Sulfuric acid industry

But the energy transition means essential sulfur supplies from petrochemicals are diminishing. We have the solutions to help you meet demand efficiently while also meeting sustainability and regulatory requirements. 

Topsoe and the sulfuric acid industry

The global sulfuric acid market is booming, driven by increasing demand from industries such as fertilizer production, chemical manufacturing and metal processing.¹ At the same time, a potential shortage of sulfur is looming as the world transitions to a low-carbon economy: a significant amount of global supply currently comes from the desulfurization of fossil fuels. 

That means the sulfuric acid industry is under increasing pressure to make more from less. Over the years, our solutions have helped the industry move forward, in terms of both the production of acid and the regeneration of spent acid, while meeting regulatory requirements.

Adressing your needs

Whether you produce sulfuric acid from elemental sulfur or from SO2 regenerate spent sulfuric acid or clean sulfurous gases, we have the optimal solutions.  

Our high activity catalysts provide high conversion, high energy efficiency, low-pressure drop, and production stability, as well as an exceptionally long life in any sulfuric acid plant. They ensure that you 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. A truly flexible solution, it can remove a wide range of sulfurous compounds from off-gases and waste streams in a string of different applications. It can typically produce sulfuric acid with a 98% concentration.  

If you are dealing with sulfurous or sour off-gases, you can convert them into valuable sulfuric acid or elemental sulfur with our Smarter Sulfur Solutions. These solutions are already in use across several industries, including oil refining and natural gas, viscose, pulp and paper, metallurgy, and carbon black, and continue to evolve and lead the industry in terms of energy efficiency, yield, and environmental impact.
