The 1970s saw the development of methods for the effective scrubbing of flue gases from waste incineration. Different techniques are used to remove sulphur, chlorine and fluorine from flue gases before they leave the chimney. This is done by neutralising and precipitating the pollutants using limestone-based products. Achieving optimum results requires the use of pure limestone products.
SMA Mineral produces and supplies a range of products designed for flue gas treatment. The most suitable product depends on the scrubbing method used and the composition of the flue gases.
