3A Molecular Sieve

Molecular sieve 3A, also called zeolite 3A or zeolith 3A, is one type of aluminosilicate crystal with average pores measuring of 3 angstrom (0.3 nm). Molecular with kinetic diameter larger than 3 angstrom will be adsorbed by zeolite 3A, otherwise be excluded.

Zeolite 3A molecular sieves are typically used for agents drying or pull out moisture from products. Our 3A molecular sieves are usually used for ethanol dehydration, natual gas dehydration, cracked gas dehydration and refrigerant dehydration.

Storage
As an adsorbent, molecular sieve should not be left exposed to open air and should be stored in dry conditions with air-proof packaging. This product should not be exposed to temperatures exceeding 230˚C (450˚F).

Regeneration
Molecular sieve 3A can be regenerated or activated either thermal regeneration method(Thermal Swing Adsorption, TSA); To remove moisture from a 3A molecular sieve, a temperature of 200-230°C (390-570°F)is required. Molecular sieve 3A can also be regnerated or activated by lowering the pressure in the case of pressure swing processes (PSA). A properly regenerated or activated molecular sieve can give moisture dew points below -100°C. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.
