The WSA process is a wet gas catalytic process. The concentrated sulfuric acid is produced by condensation from a wet process gas. Drying of the process gas prior to treatment in a WSA plant, therefore, becomes superfluous, hence generation of wastewater and loss of sulfur are avoided.

SO3 then is dissolved in concentrated sulfuric acid forming fuming sulfuric acid (oleum). This can then be reacted safely with water to produce concentrated sulfuric acid. Major changes have been made in process and plant design to maximize energy recovery and then use this heat to generate high-pressure steam and/or electricity.

In chlorine manufacturing plants, the produced chlorine gas is dried by the means of sulfuric acid, which is consequently diluted. Typically, such diluted sulfuric acid is leaving this drying step at 75–78 wt% and needs to be re-concentrated to 96 wt% — or even 98 wt% — in order to be able to be reused.
