3A / 4A / 5A / 13X Molecular Sieve Pellets for Natural Gas Drying

Product Description

Product Description

Molecular Sieves

The 3A, 4A, 5A and 13X molecular sieve pellets are premium adsorbents engineered for efficient natural gas drying and purification. Featuring high adsorption capacity, low attrition rate, excellent mechanical strength and stable performance, they effectively remove moisture, CO2, H2S and other impurities to meet strict industrial standards. With uniform particle size and good thermal stability, they are ideal for pressure swing adsorption and temperature swing adsorption systems, lowering dew point effectively and preventing hydrate formation. Widely applied in natural gas transmission, LNG plants, petrochemical and gas processing industries, these molecular sieves protect pipelines, valves and downstream equipment, ensuring safe, stable and long-term operation. We offer consistent quality, reliable supply and customizable specifications to satisfy various industrial drying and separation requirements.

Adsorption Mechanism

Size Exclusion: Molecules smaller than pore size (e.g., H2O: 2.6 Å) enter and adsorb; larger ones (e.g., CH4: 3.8 Å) are blocked.
Surface Interactions: Polar molecules (e.g., water, NH3) bind strongly via hydrogen bonding and electrostatic forces.
Thermodynamics: Exothermic process; adsorption capacity decreases with temperature.

Application

widely Applied

 
Gas Dehydration & Purification: Remove moisture from natural gas, compressed air, refrigerants, and industrial gases to prevent corrosion and icing.
