3A molecular sieve

Molecular Sieve type 3A is an alkali metal aluminum-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.

Introduction
Molecular Sieve type 3A is an alkali metal aluminum-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
K72Na48[(AlO2)12(SiO2)12].XH2O

Application
Molecular Sieve 3A is mainly used to remove moisture and can be applied to liquefied and gaseous materials on the whole.
The main uses are as follows.

1)Drying of refrigerants (e.g. R22, R134a etc)

2)Removing moisture in paint and PU Plastic
3)Drying of natural gas
4)Cracked Gas Drying.
5)Static dehydration of insulating glass units, whether air filled or gas-filled.
6)Drying of highly polar compounds, such as methanol and ethanol. 
7)Drying of unsaturated hydrocarbons (e.g. ethylene, propylene). 
8)Drying of olefins drying, ethanol, etc.

Regeneration
Molecular Sieve 3A can be revived for reuse and the required factors for revival are temperature and pressure. To remove the adsorbed moisture and other materials, the revival condition shall be set up considering the features of target material and processing environment. The general revival temperature of Molecular Sieve 3A is about 250℃ and it should not surpass 300℃ at maximum.
Package
Prevention against moisture, let it away from water, lube oil, acid and alkali material. Package by 25 kg carton, steel drum, jumbo bag are available.
