3A Molecular Sieve

NAIKE 3A Molecular Sieve is an alkali metal alumino-silicate; it is the potassium form of the type A crystal structure. Type 3A molecular sieve material 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 maximises lifetime when dehydrating such molecules.

Zeolite 3A Molecular Sieve Applications

Typical Chemical Formula0.45 K2O. 0.55 Na2O. Al2O3 . 2 SiO2. 4.5H2O
SiO2: Al2O3≈2

Typical Application

a) Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadiene)
b) Cracked Gas Drying
c) Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.
e) Drying of liquid alcohol
f) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.
g) Drying of CNG.
