Flue gas desulfurization (FGD) systems have been in existence in the United States for only 17 years but they have made a tremendous impact in the operation of utility plants. At present, almost 60,000 megawatts (MW) of power are treated by FGD systems with estimates on future use hinging on any new acid rain legislation. The costs of those systems are high, but recent developments in dry scrubbing techniques may change the direction for FGD toward these more cost effective systems.
