Desulfurization of flue gas
WebFlue gas desulfurization (FGD) processes have been widely used since the early 1970's for control of sulfur dioxide emissions from coal-fired power plants. First generation FGD systems employ ''wet processes'' whereby the flue gas is contacted with a solution or slurry of an alkali reagent. Most of these installations use either lime or limestone.
