What determines the purity of electrolytic chlorine?

As the original poster said, the purity of chlorine in the individual channels is high, while the purity of chlorine in the main pipeline is not high. It is necessary to check whether the chlorine flowing into the main pipeline all has high purity, as well as whether there are any leaks due to negative pressure. It should also be determined whether the chlorine recovered from some saltwater tanks is being fed into the main chlorine pipeline. This post was last edited by limingshuguang on 2009-4-11 11:18.]
Check whether excessive negative pressure is causing air to be drawn in, and inspect the main pipe for any leaks.
If it is operating under negative pressure, there may be a leak in the main pipe, allowing air to enter.
The purity of the chlorine gas in the main pipeline is not high; it is necessary to check the negative pressure water seal for chlorine gas, especially during the process of increasing current in the electrolyzer. If the negative pressure control fails, it can damage the water seal. The personnel responsible for checking the water seal do not carry out their tasks carefully, which can easily affect the purity of the chlorine gas and thus impact the liquefaction process!
Please start your analysis with the methods for measuring chlorine purity! Chlorine reacts with water, thereby affecting its purity! There is relevant information online!
If the purity of the chlorine in the main pipeline is not high, check along the pipeline to see where there is a sudden change.
The seals of some devices can leak; in our compressors, a small amount of nitrogen gets in through the seals
Reduce the leakage of chlorine from the cathode chamber to the anode chamber, and prevent the generation of hydrogen when there are iron impurities in the anode solution or on the diaphragm. The chlorine content can be increased
What is the purity of your chlorine? Where are the specific testing points located?
It’s possible that air has entered the chlorine main pipe, or the make-up valve isn’t closed properly.
