Reasons for the excess level of free chlorine in high-purity hydrochloric acid

There’s a problem with the chlorine to hydrogen ratio; too much chlorine is present
1. Excess chlorine gas or low hydrogen flow rate. 2. Frequent fluctuations in chlorine and hydrogen pressures. 3. Damaged quartz lamp head, resulting in incomplete chlorine-hydrogen reaction
Agreeing with the above analysis, it should be added that whether the free chlorine level in the desalinated water used for water or high-purity acids is excessive also directly affects the free chlorine level in the acids. In fact, this issue touches on a very important point: the overall level of chlor-alkali production technology in our country for hydrogen chloride synthesis has not yet reached a stage where complete automatic control is available, thereby ensuring full control over the hydrogen chloride ratio in the synthesis process.
