Wet sulfuric acid process

The wet sulfuric acid process (WSA process) is a gas desulfurization process introduced by Danish company Haldor Topsoe in 1987. The WSA process can be applied in all industries where sulfur removal presents an issue, and produces commercial quality sulfuric acid (H2SO4) and high-pressure steam during desulfurization.
