In the United States, the 1990 Clean Air Act Amendments caused many power plants to switch to low-sulfur coal or to install flue-gas desulfurization units (FGD units, or scrubbers). Subsequent tightening of sulfur dioxide (SO2) regulations has caused more plants to scrub their emissions.
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.

A multistage production process is necessary to transform the SO 2 in flue gas, into panel-grade FGD gypsum that will meet the precise specifications of gypsum panel manufacturers. As flue gas is generated, it is passed through an electrostatic precipitator that separates fine particles, including fly ash, from the gas.
flue gas treatment, a process designed to reduce the amount of pollutants emitted from the burning of fossil fuels at an industrial facility, a power plant, or another source. Flue gas—the emitted material produced when fossil fuels such as coal, oil, natural gas, or wood are burned for heat or power—may contain pollutants such as particulates, sulfur dioxide, …
