The wet sulfuric acid process (WSA process) is a gas desulfurization process. After Danish company Haldor Topsoe introduced this technology in 1987, it has been recognized as a process for recovering sulfur from various process gases in the form of commercial quality sulfuric acid (H2SO4) with the simultaneous production of high-pressure steam. The WSA process can be applied in all industries where sulfur removal presents an issue.
The wet catalysis process is used for processing sulfur-containing streams, such as:[1]
H2S gas from e.g. amine gas treating unit
Off-gas from sour water stripper (SWS) gas
Off-gas from Rectisol
Spent acid from an alkylation unit
Claus process tail gas
Heavy residue or petcoke-fired utility boiler off-gas
Boiler flue gases from various processes SNOX flue gas desulfurization
Metallurgical process gas
Production of sulfuric acid
