Does an oxygen content of 1.1% in chlorine affect the purity of chlorine gas?

Recently, in one of our company’s 6 Taipei Chemical Machinery natural circulation membrane electrode distance electrolyzers, the oxygen content in the chlorine was 1.1%, the purity of the chlorine gas was 98.6%, and the hydrogen content in the chlorine was 0.07%. I would like to ask experts: does a high oxygen content in the chlorine affect the purity of the chlorine gas?
Based on your data, the oxygen content is already affecting the purity of chlorine, with levels exceeding 1%.
The coating used in the electrolyzers produced by Beihua Machinery is a low-oxygen coating, with an oxygen content generally below 0.5; this is the same as that used by Asahi Kasei. How many years has your company been in operation?
It will be a year next month since our company’s electrolyzers were put into operation. During operation, various problems have arisen due to factors such as raw salt, resulting in excessive levels of impurities like Fe, I, and Si in the electrolyzers
Yes! An ion membrane analysis was conducted, but the ICP test on our company’s secondary brine showed that only silicon levels were above the standard
The oxygen purity is low while the hydrogen content is high; increase the amount of acid added. If the membrane is in its later stages of use, consider replacing it
Also note that both the pH of the saline solution and sulfate ions have an impact on the oxygen content
According to Asahi Kasei experts, there is a high possibility that the water permeability of the ion membrane will increase
