New Wet FGD Process Using Granular Limestone

17/05/2002A new wet limestonegypsum 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. Thus the pulverizing of limestone which causes power consumption can be avoided. The performance of the wet FGD process
