Mineral Wool Industry

Efficient SOx cleaning

Mineral wool producers use SOLVAir® bicarbonate solution to economically mitigate their flue gas emissions.

Mineral wool is today one of the most performing insulating materials and greatly contributes to save energy and cost of heating. 

Volcanic stones are melted with some additives, then extruded and spun to stone wool. The minerals contain some sulfur emitted as sulfur oxides (SOx). 

The SOLVAir® Solution: dry sorbent injection of sodium bicarbonate for flue gas cleaning

Treating SOx in a double filtration step with sodium bicarbonate solution allows the compliance with the most stringent emission limit value (ELV) and at the same time minimizes the residual production.
