Product Description

3A Molecular Sieve 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 maximizes lifetime when dehydrating such molecules.

Application/Usage

1) Drying of unsaturated hydrocarbons (e.g. ethylene, butadien)

2) Cracked Gas Drying  

3) Drying if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.

4) Drying of highly polar compounds

5) Drying of liquid alcohol

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

7) Drying of refrigerants

Regenation
Molecular sieve can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case of pressure swing processes. 
To remove moisture from a 3A molecular sieve, a temperature of 200-230°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.

Attention
Attention To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
