Reasons for excessive free chlorine in high-purity hydrochloric acid

Hydrogen chloride is over-chlorinated, either due to contamination during transportation; the poster claims that there are no issues with the production process – are they really that sure?
Many companies use tap water to produce hydrochloric acid in order to improve economic efficiency; our company used to do the same, but later switched to pure water. I wonder what kind of water you guys use
During the operation of the hydrochloric acid synthesis furnace, an improper chlorine to hydrogen ratio is the most likely cause; pure water must be used for absorbing water in high-purity hydrochloric acid
We also use pure water, and we have replaced whatever needed to be replaced in terms of mixing ratios and pipelines. . . .
Check whether the flow ratio of chlorine to hydrogen is appropriate; in many cases, flow meters are not very accurate, so it is necessary to judge based on the color of the flame. If everything is confirmed to be fine, it is recommended that you reinstall the lamp holder.
