Dry Flue Gas Desulfurization (FGD) : Unlike WFGD, DFGD does not involve the use of liquid reagents. Instead, a dry sorbent, such as hydrated lime or sodium bicarbonate, is injected into the flue gas stream. The sorbent reacts with sulfur dioxide to form solid byproducts, which are collected using particulate control devices. DFGD is suitable for applications with lower gas flow rates and lower sulfur dioxide concentrations. Semi-Dry Flue Gas Desulfurization: This technique combines elements of both wet and dry processes.
A spray dryer is used to introduce a fine mist of reagent into the flue gas, creating a humid environment. The reaction between the reagent and sulfur dioxide occurs in the dryer, forming a dry powder that can be collected using fabric filters or electrostatic precipitators. The widespread adoption of FGD technologies has yielded numerous benefits for industries and society as a whole: Reduced SO2 emissions: Flue Gas Desulfurization (FGD) systems have proven to be highly effective in reducing sulfur dioxide emissions by up to 90% or more. This reduction significantly improves air quality, reduces the risk of acid rain formation, and minimizes the associated environmental and health impacts.

3 February 2020 - Global Flue Gas Desulfurization Market is expected to reach USD 23.69 billion by 2020.
Sulphur present in the coal after reaction forms Sulphur dioxide (SO2) that is toxic to the atmosphere.
To save environment form such toxins, various countries like European and the U.S. countries have strict policy regarding the discharge of Sulphur dioxide that should be less than 0.05%.
Therefore, power plants are installing Flue Gas Desulfurization (FGD) plant or unit mainly to lower the Sulphur dioxide in environment.The Market is estimated to grow at a significant CAGR of 6.0% over the future period as the scope and its applications are rising enormously across the globe.
Rising use of coal for electricity generation all over the world, presence of several air pollution control rules, and growing awareness regarding environment safety are documented as major factors of Flue Gas Desulfurization Market that are estimated to enhance the growth in the years to come.
Wet Flue Gas Desulfurization System sector comprise of seawater, limestone, and others.
