How to separate sodium carbonate solution from sodium formate solution
Thread Content
The concentration of sodium carbonate solution in sodium formate solution is too high. What method can be used to separate the sodium carbonate solution.
The sodium carbonate solution is more alkaline. Can this be used for separation? Is it just to simply reduce the concentration of sodium carbonate in the solution or does it need to be recycled?
Probably not, my idea is to use solubility for separation
This is a problem. At present, many manufacturers don't seem to think too much about it.
For two different salts, try crystallization separation.
Formic acid is stronger than carbonic acid. CO2 can be released by adding formic acid and heating.
Adding formic acid should be feasible, but the economy is too poor
I think the best way is to consider gas purification, remove CO2 in advance, and both water washing and alkali washing can meet the requirements.
