How to choose a compressor for wet chlorine?
Thread Content
As the title suggests, the chlorine gas produced by electrolysis currently has a high moisture content. It needs to be sent to the next processing stage for further reaction, but this reaction requires a certain pressure. Using drying equipment not only increases costs but also generates more waste. Therefore, I was wondering if there are any compressors that can handle moist chlorine gas
There is none at the moment, for the following reasons: 1. The chlorine gas at the outlet of the electrolyzer is not washed with water, resulting in a relatively high water content in the titanium coolant. 2. A larger water volume increases the compressor’s corrosion resistance, which in turn raises the cost. 3. During the gas compression process, condensate may form, which can cause liquid slugging in the compressor. Destroy equipment. Furthermore, with a large volume of water, the material requirements for the downstream treatment units also increase significantly; therefore, your idea is not cost-effective. Feel free to communicate.
Thank you so much!~ I would like to ask again: if we consider economically viable options, how should this process be designed?
What does that mean? The chlor-alkali process is highly mature. It’s likely very difficult to design something for compressing water removal.

Yes, this is also why the chlor-alkali industry has, over the years, continued to use the process of drying with sulfuric acid first and then compression.
Add a drying tower and a washing tower to reduce moisture in the chlorine gas temperature gauge
If the downstream process has no requirements regarding water content in chlorine, it is theoretically possible to use a water-ring pump made of titanium for pressurization, though no practical applications of this have been reported.
