Which electrolyzers have had a SIS system installed?
Thread Content
I would like to ask my colleagues: which chlor-alkali plant in China has implemented an SIS system for its chlor-alkali electrolyzer systems? According to Order No. 3116 issued by the General Administration of Work Safety, independent safety instrument systems (SIS) are required for two key types of facilities and one major project. Currently, such systems are being installed in liquid chlorine handling systems in China; the electrolysis process should also fall under this category. Manufacturers that have not yet implemented such systems are encouraged to share their experiences.
I’ve never heard of using a cell in an SIS system
If you know someone in charge of the relevant fields at Beihua Machinery, you can talk to them; they have worked on this for us, but so far they have not succeeded.
It’s necessary to install a SIS system for electrolysis systems, right? All the plants in our company that started operating in 2015 were required by safety regulations to have a SIS system. DCS is Zhejiang University Zhongkong’s SIS, and it was also developed by them

Our electrolysis system is equipped with an ESD emergency shutdown system.
Sodium hydroxide is produced by electrolysis. After electrolysis is complete, sodium chloride remains in the solution. How can sodium chloride be separated to produce pure sodium hydroxide? How is this process handled in industry?

First of all, there are no absolutely pure substances in the world at present; therefore, I’m not sure what purity level you’re referring to for pure sodium hydroxide What is referred to as electrolysis these days is usually ion-exchange membrane electrolysis; the amount of sodium chloride contained in the alkaline solution is very low, at the ppm level, which is sufficient to meet the production needs of the vast majority of downstream enterprises
