Corrosion of pipes and equipment; substandard liquid chlorine products
If the moisture level in the drying system remains too high and cannot be reduced, it not only leads to increased acid consumption in this processing step but also causes severe corrosion of the pipes and equipment in the subsequent freezing stage, thereby reducing their service life; over time, leakage accidents may even occur.
Thank you all for your guidance. It is said that the equipment with the greatest impact is likely the chlorine compressor (turbine); it is said that the high-speed rotating impeller can cause explosions when in contact with rust particles that have corroded and fallen off within the system. Has anyone seen any such incidents?
Consume more sulfuric acid； Corrode pipes, corrode compressors

It’s true – excessive moisture content has a severe impact on chlorine gas turbines; generally, the moisture level should be kept below 100PPM, with lower levels being preferable. This places higher demands on the drying system. If an excess of moisture is detected, it definitely indicates a problem with the drying system (such as a punctured refrigeration pipe, etc.). When the value exceeds the alarm limit, the only option is to shut down the system urgently to protect the turbine, as these are valuable equipment that cost a lot of money, and care must be taken

It reduces the lifespan of the turbine, affects the service life of subsequent pipeline equipment, and also has an impact on liquefaction processes. Using sulfuric acid or similar substances for drying also results in losses, as poor drying efficiency leads to unnecessary leakage due to the automatic overflow of sulfuric acid. In my personal opinion, not to mention me!
High water content certainly causes corrosion in pipelines; most importantly, it leads to corrosion of the impellers in compressors (turbines), resulting in a decrease in the suction capacity of those turbines. At the same time, attention must also be paid to internal leaks in the turbine heat exchangers; explosions can occur as a result of friction caused by corroded and detached rust particles. I’ve never heard of such incidents, and I think it’s unlikely to happen. If there were rust particles, the rotating impeller would have been damaged long ago. High temperatures can indeed cause \"chlorine fires\"·
We’ve already talked about the factors that have an impact. Could you explain the reasons for the increase? We conducted sampling and analysis to determine the cause; with the same operational controls, changing the sampling method reduced the level from 180PPm to 87PPm. No signs of corrosion were found during the inspection of the turbine. From a production control perspective, what factors can have an impact?
