Molecular sieve 3a
Molecular Sieve 3Ais 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.
Typical Chemical Formula 0.4K2O 0.6Na2O Al2O3 2.OSiO2 4.5H2O SiO2 : Al2O3≈2

Typical Application
1)Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadiene)
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
5) Drying of liquid alcohol
6) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.
7)Drying of refrigerants
RegenerationMolecular sieve Type 3A 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 ******0°C is required. A properly regenerated molecular sieve can give moisture dew points below ***0°C. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.
