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.
Based on experience over more than half a century, Topsoe has established an extensive technical service programme available to our VK catalyst users. In addition to frequent contact, the service programme includes activity testing of catalyst samples, evaluations of catalyst performance, plant optimization, troubleshooting and management of catalyst replacement.
Activity testing of catalyst samples represents a valuable source of information, which combined with data evaluations of the plant performance enables Topsoe to optimize future catalyst management.
