Product Description

Product Description

Molecular Sieve type 3A is an alkali metal alumino-silicate; it is the potassium form of the type A crystal structure. Type 3A 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.

Typical Chemical Formula

0.4K2O . 0.6Na2O. AI2O3 . 2SiO2 . 4.5 H2O SiO2: AI2O3~2

Typical Application

1. Drying of unsaturated hydrocarbons(e.g. ethylene,propy-lene, butadien) 2. Cracked Gas Drying 3. Drying of natural-gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.  4. Drying of highly polar compounds,such as me-thanol and ethanol  5. Drying of liquid alcohol 6. Static,(non-regenerative) dehydration of insulating glass units,whether air filled or gas-filled. 7. Drying of CNG.
