How to Get Rid of Ammonia (NH₃) and Smell from Air and Gas.
Ammonia (NH₃) is a colorless, low molecular weight gas with a sharp, pungent odor, widely recognized from industrial cleaners and agricultural settings. It is lighter than air and highly soluble in water due to hydrogen bonding, a property it shares with water molecules. This bonding contributes to ammonia’s volatility and its tendency to spread quickly in enclosed environments.
Ammonia is produced or used across various industries particularly in fertilizer manufacturing, cold storage, wastewater treatment, and petrochemical processing. However, when released into air or process gas streams, it poses significant hazards: it is toxic, corrosive, and environmentally harmful.
Impregnated Activated Carbon for Ammonia (NH₃) Removal
In industrial air purification systems, the release of gaseous ammonia (NH₃) can be managed effectively with the use of impregnated activated carbon. These carbons are treated with acidic compounds (such as phosphoric or sulfuric acid) that chemically neutralize ammonia via a simple acid base reaction. The resulting ammonium salts are then stored securely within the pore structure of the carbon.
Unlike untreated carbon, which struggles to retain fast moving ammonia molecules due to their low affinity for standard adsorption sites, acid impregnated carbon overcomes this limitation. The ammonia is not just physically trapped but chemically converted and fixed within the media, making the process highly efficient and stable.
Key advantages include:
- High removal efficiency for ammonia even at low concentrations
- Stable retention through chemical bonding
- Low maintenance with long service intervals
Suitable for ambient temperature operations
Applications:
- HVAC air filters for odor removal
- Wastewater plant ventilation systems
- Industrial exhaust air treatment
- Livestock facilities and poultry farms
3X Molecular Sieve for Ammonia in Dry Gas Streams
For applications involving dry gas purification, such as pre treatment in PSA systems or gas phase separation, 13X molecular sieve is widely used for ammonia removal. Its pore structure (approx. 10 Å) and strong polarity enable it to adsorb ammonia molecules through physical interaction under pressure effectively.
This makes molecular sieves particularly suitable for:
- Closed loop chemical systems
- Process gas purification
- Industrial refrigerant recovery
- Protective gas systems in electronics or pharmaceuticals
Applications:
13X beads are also regenerable at elevated temperatures, supporting multi cycle usage in fixed bed columns.
