Good Absorption 3a Molecular Sieve Desiccant Using Oil Industry Drying
3A Molecular Sieve, 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.
It has the advantages of faster adsorption speed, more regeneration times, higher crushing strength, stronger anti-pollution ability, greater utilization efficiency and longer service life.
Chemical Molecular Formula : 0.4K2O·0.6Na2O·Al2O3·2SiO2··4.5H2O. (SiO2 : Al2O3 ≈2).

a) Be mainly used for the drying of petroleum cracking gas such as ethylene, propylene, butadiene and others.
b) Drying of highly polar compounds, such as methanol and ethanol.
c) Drying of air.
d) Drying of natural gas and methane gas.
1. The product cannot be exposed in the open air and should be stored in dry condition with air-proof package.
2. The product should be regenerated after a certain period of adsorption. The appropriate regenerated temperature would be better below 350°C.
