Wet chlorine compressor

Haha, I’m in charge of the chlorine compressor just now. Chlorine reacts with water to produce HCl and HClO; no metal that can resist corrosion by these two substances has yet been developed. If someone insists on mentioning Hastelloy and titanium materials, keep in mind that chlorine compressors are rotating equipment, with ordinary models reaching speeds of up to 10,000 rpm. Metal corrosion prevention is achieved by forming a dense oxide film on the metal surface; however, at speeds of tens of thousands of revolutions per minute, this oxide film is continuously worn away by wet chlorine gas! Note that abrasion is the main cause of continuous corrosion of metals, which is why no metal type is suitable for manufacturing compressor rotors. Also, please note that the shaft must be able to withstand the large torque it has to carry. The shaft of a compressor is generally best made of carbon steel. Seals and materials for the shaft are also basically unavailable. The core equipment in the chlor-alkali sector is the compressor, and the air volume delivered by the compressor also affects the system’s production capacity; compressors that are non-metallic and produce a low air volume at low speeds are not considered. It would be better to dry the chlorine first; dried chlorine does not react with iron. Creating a system that uses concentrated sulfuric acid to dry the chlorine is much less troublesome than dealing with compressors that are prone to corrosion
