Tip the scales with the new VK38+ catalyst

Selecting the right catalysts for a SO2 converter has always been about balancing expenses and gains. VK38+ helps create that balance - and more.

  • Increase production or reduce emissions without new equipment or expensive premium catalysts
  • Reduce long-term spending on catalysts and get a payback time of only a few months
  • Utilize it in all beds to lower energy consumption, increase catalyst lifetime, and more

“After installing VK38+ in bed 2 the temperature increase is higher than ever. Together with a top up of bed 1, the VK38+ has increased conversion to a point where there's hardly any SO left for beds 3-5 to convert.”

lowering of catalyst waste and raw materials use
reduction of long-term spending on catalysts

What tipping the scales means for your business

Sulfuric acid plants are faced with the ultimate balancing act; how to comply with local regulations while maintaining productivity and limiting costs?
Decreasing capacity and rebuilding existing plants are two options for staying compliant, but these are costly and ineffective solutions. With V38+, it’s a different story.

Sustainable, powerful, cost-effective

With this groundbreaking new catalyst, you can reduce emissions and increase production without making costly investments.

Depending on how you choose to utilize them, VK38+ catalysts can decrease pressure drop, boost production, decrease energy consumption, increase catalyst lifetime by up to 80%, and/or lower emissions. No matter your strategy, you will get better performance using fewer catalysts.

Leverage the industry’s largest range of catalysts

In the 1980s, sulfuric acid catalysts were widely considered fully developed. Ever since, we have kept on developing them.

Today, we offer the industry’s largest range, including dust-protection, cesium-promoted, and LEAP5™ options. This means that we can help you find the precise loading strategy that meets your needs at the lowest cost possible.
