Wet FGD

MET offers our patented ALRD™ Technology with most WFGD installations. This commercially demonstrated device abates flue gas sneakage and re-entrains slurry – ultimately increasing liquid to gas contact and SO₂ removal efficiency by eliminating uneven spray density. By positioning ALRDs below selected spray levels, flue gas sneakage and any wall-clinging slurry is redirected into the spray zones, dramatically improving SO₂ removal performance.

We’ll be happy to discuss your system and tailor a solution that is right for you.
