How is the current efficiency of an electrolyzer determined

Some people say that current equivalents should be used for calculations; for example, if there are a number of electrolyzers, each with b cells, with a current equivalent of c, and the total current from all the electrolyzers being d, then the theoretical chlorine production amount would be: a*b*c*d*10^-3. The current efficiency would then be: actual mass of chlorine / theoretical mass of chlorine. Is this calculation method correct? If possible, I would like to ask whether the current equivalent varies depending on the electrolyzer? Thank you! # hcbbs
The current efficiency of the ion-exchange membrane cathode is the ratio of the actual amount of alkali produced to the theoretical amount. The efficiency CE = Actual alkali production / Theoretical alkali production × 100% = (Theoretical alkali production – Alkali loss due to OH’ migration) / Theoretical alkali production × 100%. The current equivalent is related to the type of ion-exchange membrane slot selected
2# It’s beneficial to learn more. I’d like to ask further: is it more accurate to use caustic soda instead of chlorine, since chlorine leads to losses due to dissolution and emission, while caustic soda has little or no such losses?
Current efficiency is divided into cathode current efficiency and anode current efficiency. The calculation for cathode current efficiency is relatively simple: actual alkali output/theoretical alkali output * 100%； The calculation of anode current efficiency is complex, and it is related to factors such as the operating current of the cell, the number of cell frames, the flow rate of brine entering the cell, as well as the acidity of the brine at the inlet and outlet

The last edit to this post was made by Yinozhang on 2009-11-21 at 20:55; controlling power consumption is the right approach
Current efficiency is composed of cathode efficiency and anode efficiency, both of which are the ratio of actual output to theoretical output
