The below whitepaper was written for our client Cormetech after thoroughly reviewing all the materials provided by them. This paper gets into the impact of new air emission rules, including the Mercury and Air Toxics Standards (MATS), which aim to limit mercury (Hg) emissions from coal-fired power plants.

Using the benefits of SCR Hg oxidation and FGD Hg collection is a cost-effective way for plant owners to meet these regulations. SCR (Selective Catalytic Reduction) technology is mainly used for NOx removal. It also helps converting elemental mercury (Hg0) into its oxidized form (Hg2+), which is water-soluble, and it can also be captured by wet FGD systems.

The Minamata Convention was signed by 140 nations in 2013, it represents a global effort to control mercury emissions. This combined method of using existing equipment—optimizing SCR catalysts and enhancing FGD technologies—provides significant cost savings and efficiency. Recent advancements, such as Cormetech’s COMET technology, ensure effective mercury oxidation without affecting NOx removal rates. This approach reduces the need for expensive retrofits and long plant downtimes, making it an appealing option for coal-fired power plants worldwide.
