MET Offers Unique CDS-FGD Technology


Circulating Fluidized Bed Flue Gas Desulfurization System

Known around the globe for solid and innovative air quality control technologies, MET's advanced circulating dry scrubber flue gas desulfurization (CDS-FGD) system provides the proper chemistry and conditions to simultaneously and effectively absorb sulfur dioxide, acid gases and associated heavy metals. This advanced, multi-pollutant control technology minimizes water consumption, improves reagent usage and produces no waste water streams.


Performance capabilities include:

  • SO2 removal of up to 98+%
  • SO3 removal of up to 98+%
  • HCl / HF removal of up to 98+%
  • Mercury removal of up to 90+%


The MET CDS-FGD technology employs the key design feature Multi-Stage Humidification which injects water separate of the reagent and at multiple levels in the absorber. This element not only promotes high system reliability but also boosts SO2 removal efficiency.

Determining to utilize Wet or Dry FGD technology is dependent upon a variety of factors. MET's Dry CDS-FGD system offers the following advantages over conventional wet FGD technology:


  • lower capital cost
  • less water consumption
  • smaller footprint
  • less by-product disposal
  • operational stability
  • multi-pollutant removal
  • lower power consumption
  • separate control of reagent and water
