What are the process differences between various ion membrane electrolyzers?
Thread Content
Dear sea friends, during the early days when ion membrane electrolyzers were introduced in our country, our impression was that the electrolysis process relied on forced circulation; there were no saltwater or alkali sumps, only natural circulation tanks； Later, the natural circulation electrolyzer for chlorine production overturned the conventional notions we had. So, for the electrolyzers that everyone has come across, what is the design like for the associated high-level tanks – are they present or not? We welcome everyone to actively participate in discussions to boost the forum’s activity, with rewards available.
Beihua Machinery, membrane pole distance, there is a high-level tank
Both the natural circulation electrolyzers of Beihua Machinery and Asahi Kasei are equipped with high-level tanks. The electrolyzers in chlorine production plants do not have head tanks.
In the acid addition process for electrolyzers, some manufacturers add acid before the brine sump, utilizing the gas pipe in the sump to release gases such as CO2, with a small amount being added at the inlet of each cell.
The acid addition process in Asahi Kasei’s electrolyzers can be carried out before the brine feed tank or at the inlet of each individual cell.
Add acid in front of the saline sump? ? Can the pipes and tanks withstand this acidity?
