ABSTRACT
After the observation of serious environmental damages resulting from industrial activities, air pollutionreduction has become globally very important.Fuels and flue gas desulfurization methods in power plants are applicable for petroleum derived fuelsconsuming units. But in coal fuel power plants, only Flue Gas Desulfurization (FGD) can be used.Therefore, the substitution of (natural) gas for power plants fuels has become a common way, dueto its low sulfur content and lower excess air requirement. But, for existing power plants and beforechanging their fuels to natural gas, a suitable FGD method should be selected.In this article appropriate power plant FGD methods are studied. Our calculation addresses the dryadsorption method plus (elemental) sulfur production as the most economical one.
