Actual output divided by theoretical output. Which method is the best, and why are there large differences in the calculation results? The fourth method involves using an alkali flow meter to get the theoretical yield, as well as calculating it by dividing the inventory on hand plus the sales volume by the theoretical yield. Which method do people use for calculations? hcbbs hcbbs

In production, the cathode efficiency is generally measured, and the fourth method is used. There is a significant difference between the results obtained using the two methods. I personally think the first method has a large error. This is because factors such as the analysis environment, personal errors, and instrument errors are all causes that affect the results.
Reply to 2# Wang Zhengxin: I also think that calculating the current efficiency based on the gas analysis data from test sheets results in significant errors. Additionally, the sulfate method is quite troublesome as well
The fourth method is generally used; the other methods are not used very often
The fourth method is the most intuitive and accurate, with fewer influencing factors and is easy to control
The fourth method is generally used, but due to concerns regarding the accuracy of the flow meter, significant errors can occur. However, the oxygen-containing method allows for the direct calculation of the anode efficiency, as well as determining whether enough acid has been added to the anode of the electrolyzer.
If the data are accurate, then the last option is the right one. Isn’t that what’s written in textbooks? It’s done to avoid inaccurate calculations of actual production volume
I feel that using actual output/theoretical output is what truly represents current efficiency, and it is the current efficiency that is beneficial for us
