How should the sulfuric acid coming out of the drying tower be handled?

I would like to ask the experts: when using 98% concentrated sulfuric acid to dry SO2 gas, to what concentration can the sulfuric acid be diluted after drying? What is done with this sulfuric acid afterward? What is the difference between 98% sulfuric acid drying towers and 93% sulfuric acid drying towers?
Sulfur is used to produce acid; the dried dust is returned to the acid tank directly for reuse in the circulation process
It is generally reduced by 0.3 points, with the concentrations of various systems maintained through mutual acid exchange.
85% can be achieved; of course, sulfuric acid can also be supplied additionally
Thank you for the reply. The moisture it absorbs when dried actually has little impact on sulfuric acid products, right?
What process is usually used to obtain 93 acid? Why is it set to 93?
Mutual acid stringing refers to using fuming sulfuric acid or acids of higher concentration to maintain the acid concentration?
Neither, I just want to learn* understand this industrial process
