water is added; in that case, there’s nothing that can be done. If there’s a sudden power outage and the backup power supply cannot be activated in time, or if there is no backup power supply at all, it becomes difficult to replace the brine mixed with fresh water with concentrated brine, which is quite problematic.
Operate in accordance with the operating manual of the chlorine engineering electrolyzer.
Specifically, it is still necessary to follow the chlorine engineering operating procedures. In Asahi Kasei, during normal emergency shutdowns, it is necessary to circulate the electrolytic cells; the residual electrolyte from electrolysis must not remain in the cells, as the gases and free chlorine present there can damage the ion exchange membrane. The resulting reverse current corrodes the coating. After parking, fresh brine is automatically supplied to the electrolyzer. If driving for 8 hours, the saline solution can be replaced. Otherwise, the brackish water circulates. When circulation on one or both sides stops, the electrolyte must be drained promptly. If it is not drained, bubbles are likely to form on the ion membrane at the bottom of the electrolytic cell.

Asahi Kasei. No information related to chlorine-free projects available. Haha
There’s no information related to chlorine engineering! But: The tanks used in chlorine processing must be operated in accordance with the chlorine processing operation manual – it’s essential! ! !

Could I take a look at the relevant materials? If it can be provided, there will be a substantial financial reward; thank you.

What I mentioned earlier refers to the procedures used in my own workplace. Later, I thought that the blistering of the membrane was my own opinion, not entirely based on the operating procedures.
