        3A Molecular Sieve

        3A Molecular Sieve

        3A molecular sieve is potassium exchange, the pore size is 3A, can be called potassium molecular sieve; It is mainly used to adsorb water, because the diameter of water molecules is less than 3A; Most of the gas is greater than 3A, so 3A molecular sieve will not adsorb any molecule with a diameter greater than 3A, and it is an adsorption material necessary for deep drying, refining and polymerization of gas and liquid phase in the petroleum and chemical industry.
        Main application areas:

        • Drying of various liquids (such as methanol and ethanol).
        • Drying of air and drying of insulating glass.
        • Drying of refrigerant.
        • Drying of natural gas and methane gas.
        • Drying of unsaturated hydrocarbons and cracking gas, ethylene, acetylene, propylene, butadiene.
        • Drying of food-grade CO2.
        • As a catalyst carrier, adsorption of water molecules in oil.
