UOP MOLSIV™ 3A EPG Adsorbent
Applications
3A EPG adsorbent is preferred for commercial dehydra- tion of unsaturated hydrocarbon streams, such as cracked gas, ethylene, propylene, and cracked liquid olefins. The small pore size of 3A EPG molecular sieve essentially prevents co-adsorption of hydrocarbons.

Molecules adsorbed: Molecules with an effective diameter of <3 angstroms, e.g., H2O
Molecules excluded: Molecules with an effective diameter >3 angstroms, e.g., C2H4, CO2, and CH3OH
Measured at 17.5 mm Hg and 25 °C. The normal equilibrium water capacity in water saturated gas or liquid hydrocarbon is 22 wt-%.
