O,.Its effective aperture is 3 eh, mainly used for absorbed water(the diameter of water molecules is about 2.8 eh), not adsorb any molecular diameter greater than the water and thus play a role in screening, With the adsorption rate was fast, regeneration frequency ,more crash-resistant, high strength and Strong anti-pollution ability, adsorption efficiency and long life for high-end sector of choice for high-precision dry moisture products, Control of the cavity insulating glass has long maintained at the dew point below -60 centigrade.

Molecular sieve 3A is used for commercial dehydration of unsaturated hydrocarbon streams as cracked gas,acetylene,propylene,and butadiene.It is also used for dehydration of alcohol and solvents.

Key Words
Under the ultra-low humidity conditions,still offer high water adsorbption capacity,Effective control of environmental humidity
Have a choice of gas adsorption, only the absorption of a diameter less than 3 angstrom molecular, mainly for the absorption of water molecules

Typical Application
1) Drying of unsaturated hydrocarbons(e.g.. ethylene,propylene,butadien)
2) Cracked Gas Drying
3) Drying of natural gas,if COS minimization is essential,or a minimum co-adsorption of hydrocarbons is required.
4) Drying of highly polar compounds,such as methanol and ethanol
5) Drying of liquid alcohol
6) Static,(non-regenerative) dehydration of insulating glass units,whether air filled or gas-filled.
7) Drying of refrigerants

3A-Zeolites are available in beads of 1-2mm(10*18mesh),2-3mm(8*12mesh),2.5-5mm(4*8mesh)and as powder,and in pellet1.63.2
