3A molecular sieve

Professional manufacturer and export for Molecular Sieves 3ATypical for Methanol and Ethanol drying

Molecular Sieve 3A is an alkali metal alumino-silicat , it is the potassium form of the type A crystal structure . Type 3A has an effective pore opening of about 3 angstroms (0.3mm) . This is large enough to allow in moisture , but excludes molecules such as unsaturated hydrocarbons which can potentially form polymers , and the maximizes lifetime when dehydrating such molecules .

Typical Application

a, Dry of unsaturated hydrocarbons ( ethylene , propylene etc )

b, Cracked gas drying

c, Drying of natural gas , if COS minimization is essential , or a minimum co-adsorption of hydrocarbons is required

d, Drying of highly polar compounds , such like methanol and ethanol

e, Drying of liquid alcohol

f, Static , (non-regenerative ) dehydration of insulating glass units , whether air filled or gas filled

g, Drying of refrigerants

Typical Chemical Formula

0.45K20. 0.55Na2O . Al203. 2SiO2. 4.5H2O

SiO2:Al2O3≈2
