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 maximize lifetime when dehydrating such molecules.
Typical Application
- Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien) - Cracked Gas Drying
- Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.
- Drying of highly polar compounds, such as methanol and ethanol - Drying of liquid alcohol
- Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.
- Drying of refrigerants
