How to determine trace chlorine after dechlorination
Thread Content
Everyone, we currently use equipment from Huaxi for hydrogen production, with the raw material hydrogen coming from chlor-alkali process emissions. There is a dechlorination adsorption tower in the production process. Previously, we installed an online analyzer for detecting trace amounts of chlorine during the R&D phase, but it has not been able to function properly. I would like to ask if anyone knows of any reliable analyzers (either online or offline) or other easy-to-use methods that can accurately measure the trace amounts of chlorine in hydrogen. I appreciate any advice you can provide. Thank you!
It is usually chemical titration, or ICP analysis. If analyzed online, is this chlorinated substance constant?
A microcoulometer can detect 0.1 ppm of chlorine, offline
The most advanced models available can only detect 1, which is not very accurate; it is recommended to add another set for washing
