Acid concentration in the drying tower

This post was last edited by Oath-taking on 2011-10-23 09:38. What is the acid concentration in everyone’s air drying towers? Is there a difference between 94% and 98%?
We keep the acidity level of our dry air at 94%. A level of 98% provides a slightly better drying effect than 93%, but the gas tends to contain acid mist
The drying effect should be maintained at around 93.5%.
The acid concentration in the drying tower depends on the configuration of the tank system; if a separate circulation tank is provided for the drying tower, a concentration of 93% is preferable； If the circulation tank is shared with a absorption tower, it can only be 98% acid. (For units that produce 98% acid)
