Sulfur Content Requirements For Fgd Systems

Flue Gas Desulfurization(FGD) Market Systems & Services

Hence, there is a constant need for reducing sulfur emissions by regulating industrial emissions, which calls for different technologies for flue gas desulphurization. Flue gas desulfurization (FGD) consists of removing sulfur dioxide from flue gas before it is emitted.

but also create higher flow and pressure drop in the absorber and greater strain on the mechanical systems. Some utilities wish to burn alternative, lower cost coals with a higher sulfur content (well beyond that originally designed for) that promise to further compound the demands on older WFGDs.

Flue Gas Desulfurization (Acid Gas Removal) Systems

Sulfur content - The sulfur content, together with the allowable emission standards, determines the required SO 2 removal efficiency, the FGD system complexity and cost, and also affects sulfite oxidation.

pH Measurement and Installation Technical Paper Guidelines .

U.S. FGD systems handle coals with much higher sulfur content which helps to explain why we are somewhat behind. It is expected that with new installations as well as for ret-rofits forced oxidation will be the process of choice. This will apply to the U.S. as well as most other countries in the world.

Sulfur Dioxide Scrubbers - Air Quality - Duke Energy

An SO 2 scrubber system is the informal name for flue gas desulfurization (FGD) technology, which removes, or "scrubs," SO 2 emissions from the exhaust of coal-fired power plants. A scrubber works by spraying a wet slurry of limestone into a large chamber where the calcium in the limestone reacts with the SO 2 in the flue gas.
