How to control the free acid in saturated crystalline sulfuric acid from ammonia-based desulfurization
The simplest way is to add ammonia: lol. Let’s see if anyone else has any good ideas?
Shouldn’t the circulating liquid be weakly acidic?
Regarding the free acid content, there are no effective measures in the saturated process within the tower; however, by using external evaporation crystallization and adding a conditioning tank before the material enters the evaporation crystallizer, the free acid content can be significantly reduced.
