Flue gas desulfurization 🏭(FGD) is a process that removes sulfur dioxide☠️⚠️😷 ((SO_{2})) from the exhaust gases of fossil-fuel power plants, primarily coal-fired ones. This process is crucial for preventing acid rain and reducing air pollution that can lead to respiratory issues. FGD systems achieve this by using chemical reactions, with common methods including wet limestone scrubbing (which produces gypsum), dry sorbent injection, and spray dryer absorption.
