Pronunciation: [ˌɛfd͡ʒˌiːdˈiː] (IPA) 
The acronym FGD stands for Flue Gas Desulfurization, a technology used to remove sulfur dioxide from waste gases produced by combustion. The phonetic transcription of FGD is /ɛf dʒi di/, with an "ef" sound at the beginning, followed by a "jee" sound and then a "dee" sound. This spelling is common in engineering and environmental sciences. FGD is an important process for reducing air pollution and improving air quality around the world.
FGD stands for Flue Gas Desulfurization. It is a technology used in industrial applications to remove sulfur dioxide (SO2) from flue gases emitted by combustion processes.
Flue gas, generated during the combustion of fossil fuels such as coal, oil, or gas, contains pollutants including sulfur dioxide. FGD is a process designed to tackle the environmental issue of SO2 emissions by scrubbing or removing this harmful gas before it is released into the atmosphere. The primary objective of FGD is to reduce the amount of sulfur dioxide, a major contributor to acid rain and air pollution.
The FGD process employs various techniques to remove the sulfur dioxide present in the flue gas. One common method is wet scrubbing, which involves the use of a liquid absorbent that reacts with the SO2 to form a byproduct that can be easily removed from the flue gas stream. This liquid absorbent is often an alkaline solution such as calcium carbonate or sodium hydroxide. Other techniques include dry scrubbing using powdered sorbents or injection of reactants directly into the flue gas.
FGD systems are typically installed in large industrial facilities such as power plants, cement factories, and chemical plants. These systems help these industries meet environmental regulations and minimize their impact on air quality. Furthermore, FGD technology plays a crucial role in reducing the harmful effects of sulfur dioxide on human health, ecosystems, and infrastructure.
