What is the approximate temperature of the electrolytic catholyte after passing through the catholyte heat exchanger and entering the electrolytic cell? Why is it necessary to keep it within this temperature range?
It depends on the temperature requirements of the electrolyzer.
Each current density corresponds to an optimal temperature, with current efficiency being the main consideration.
The temperature of the alkali coming out of the heat exchanger is controlled based on the requirements for the tank temperature.
Asahi Kasei generally requires that the temperature of the electrolyzer cell not exceed 90°C; therefore, it depends on how you manage this situation. If the system is operating at full capacity, the 273 heat exchanger needs to be cooled down. If it’s not operating at full capacity, it depends on the specific procedures to be followed. In any case, the goal is to improve current efficiency or at least not affect it.
