ARC-A 4mm Impregnated Coal Columnar Carbon – Ammonia & Amine Removal

Key Features

• Acid-impregnated formulation for targeted alkaline gas capture

  Chemically active surface sites react with ammonia and organic amines to form stable salts, delivering far higher removal capacity than standard physical adsorption alone for alkaline odors.

• High-strength 4mm extruded coal base

  90% abrasion resistance minimizes particle breakage and fine dust generation under continuous airflow, reducing downstream filter maintenance and media loss.

• High-activity base carbon performance

  Base carbon delivers >60% CTC value and >900 m²/g BET surface area, providing concurrent adsorption of co-existing VOCs and organic odor compounds.

• Tight particle size distribution

  Over 95% of particles are larger than 6 mesh (3.35 mm), preventing channeling and ensuring uniform gas flow across the entire filter bed.

• Multiple size options for system flexibility

  Available in 4mm, 3mm, 2mm extruded cylinders and 4×10 mesh granular form to match different airflow rates, vessel sizes and pressure drop requirements.

Applications

• Ammonia Breakthrough in Fertilizer Production: Fertilizer plants vent ammonia and organic amines at concentrations that standard activated carbon cannot reliably capture. ARC-A's phosphoric acid-impregnated surface chemisorbs alkaline nitrogen compounds at low concentrations, converting ammonia into stable bound species rather than relying on reversible physical adsorption.

• Wastewater Stripping Exhaust Treatment: Aeration and sludge stripping systems release ammonia and putrid odors. ARC-A's acid-impregnated active sites react with alkaline gases to form stable salts, delivering removal capacity where untreated carbon would rapidly saturate.

• Poultry & Livestock Farm Odor Control: Enclosed animal housing accumulates ammonia that irritates workers and animals. ARC-A's chemisorption mechanism captures ammonia at typical agricultural facility levels, improving indoor air quality beyond what physical adsorption alone can achieve.

• Chemical Processing Amine Abatement: Facilities handling amine-based raw materials and intermediates face low-concentration alkaline vapor challenges. ARC-A's acidic surface chemistry targets amine molecules that weakly adsorb on standard carbon, providing dedicated alkaline gas control.

Technical Advantages

• Dual mechanism of physical adsorption plus chemical neutralization delivers higher ammonia capacity than untreated granular carbon for alkaline gas streams.

• High-strength 4mm extruded coal base minimizes particle breakage and fine dust generation under continuous airflow.

• Tight particle size distribution prevents channeling and ensures uniform gas flow across the filter bed.

• All production batches tested to GB/T 7702-2008 standards for consistent quality and predictable breakthrough performance.

FAQ

Q: What is the difference between ARC-A and ARC-AL?

A: ARC-A uses a higher-activity base carbon with stronger adsorption capacity, making it the preferred choice for moderately loaded industrial exhaust streams requiring longer service life. ARC-AL is the economy grade with balanced performance, suitable for light-load ambient odor control where total project cost is the primary consideration.

Q: Can ARC-A treat hydrogen sulfide and acidic odors?

A: ARC-A is formulated specifically for ammonia and alkaline amine odors. For hydrogen sulfide and acidic gas treatment, we recommend SRC-A impregnated activated carbon. For mixed odor streams, the two grades can be arranged in separate bed layers.

Q: How often should ARC-A be replaced?

A: Under typical low-concentration ammonia loading, expected service life ranges from 6 to 12 months. Actual replacement timing should be determined by monitoring outlet ammonia concentration and bed pressure drop.
