WET FGD
Our installations include more than 150 WFGD systems in 22 countries and include units firing coal, oil, waste tires and heavy residuals containing up to 7% sulfur. By offering Open Spray Towers, MET installations experience greater reliability by minimizing pressure drop caused by scaling or plugging on internal surfaces. MET offers multiple technologies to remove SO₂ from flue gas, including Limestone, Ammonium Sulfate, Lime, and Sodium Hydroxide. We also offer engineering studies and upgrades on existing units, no matter the OEM.
Technologies
Ammonium Sulfate / Ammonia-based FGD
MET ammonia-based wet FGD captures SO₂ and converts it into ammonium sulfate fertilizer. Explore the process, operating benefits and technical brochure.
Ammonium Sulfate / Ammonia-based FGD
Limestone
Explore MET limestone wet FGD systems for SO₂ removal, using open spray towers and forced oxidation to produce gypsum for agricultural and building uses.
Limestone
Lime WFGD
Explore MET lime wet FGD technology for SO₂ removal, with a highly reactive reagent, low liquid-to-gas ratios and options for producing saleable gypsum.
Lime WFGD
Sodium Hydroxide
MET sodium hydroxide wet scrubbers absorb SO₂ into a dissolved solution without solid waste. Explore sodium scrubbing chemistry and engineering support.
Sodium Hydroxide
DRY FGD
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
SCR
MET is aligned with Termokimik Corporation (TKC), a leading Italian engineering and contracting company, to provide TKC’s proven Selective Catalytic reduction (SCR) technology and worldwide experience exclusively to the North American market. TKC’s demonstrated SCR technology, which has a solid installation base around the world, including 4,000 megawatts in the United States, reduces more than 90% of nitrogen oxides from flue gas emissions.
