The Claus and other advanced process solutions for sulfur recovery involve using thermal and catalytic reactions. Sulfur recovery can range from 95% up to 98% depending on the feed and number of reactors used.
Promoting the Claus reaction kinetic while avoiding pore blockage in the catalyst is key to sulfur recovery maximization. Axens aluminas provide first-class performance thanks to their optimized properties. When dealing with residual COS and CS2 species, titanium-based catalysts, used alone or in combination with aluminas, is the solution of choice to reach outstanding performances.
