Calgon Carbon Granted Fifth Patent For Advanced FLUEPAC® Technology Calgon Carbon Corporation (NYSE: CCC), the leader in innovative activated carbon products for flue gas treatment, today announced that the United States Patent & Trademark Office (U.S. P&TO) granted the company its fifth patent related to its FLUEPAC® technology. U.S. Patent, No. 8,450,238 was issued on May 28, 2013, and relates to its FLUEPAC® ST and FLUEPAC® STF products for flue gas treatment. The patent includes claims directed to both composition of matter and methods of manufacture of these products.
The FLUEPAC® ST and STF products excel in removing mercury from systems where acid gases, such as SO3, are present. These products enable coal fired power plants to meet the U.S. Environmental Protection Agency’s Mercury & Air Toxics (MATS) standards using 50% to 70% less activated carbon than other commercially available flue gas adsorbents. Calgon Carbon’s unique carbon additives reduce the detrimental effect of acids in the flue gas without producing the negative effects of other adsorption agents. Combined with ultra-fine adsorbent particles, this technology substantially improves performance and cost effectiveness of mercury removal using the ST product line.

This is the fifth patent granted in the United States related to the FLUEPAC® product line. The other patents are U.S. Patent Nos. 8,057,576, 8,216,535, 8,309,046, and 8,409,330. Each of these patents relate to compositions, methods for using, and methods of manufacture for high performance materials useful in flue gas treatment for mercury. Calgon Carbon also has patents of similar scope pending and issued around the world.

Bill Zinsser, Vice President, Specialty Products of Calgon Carbon, commented, “Calgon Carbon has a long history of innovation in activated carbon technology, and we are extremely pleased with the issuance of this patent. We appreciate the continuing recognition by the United States Patent & Trademark Office, and other patent offices around the world, for our unique contributions to the development of the mercury removal market. We recognize the special needs of our electric utility customers and have made a significant investment in delivering superior products that provide added value to our customers.”
