The improved ADA desulfurization process uses sodium carbonate as the absorbent. Can sodium hydroxide be used as an absorbent? Why?

Could you explain why sodium hydroxide is not used as an absorbent?

In the improved ADA desulfurization process, sodium carbonate participates in the reaction and can be reused after regeneration. Sodium hydroxide seems not to work, right?

Alkali is not used in wet flue gas desulfurization for two reasons: 1. It is difficult to create a stable buffer solution system, which prevents the JPH value from remaining stable； 2. High corrosivity.

I really didn’t expect the issue with the buffer solution; thanks for sharing.
