LEAP5™ catalysts are specifically designed for oxidizing SO₃-strong gases, and are ideal for use in the last passes in single-absorption plants or in the third pass in 3+1 and 3+2 double-absorption plants.

Lower sulfur emissions, greater output or a balance of the two

LEAP5™ catalysts enable you to achieve unprecedented reductions in SO₂ emissions, and make it easy to comply with stringent restrictions – both now and in the future. Using the same catalyst technology, you can also increase production whilst maintaining current levels of SO₂ emissions. Or you can mix the benefits to suit your particular operating setup and market requirements. The choice is yours.

In single-absorption setups

• Up to 55% reduction in SO₂ emissions using LEAP5™ in the 4^th and 5^th passes of a 5-bed plant.
• Up to 99.5% conversion (500 ppm emissions) in a new plant using LEAP5™ in the last two passes

In double-absorption setups

• An additional 30% reduction in SO₂ emissions from existing 3+1 plants that have already installed a cesium–promoted catalyst in the final pass
• New or revamped plants can achieve 20 ppm SO₂ emissions

Benefits:

• Superior catalytic effect because of high fraction of vanadium in the active V⁵⁺ oxidation state
• Significantly better catalytic activity than with standard potassium-promoted and cesium-promoted catalysts
• Ideal for use in converted strong gases across the entire temperature range
• Stronger feed gas makes it possible to reduce overall pressure drop
• Lower chemical consumption in any scrubber unit
