Description:

4A-DG is the sodium form of the Type A molecular sieve to adsorb molecules with critical diameters up to 4 angstroms.

Applications:

4A-DG adsorbent has been specially formulated for drying natural gas liquids. It has demonstrated the ability to provide long service life and predictable, economical dehydration service. 4A-DG adsorbent can provide very low moisture levels required by cryogenic NGL recovery plants. It is also used for removing H2S and CO2 from natural gas.

CHEMICAL FORMULA:

Na12(AlO2)12(SiO2)12·xH2O

REGENERATION

4A-DG can be regenerated for re-use by heating with simultaneous purge or by evacuation.
