Concentration control of sodium hydroxide in chlor-alkali process
Thread Content
Experts, I have a question: in the chlor-alkali process, the concentration of sodium hydroxide should increase over time. How can we maintain a stable concentration of sodium hydroxide? Are there any pipeline instruments that can detect the concentration of strong sodium oxide? I intend to use chlor-alkali technology, in which chlorine gas reacts with sodium hydroxide to produce sodium hypochlorite. Additionally, sodium hydroxide reacts with carbon dioxide in the air. In the chlor-alkali process, how is sodium hydroxide processed to obtain a higher-purity product? I would appreciate it if all the experts could help me with this. Thank you
Are there any pipeline instruments that can detect the concentration of strong sodium oxide? ---There are concentration monitors. In the alkaline process, how is sodium hydroxide processed to obtain sodium hydroxide of high purity? ----Electrolysis of brine (ion-exchange membrane electrolysis process); the production process determines the mass concentration
Thank you. One more question: how can the concentration of sodium hydroxide be kept stable? ? Add water?
Equipment selection, process parameters, etc., determine the concentration of caustic soda in the electrolytic cell; this concentration range is rather narrow. If a higher concentration is desired, evaporation and concentration are required. If a lower-concentration caustic soda solution is needed, simply dilute it with water
Okay, thank you,:handshake
