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.
