WSA - turn sulfurous emissions into commercial opportunities
With our well-proven WSA (Wet gas Sulfuric Acid) technology, you can turn your sulfurous gases into commercial-grade sulfuric acid.Download
With our well-proven WSA (Wet gas Sulfuric Acid) technology, you can turn your sulfurous gasses into commercial-grade sulfuric acid (typically 98% concentration) and generate high-pressure superheated steam for use elsewhere.
A flexible, reliable trouble-solver
Able to remove a wide range of sulfurous compounds from off-gases and waste streams in a string of different applications, WSA is a truly flexible solution. You can use it to keep emissions from your key processes compliant, with the possibility of more than 99.9% sulfur removal efficiencies.
Recycling or recovering more than 90% of the feed streams' energy content and exporting the excess in the form of high-pressure superheated steam, WSA technology is truly climate- friendly. And with limited capital expenditure and low operating costs, it provides you with a reliable path to low lifecycle costs.
Overall, the TOPSOE™ WSA technology helps you stay compliant while limiting overall operating costs, reducing risks, and strengthening your operation's environmental profile. That's why it has achieved more than 40 years of well-documented commercial success in numerous operations worldwide.
The WSA process
How it works
WSA is a wet gas catalytic process that eliminates the energy waste and waste water production associated with drying the process gas. Here’s how it works:
