Wet scrubbing of flue gas can reduce flue gas particle loadings to environmentally acceptable loads at reasonable L/G ratios6 The major disadvantage of lime/lime stone wet scrubbing is the large volume of solid waste producedA new wet limestone−gypsum process for flue gas desulfurization FGD has been developed The main difference compared to a conventional wet FGD process is the ability of the new process to utilize granular limestone directly as a desulfurizing reagent

In wet flue gas desulphurisation open spray tower absorbers have prevailed which are divided into two principal zon These are the absorption zone exposed to the flue gas and the absorber sump in which the limestone slurry is trapped and collectedConventional wet process systems for flue gas desulfurization use an aqueous slurry of limestone CaCO 3 as the reagent in an absorber or scrubber which is usually a vertical vessel in which the flue gas is contacted with the slurry
