Limestone gypsum FGD - Solution - Flue Gas Cleaning -

Wet flue gas desulphurisation is usually based on the use of calcareous absorbents (for example limestone, calcium hydrate, quicklime or chalk). Industrially, the use of limestone as an absorbent has prevailed in the area of power stations. The limestone-gypsum method produces gypsum as an end product, which is marketable for industrial re-use. So-called lime scrubbing reliably removes sulphur ...
