    Description
    EniSorb 3A Molecular Sieve has an effective pore opening of about 3 angstroms (0.3nm). This is large enough to allow in moisture, but excludes molecules such as unsaturated hydrocarbons which can potentially form polymers; and this maximize lifetime when dehydrating such molecules.

    Application - Drying of unsaturated hydrocarbons (e.g. ethylene, propylene)           
    - Cracked Gas Drying
    - Drying of natural gas, if COS minimization is essential, co-adsorption of hydrocarbons is required                
    - Drying of highly polar compounds, such as methanol and ethanol   
    - Drying of liquid alcohol
    - Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.
