Flue Gas Desulfurization Products Use on Agricultural Land Use Systems

Abstract

The Flue gas desulfurization (FGD) process is a set of technology that is used to remove the sulphur dioxide (SO2) present in the flue gas, which is exhausted from the thermal power plant during electricity generation. In FGD equipment, high calcium-containing sorbent materials are sprayed, which will react with the SO2 present in the flue gas and result in the formation of calcium sulphite and FGD gypsum etc. these formed waste materials are known as FGD products. The FGD products can be used in agricultural land for the amelioration of the soil acidity, salinity and alkalinity, it improves the soil’s physical property, reduce the runoff rate etc. Now a day around two per cent of generated FGD products is used in the agricultural field. As some of the FGD products may contain heavy metals, their direct use in the agriculture field may cause environmental hazards. To avoid environmental pollution before its direct use the chemical properties of the product have to be thoroughly checked. So by the use of these materials in the agricultural field, we can effectively convert waste material into useful products.
