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.
