Use of Waste Materials to Augment Lime's Reactivity towards Flue Gas Desulfurization. Paul Maina . Abstract: ... All materials were sourced in South Africa. Natural limestone was mined in the country while fly ash and bottom ash were provided by South Africa electric power producer (ESKOM).
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.

Slaked lime has several different common names depending on its particular use. As construction lime, builders use the material to plaster walls and to stabilize road beds. Cooks know the product as pickling lime due to its use in canning. However, the steel industry uses the most slaked lime for the removal of impurities from their product.
Lime reactivity was improved by blending it with either fly ash, bottom ash or waste activated sludge (W.A.S). The reactivity was tested using a pH-stat apparatus which simulates wet flue gas desulfurization (FGD). Temperature, solid to liquid ratio and stirring speed were varied in addition to lime to additive ratio in optimization tests.
Flue Gas Desulfurization. Application. Wet flue gas desulfurization or scrubber systems are an excellent way of reducing the sulfur dioxide emissions caused by coal combustion boilers. The flue gas discharged from the boiler is fed into the absorber. In the absorber, a mixture of water and pulverized limestone is sprayed on the flue gas.
