NOx and NH3 Catalytic Filter Bags
GORE® DeNOx Catalytic Filter Bags reduce NOx and ammonia to meet strict compliance requirements with minimal or no changes to the existing process and equipment.
Upgrade Your Baghouse to an SCR with Proven NOx and NH3 Reduction
Our catalytic filter bags achieve both NOx reduction and ammonia filtration within your existing baghouse, with no need to do anything more than change your filter bags.
With more than 15 years of experience in catalytic NOx reduction, Gore has developed a completely new approach to NOx control using a NOx removal catalyst within our filter bags. Acting as an SCR without the cost of installing an SCR tower, our specially developed DeNOx process enables you to cut NOx and ammonia emissions, effectively and efficiently.
By using your existing filter bags, with no other equipment changes required, you benefit from:
- 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.
- Reliably meet NOx, NH3 and particulate compliance requirements
With GORE® DeNOx Catalytic Filter Bags you can:
- Upgrade your baghouse to an SCR
- Reduce NOx and NH3
- Significantly lower investment costs compared to installing a SCR tower
GORE DeNOx Catalytic Filter Bags reduce NOx and NH3 across a variety of industries and applications, including:
- Waste-to-Energy
- Chemicals processing
- Lime and cement
- Metals processing
GORE DeNOx Filter Bags are easy to retrofit but also a perfect choice for new plants:
- Simplify flue gas treatment line
- Save energy costs
- Reduce capital investment cost
NOx and NH3 Compliance
Full Compliance. Less Costs.
Meeting the latest NOx and NH3 compliance requirements can be difficult and costly.
- SNCR systems often struggle to achieve low enough levels of NOx and NH3 at the same time, leaving you in danger of non-compliance.
- SCR towers come with significant investment cost, especially for existing facilities. There are also 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.
Our specially designed ammonia filter bags filter NOx and NH3 to deliver the compliance you need at a price you can afford. Our dual-function filter bags simultaneously provide best-in-class particulate filtration and high-efficiency NOx reduction, combining an ePTFE membrane for particulate removal with a PTFE-based catalytic felt for simultaneous reduction of NOx and NH3. Effectively trapping dirt and dust, they also protect the catalyst and extend its performance-life, reducing your total cost of ownership.
Proven Ammonia Filter Bag Technology with NOx Removal Catalyst
Our GORE DeNOx Catalytic Filter Bags have been proven in full scale references around the world. The conversion is simple since no new equipment is required – it’s just a straightforward filter bag change. Some minor operating procedure changes are needed to maximize NOx and NH3 reduction. But we are here at every stage to help you with the modification, installation and start-up of the process.
