mix production. For example, 4ue gas desulfurization (FGD)—a technology used to remove sulfur dioxide from the exhaust 4ue gasses of fossil fuel plants—relies on a wet-scrubbing technique using slurry from limestone to scrub the gases. For a typical coal-Lred power plant, FGD will remove 95 percent of the sulfur dioxide in the 4ue gases.

Flue gas desulfurization (FGD) is a very common method for gas claning adopted in a gas processing plant. In this process, the flue gas with acid vapors is scrubbed to remove it as a by-product. Most of the FGD processes use alkali to scrub the flue gas. Many designers of FGD adopt the limestone gypsum process.
