- Synonym: Zeolite 4A, 4A-DG, ZEOCHEM® Z4-04, BASF 4A Molecular Sieve, SYLOBEAD® MS 512, SYLOBEAD® MS 514.
- Typical Chemical Formula: Na2O.Al2O3.2SiO2.4,5H2O
- CAS NO.: 1318-02-1
Cryogenic plants and Natural gas dehydration plants utilize 4A DG molecular sieves to protect downstream equipment by consistently drying natural gas to less than 0.1 ppmv to prevent ice formation and the resulting pressure drop and consistently allowing our customers to meet product specifications over the complete service life of the adsorbent.
