Does amine solution absorb SO2?
Thread Content
Could experts please tell me whether amine solutions, especially lean solutions, can absorb sulfur dioxide? Is their absorption capacity strong or weak? Please discuss this; many thanks

Substances with greater acidity can certainly also be absorbed, and not only that – it’s difficult to desorb them as well.
Sulfur dioxide is acidic; upon absorption it forms salts, which are difficult to regenerate.
