Applications 
● Unsaturated hydrocarbons (ethylene, propylene, butadiene, acetylene ...) drying 
● Petroleum cracked gas drying
● Ethanol drying 
● Cracked gas drying in ethylene industry
● Natural gas dehydration and preventing formation of COS
● Methanol drying
● Air filled insulated glass units static drying
● Food-grade carbon dioxide drying
● Benzene, toluene and xylol drying

Attention
The 3a zeolite can't be exposed in the open air and should be stored in dry condition with air-proof package. 

The zeolite 3a molecular sieve for ethanol drying can be regenerated after a certain period of adsorption. The appropriate regenerated temperature would be better below 350℃.
