    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℃.
