3-5mm Molecular Sieves 3A, 4A, 5A, 13X, 13X APG Promotion
4A Molecular sieves, also called the zeolite 4a molecular sieve. It can adsorb any molecular diameter less than 4 Å
Mainly used in deep desiccation of cracked petroleum gases, such as ethylene, propylene, butadiene, acetylene and natural gas, and of polar liquid, such as ethanol, LPG and solvent.
Speciafication of 4A molecular sieve :
|Size ratio up to grade||%||≥96||≥96|
|Static water adsorption||%||≥21.5||≥21.5|
Psa molecular sieve applications as follows
Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien)
Cracked Gas Drying
Drying of natural gas
Drying of highly polar compounds, such as methanol and ethanol
Drying of liquid alcohol
Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.
Drying of refrigerants
