Desiccant 3A-EPG

Description:

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

Applications:

3A-EPG is preferred for dehydration of unsaturated hydrocarbon streams, such as cracked gas, ethylene, and cracked liquid olefins. The small pore size of 3A-EPG adsorbent essentially prevents co-adsorption of hydrocarbons.

CHEMICAL FORMULA:

K12(AlO2)12(SiO2)12·xH2O

REGENERATION

3A-EPG can be regenerated for re-use by heating with simultaneous purge or by evacuation.
