Molecular Sieve 3A is an alkali metal alumina-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.
Advantages of molecular sieve 3A
1) With uniform pore size and high surface area, thermal stability, high absorption capacity, high strength characteristics.
2) By molecules of different size and shape, select the adsorption, meaning that just absorb less than the pore size of 3A molecular sieve.(never adsorb any molecular larger than 3A)
2) For small polar molecules and unsaturated molecules, with selective absorption properties, the greater the polarity, the higher the unsaturation, the selective adsorption is stronger.
4) Has strong water absorption. Even at the higher temperature,Greater airspeed and the lower content of water, still have the relatively high water absorption capacity
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, such as methanol 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 refrigerants
