3A Molecular Sieve

Short Description:

1.Product Description Molecular Sieve type 3A is an alkali metal alumino-silicate; it is the potassium form of the typ A crystal structure. Type 3A 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; and this maximises lifetime when dehydrating such molecules. 2.Typical Chemical Formula: 0.4K2O  0.6Na2O  Al2O3  2.OSiO2  4.5H2O 3.Technical Paramet...

    4.Typical Application

    1.Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien)
    2.Cracked Gas Drying
    3.Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.
    4.Drying of  highly polar compounds, such as methanol and ethanol
    5.Drying of liquid alcohol with Z3-01 / 1-2 mm beads 
    6.Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.
    7.Drying of refrigerants (e.g. R22, R134a etc)
