Product details:

Molecular Sieve 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 (0.3 nm). This size is large enough to allow in moisture, but excludes molecules such as unsaturated hydrocarbons which can potentially form polymers; and this maximizes lifetime when dehydrating such molecules.

Molecular Sieve Product Options and Choices: 4 to 8-mesh molecular sieves are normally used in gas phase applications, while the 8 to 12-mesh type is common in liquid phase applications. The pellet forms of the 3A, 4A, 5A and 13X sieves are suitable for specialized applications.

Applications

- Drying of unsaturated hydrocarbons (e.g. ethylene, propylene)

- 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.

Packing 1 kg/pack
Note Drying or regeneration is recommended before first use to remove the absorbed moisture and organic molecular.  Heat the molecular sieves to 175-260 °C purging with a carrier gas.
