Selective Non-Catalytic Reduction (SNCR)

Selective Non-Catalytic Reduction (SNCR)

Peerless Emissions Control

SNCR systems provide a low-cost technique to reduce NOx emissions by 30%–75% for boilers, furnaces and kilns.

The SNCR process involves injecting a reagent into the flue gas in the appropriate temperature window. The reagent reacts with NOx to form harmless nitrogen and water. The design, arrangement, and location of the reagent injectors are critical to the performance of the SNCR system. Our advanced technology utilizes variable droplet size control and automatic tilting injectors based on furnace temperature, to enhance the NOx reduction performance.

SNCR System Package

Our SNCR systems include reagent storage tanks, pumping and flow control, reagent injection systems, and a boiler control interface. CCA also provides experienced field engineers for optimizing the SNCR in conjunction with the combustion system and overall operations.

Selective Catalytic Reduction (SCR) – Peerless Emissions Control

Selective Catalytic Reduction (SCR) – Peerless Emissions Control

Peerless Emissions Control

As flue gases are combusted in gas turbines and process furnaces, nitrogen oxide (NOx) is formed. Our Selective Catalytic Reduction (SCR) system is a post-combustion NOx control technology, which injects an ammonia (NH3) based reagent into the flue stream to reduce NOx emissions by up to 95%.

Peerless Emissions Control patented Direct Injection SCR System is an innovative delivery, metering and injection system designed to reduce NOx and CO emissions using substantially less auxiliary load compared to a traditional SCR system.

Our Peerless Emissions Control brand TRIM-NOx® XL SCR injection module automatically injects a urea or ammonia-based reagent into the exhaust gas of a boiler, furnace, turbine or IC engine to reduce NOx emissions. Each module is engineered to optimize efficiency, performance and reliability while meeting stringent environmental standards.

Our SCR designs are engineered to optimize efficiency, performance and reliability, while meeting stringent energy standards. They are adaptable for a wide range of temperatures, exhaust flow conditions, and various types of fuel including:

  • Natural Gas
  • Refinery Gas
  • Coal
  • Biomass
  • Fuel Oils

String Wound Cotton Depth Filter Cartridges

String Wound Cotton Depth Filter Cartridges

Mefiag

Mefiag String Wound Cotton Depth Filter Cartridges are fabricated of natural or synthetic fiber wound over a perforated plastic or metal core. The precision winding pattern covers the entire depth of the filter tube with hundreds of funnel-shaped tunnels which become gradually finer from the outer surface to the center of the tube and trap progressively finer particles as the fluid travels to the center. This allows much greater solids retention capacity than is associated with surface filter media of the same dimensions.

Mefiag provides top-quality pumps and filter cartridges for use in several applications. When dealing with corrosive and hazardous chemicals in various industries, experts trust Mefiag filter cartridges to be reliable and efficient as soon as they are installed. Mefiag sets the industry standard when it comes to dependability.

Mefiag products have an excellent reputation. If you need to filter acids, alkalis, or any other hazardous liquids, our cartridge filters will handle the job. The precision winding patterns of our String Wound Cotton Depth Filter Cartridges trap progressively finer particles as the fluids transverse toward the center of the cartridge. Businesses all over the world trust Mefiag cartridge filters.

Substandard filters can leave contaminants behind. Do not rely on inferior cartridges for your filtration needs. Go with Mefiag and get peace of mind. Our expert engineering staff will be there to help you make the right selection. Let Mefiag become a valuable part of your business today.
