KLeeNscrub™ Removes Mercury from Flue Gas

KLeeNscrub™ is a suite of organosulfide-based additives formulated by EES to support MATS compliance. KLeeNscrub™ provides a highly efficient and cost-effective solution for coal fired power plants struggling with emissions of mercury and other metals, such as lead, copper and cadmium, often found in power plant wastewater. KLeeNscrub™ additives are injected into make-up or recirculating absorber slurry within wet flue gas desulfurization (FGD) systems where they react with these metals to form complex compounds that are easily precipitated and removed with the FGD solids.

KLeeNscrub™ has proven its effectiveness in reducing overall Hg levels at the stack exit when burning any type of coal in a variety of scrubber conditions. Further, since KLeeNscrub™ reagents react with mercury to form stable precipitates, mercury re-emission from the reduction of ionic mercury (Hg++) back to elemental mercury (Hg0) is avoided.

Key Benefits

• Highly efficient sulfur-based reagents precipitate dissolved mercury, preventing mercury re-emission
• Mercury control utilizing FGD capture is extremely economical as compared to most activated carbon injection approaches
• Large, stable precipitant is easily removed, passes toxicity characteristic leaching procedure (TCLP) protocols, is thermally stable and is suitable for wall board manufacture
• EES can formulate KLeeNscrub™ additive packages to customize mercury partitioning and solids handling
• Captures additional metals, such as lead, copper, thallium, cobalt, cadmium, nickel, zinc, iron, silver, and tin
• Reagents are non-corrosive, non-hazardous, and manufactured in the USA
