  • Molecular Sieve 3a For Double Glazing - China

    price: contact company for price

    Molecular sieve 3a

    Molecular Sieve 3A is an alkali metal alumino- silicate; it

    is the potassium form of the type 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 maximizes lifetime

    when dehydrating such molecules.

    Typical Chemical Formula 0.4K2O 0.6Na2O Al2O3 2. OSiO2 4.5H2O

    SiO2 : Al2O3 ≈ 2

    Typical Application

    1) Drying of unsaturated hydrocarbons ( e. g. ethylene,

    propylene, butadiene)

    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

    5) Drying of liquid alcohol

    6) Static, ( non- regenerative) dehydration of insulating

    glass units, whether air filled or gas- filled.

    7) Drying of refrigerants

    Regeneration Molecular sieve Type 3A can be regenerated by

    either heating in the case of thermal swing processes; or by

    lowering the pressure in the case of pressure swing

    processes. To remove moisture from a 3A molecular sieve, a

    temperature of 200- 230°C is required. A properly

    regenerated molecular sieve can give moisture dew points

    below - 100°C. The outlet concentrations on a pressure swing

    process will depend on the gas present, and on the

    conditions of the process.

    Attention To avoid damp and pre- adsorption of organic before

    running, or must to be reactivated
