• Flue Gas Desulfurization (FGD) Wastewater

    One of the most commonly used flue gas desulfurization (FGD) technologies for scrubbing pollutants from power plant gas emissions is a wet scrubber system. In this process, many pollutants end up in the circulating water in the scrubber. To maintain appropriate operating conditions, a constant purge stream is discharged from the scrubber system.

  • FlueGas Desulfurization ("Scrubbers")

    The fact that some significant portion of the SO2 in the liquid turns into another chemical, namely HSO3 –, makes more room for SO. 2 in the liquid and consequently promotes a greater suction of SO2 from gas to liquid. When properly dosed, the limestone slurry is able to hold 6 .

  • Determination of Flue Gas Desulfurization in a Power Plant ...

    A flue gas desulfurization (FGD) processing unit, generally known as a scrubber, eliminates sulfur dioxide (SO 2) from the exhaust flue gases in power plants in which coal is burnt. Airborne SO 2 forms sulfuric acid (H 2 SO 4 ) by oxidizing within airborne water droplets, resulting in "acid rain".

    During the combustion process the sulfur in the coal combines with oxygen in the air to form SO 2. To remove the SO 2, the flue exhaust gases from a coalfired power plant are commonly led through a spray of limestone slurry in a socalled scrubber. The resultant reaction typically captures 90% or more of the SO 2. Approximately 8085%
