Advantages of Metal Honeycomb SCR

• Stability

  • Strong durability ensures long-term performance.
  • Easy to maintain and repair.
• Efficiency

  • Minimizes catalyst volume with high SV value.
  • Can be installed in a small HRSG space thanks to low catalyst volume.
  • Reduces installation steps by minimizing catalyst volume.
• Technological Innovation

  • Superb catalyst performance makes it possible to remove 90% or more of NOx with smaller amounts of catalyst than those of other existing products.
• Economy

  • The recoated catalyst can be used semi-permanently (more than 30 times).
  • Maintenance costs can be reduced as the catalyst can be reused, and waste is thus reduced.
  • EPC installation costs can be saved as the volume of catalyst is reduced, and weight is also reduced.
• Environmental

  • Features excellent NOx removal rate even during the early period of operation thanks to quick thermal response.
  • Minimizes industrial waste by using metal substrate that can be recycled.
  • Reduces nearby residents complaints by quickly removing the yellow plume.

• Importance of thermal response speed
  • When starting up a gas turbine, a large amount of NO2 is emitted, forming a visible exhaust (the yellow plume). However, the metal honeycomb responds to heat fast, and can thus remove the yellow plume about four-times faster than the existing extrusion-mold catalysts.
