Regarding wood electrolyzers, the issue of nitrogen filling on the anode side during single-cell anode shutdown
Thread Content
Regarding the Wood electrolyzer, the issue of nitrogen filling on the anode side when stopping a single cell: To protect the electrolyzer, our plant previously followed strict procedures of filling both the anode and cathode sides with nitrogen； Due to subsequent abnormalities, we are considering stopping nitrogen injection on the anode side of the single-tank shutdown process; please discuss whether this is feasible ；
Nippon Asahi Kasei has designed it in such a way that the parking anode is not filled with nitrogen; by opening the valve at the back of the tank, air can enter directly, and it will then be able to enter the chlorine negative pressure system.
Nitrogen is introduced into the anode to prevent harmful gases such as chlorine from entering the anode system and damaging the ion membrane. As long as the anode gas phase is free of harmful gases at the site, the nitrogen supply can likely be stopped.
The purpose is to maintain a positive voltage on the anode to prevent chlorine from entering.
If I were to write it as a thesis, what types of books should I refer to?
