Molecular Sieve 3a

3A adsorbent, a potassium-exchanged form of the type A molecular sieve, is an alkali metal aluminosilicate. 3A adsorbent will adsorb molecules with critical diameters up to 3 angstroms type.

APPLICATIONS

-          3A adsorbent is preferred for commercial dehydration of unsaturated hydrocarbon streams, such as cracked gas, ethylene, propylene, and cracked liquid olefins.

-          Drying of polar liquids (methanol, ethanol, and hydroxide organic compound ).

-          Drying refrigerants.

-          Drying N₂-H₂ mixtures made by cracking of NH_3.
