Some issues in the caustic soda electrolysis cycle
Thread Content
In the ion-exchange membrane caustic soda electrolysis process, what is the ratio of concentrated brine to dilute brine fed into the anode cell? Also, what is the volume of alkali solution that circulates at the cathode? Thank you; I’m new to this and need some help
Brine solution: fresh water to brine = 1:6.5. Increasing the circulation volume is beneficial for the membrane, as it prevents erosion; a lower amount of brine will result in a lower voltage
Hello, may I ask if the concept of specific gravity is used in chlor-alkali accounting?
The catholyte circulation rate is 300 L per unit, with a ratio of brine to fresh water of 1:7
Hello, may I ask how the size of equipment such as the brine sump used in the electrolysis process is determined? The teacher said (taking the brine sump as an example) that it should be sized to cover the volume on the anode side, plus an additional volume to account for potential issues with pumps and other equipment, as well as to allow time for proper processing. . But I’m dealing with 100,000 tons of ion-exchange membrane caustic soda; official data indicates a volume of 28 cubic meters, while my calculations show a volume of over 50 cubic meters, which is twice as much. How should I choose the appropriate model in this case? Thank you
