Feb 04, 2020 Semi-dry flue gas desulfurization (FGD) technology is used by some coal-based power plants to remove sulfur dioxide from flue gas. In semi-dry FGD systems, SO 2 is removed by calcium-based sorbents in a reactive spray dryer, but the level of desulfurization is lower than in wet FGD systems. This work evaluates the effects of seven additives in the …

Flue gas desulfurization. Flue gas desulfurization (FGD) is the current state-of-the art technology used for removing sulfur dioxide (SO 2) from the exhaust flue gases in power plants that burn coal or oil to produce steam for the steam turbines that drive their electricity generators. Sulfur dioxide is responsible for acid rain formation.

Flue Gas Desulfurization - an overview

Several wet flue gas desulfurization (FGD) processes are based on the absorption of sulfur dioxide in caustic suspension or absorption liquor. The dissolved sulfur dioxide, which we will refer to as S (IV), is neutralized by the additive, commonly lime or limestone [1]. In aqueous phase several species of S (IV), hydrated sulfur dioxide, bisulfite and sulfite are formed according to …

Sulfur dioxide may also be removed by dry desulfurisation by injection limestone slurry into the flue gas before the particle filtration. It is most notable as the product of flue-gas desulfurization. This improvement resulted in part from flue-gas desulfurization, a technology that enables SO 2 to be chemically bound in power plants burning sulfur-containing coal or oil.

The report describes the spray dryer flue gas desulfurization (FGD), which is a throwaway process in which sulfur dioxide (SO2) is removed from flue gas by an atomized lime slurry (Ca (OH)2). The hot flue gas dries the droplets to form a dry waste product, while the absorbent reacts with sulfur dioxide in the flue gas.

This paper presents a mathematical model of the SO/sub 2/ removal process in a spray-dryer flue-gas desulfurization system. Simultaneous evaporation of a slurry droplet and absorption/reaction of SO/sub 2/ in the droplet are described by the corresponding heat- and mass-transfer rate relations. Dissolution kinetics of lime particles within a slurry droplet is …
