NOx and NH3 Catalytic Filter Bags
Overview
1
Upgrade your baghouse to an SCR
2

Based on more than 15 years of experience in catalytic filtration, Gore has developed a completely new approach to the reduction of NOx and ammonia.

With GORE® DeNOx Catalytic Filter Bags you can
  • upgrade your baghouse to an SCR
  • for NOx and NH3 reduction
  • at a much lower investment cost than for an SCR tower
Use your existing baghouse - simply change the filter bags.
2
  • Low capital investment for new equipment
  • Minor changes to process and operation
  • No additional footprint
  • No differential pressure increase
  • Easy to install. Easy to maintain.

  • Simplify flue gas treatment line
  • Save energy costs
  • Reduce capital investment cost
The Challenge of NOx and NH3 Compliance
1

Meeting the latest NOx and NH3 compliance requirements can be difficult and costly.

  • SNCR: often not able to achieve low enough levels of NOx and NH3 at the same time.
  • SCR tower: comes with significant investment cost, especially for existing facilities; limitations in terms of floorspace, overhead clearance, ID fan capacity and other unexpected impacts. Retrofitting an SCR to an existing facility typically requires 30-50 % higher investment than an SCR purchased with the initial plant construction
Full compliance. Less costs.

Gore has developed a dual-function filter bag that simultaneously provides best-in-class particulate filtration and high-efficiency NOx reduction. The Gore technology combines an ePTFE membrane for particulate removal with a PTFE-based catalytic felt for simultaneous reduction of NOx and NH3. Because the GORE Membrane effectively traps dirt and dust, it also protects the catalyst and extends its performance-life.

Proven Technology

GORE DeNOx Catalytic Filter Bags have been proven at full scale references. The conversion is simple.

  • Typically, no new equipment is required, with exception of the installation of new filter bags
  • Minor operating procedures changes
  • Gore applications engineers to assist in the modification, installation and startup of the process
