Highly porous hydrated lime with strong removal performance

Sorbacal® SP is an enhanced hydrated lime especially designed for DSI applications.  

Technical information


Its specific surface area of typically 40 m2/g (BET) is two times higher than standard hydrated lime, and its porous volume is typically 0.20 cm³/g (BJH), compared to 0.08 cm³/g for standard hydrated lime.  

These qualities make the material significantly more effective for acid gas removal than standard hydrates. The particle size of Sorbacal® SP is designed for optimal reactivity, flow ability and handling.  

A flagship product with a long history of industrial application, Sorbacal® SP is a dry, white, ready-to-use powder. Therefore, no milling or preparation is required before injection. It is ideally suited for all kinds of industrial processes, including incinerators and biomass-fueled power plants, as well as a growing number of new FGT applications in the cement and glass industries.
