Topsoe's sulphuric acid catalysts

Topsoe's catalyst portfolio for sulphuric acid production is uniquely balanced to combine high and stable activity, robustness, low pressure drop and a long service life.

By combining outstanding activity with low pressure drop and exceptionally high mechanical strength, the VK catalysts ensure cost-effective plant operation by providing

• high SO2 conversion efficiency   
• improved energy efficiency 
• enhanced operating flexibility 
• low screening losses 
• long service life

Topsoe’s VK series of catalysts are comprised of five different formulations in a variety of sizes and shapes, effectively covering all operating conditions in any sulphuric acid plant.

Topsoe's wet gas sulphuric acid process

On the technology side, Topsoe offers its WSA process (Wet gas Sulphuric Acid), which has been optimised during the latest three decades to a state-of-the-art technology for treatment of gases containing sulphur compounds as well as for production and regeneration of sulphuric acid.

The WSA technology is characterised by

• meeting the most stringent sulphur emission standards
• production of valuable sulphuric acid and no undesired by-products
• efficient heat recovery
• flexibility and simplicity
• low capital and operating expenses
