  • Dry Scrubber an overview | ScienceDirect Topics

    Spray dry scrubbers remain the second most widely installed system after wet scrubbers in the coalfired power plants with a total installed capacity of around 25 GWe by the end of 2008 (Zhu, 2010). SO 2 removal efficiencies reach 90–95%, depending upon the sulfur content of coal ( Carpenter, 2012 ).

  • 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.

    In addition, the availability of a wet scrubber system will allow novel methods aimed at enhancing mercury removal in a FGD system to be tested. The goal of the proposed project is to develop a further understanding of the potential to capture toxic trace metal species by wetscrubbing the flue gas generated by the combustion of selected coals.

  • Sulfur Dioxide Scrubbers Air Quality Duke Energy

    A scrubber works by spraying a wet slurry of limestone into a large chamber where the calcium in the limestone reacts with the SO 2 in the flue gas. There are some variations in design of scrubbers. For example, some scrubbers may use other chemicals such as lime or magnesium oxide to react with the SO 2 in the flue gas.
