What to do if severe foaming occurs during decarburization with an amine solution?

Decarburization using amine solution, carbon dioxide in gas
Generally, an antifoaming agent is added, but its dosage must be controlled. If desulfurization is carried out first, special attention should be paid to preventing liquid from being carried over during the desulfurization process.

Is the amine solution concentration too high? Try reducing the concentration of the amine solution
What amine is used? Try MDEA. Was an antifoaming agent added?
I think we need to check the solution to find the cause; we can’t just add an antifoaming agent
It is said that simply adding an antifoaming agent does not yield good results

1. Check the gas at the inlet of the MDEA solution absorption tower to see if it contains impurities. 2. Check whether impurities from the tower have mixed into the MDEA solution. 3. MDEA has filters in both the regeneration and absorption lines; try cleaning them several more times to see how it works 4. The source of the bubbles cannot be identified; instead, only defoamers are added, so the results in the long term will likely be mediocre.
