The problem of excessive foam formation due to sodium carbonate alkaline ash neutralization
Thread Content
A new salt-containing wastewater incineration unit has been installed, which generates large amounts of sodium carbonate salts. A dissolution and neutralization system was designed and experiments were conducted; during the neutralization process, a large amount of CO2 gas is produced along with plenty of foam. There is concern that this excessive foam could lead to flooding, similar to beer foam, and prevent the unit from functioning properly. I would appreciate any suggestions or methods that might help address this issue. Thank you
This is an acid-base neutralization reaction taking place; the bubbles are carbon dioxide, and they are difficult to deal with. You can try adding defoaming equipment
Physical spraying, or using an antifoaming agent to eliminate foam
