Produce directly from spent acid, elemental sulfur or sulfur compound containing gases  Whether you produce sulfuric acid from elemental sulfur or from SO2 regenerate spent sulfuric acid or clean sulfurous gases, we have the optimal solution.

Our high activity catalysts provide high conversion, high energy efficiency, low-pressure drop, production stability, as well as an exceptionally long life in any sulfuric acid plant. They ensure that our customers achieve higher production rates, improved heat recovery, fast start-up, optimal energy efficiency and the lowest possible SO2 emissions. Our Wet gas Sulfuric Acid (WSA) technology converts sulfurous gases to commercial-grade sulfuric acid without drying the gas, with a high energy efficiency and very low emissions.
