Applications: Boilers, Turbines, HRSG, Stationary Diesel, Marine, Refinery and Chemical Processing Whether solid, liquid, or gaseous fuels, optimizing SCR catalyst design is a key to high performing and beneficial emission control systems. For natural gas-fired applications, utilizing advanced catalyst and module designs are able to deliver increased catalytic multi-pollutant potential, reduced pressure losses, and reduced…

The ability to improve turbine efficiency while reducing ammonia usage, expanding operating load range, and lowering maintenance costs are hallmarks of a well-designed SCR system. Advanced catalyst and module designs are able to deliver increased catalytic potential, reduced pressure losses, and reduced maintenance needs. The additional catalyst potential can be leveraged for higher NOx reduction,…

The process of utilizing coal as a fuel source to generate electricity produces residual ash.  Depending upon the type of coal, this ash can be beneficial as an additional revenue stream for use as a supplemental material in concrete or gypsum panel products.  However, the fly ash can also be a detriment to downstream air…

Current market trends and regulations are dictating energy production where SCR catalyst are being challenged to operate with flexibility, at lower temperatures / lower loads, and having the ability to operate at utmost efficiency in order to reduce NOx emissions. Operational strategies are part of an experienced SCR Catalyst Management Plan supplemented by testing and reporting on the…

SCR systems today are being challenged to operate with more flexibility and at much lower temperature ranges for the reduction of NOx emissions due to low load operational strategies. Renewable energy  assets are taking priority in many areas creating a dynamic whereby coal and gas fired plants are not operating as the base load and…

As combustion turbines become more highly utilized to meet power generation needs, the demand for reliable performance across a wide variety of operating conditions is critical. See how 米6体育 METEOR™ technology can help assure multi pollutant environmental compliance across a wider load range, while achieving enhanced operational efficiency and lower maintenance cost. METEOR™, an Advanced…

The U.S. refinery industry has spent billions of dollars since 1990 to comply with federal environmental regulations.  Increased scrutiny to reduce emissions associated with NOx, NH3 slip, and SO2 oxidation has significantly added to the costs of manufacturing refined products.  Applying effective SCR Catalyst best practices can increase catalyst life, reliability, and performance while decreasing total emissions…

Power producers are increasing the asset utilization of their gas fired Combined Cycle and Simple Cycle units.  Increased load cycling and operating hours brings added challenges to meeting NOx and CO limits.  Simple Gas Catalyst Management strategies can optimize Gas asset performance and decrease the Total Life Cycle costs of the SCR system. Terry McTernan,…

The Mercury and Air Toxics Standards (MATS) rule requires all power plants to reduce hazardous air pollutants, including mercury.  Power plants are the largest source of several toxic air pollutants and are responsible for 50% of the Mercury emissions in the United States.  Even though half the power plants in the US are equipped with…
