    Molecular Sieve 5A Desiccant is shipped in 330 pound Steel Drums. Molecular sieve is a sodium aluminosilicate. An alkali metal alumino-silicate, in the calcium form of the Type A crystal structure. Type 5A will adsorb molecules with critical diameters up to 5 Å angstroms. All molecules which can be adsorbed on Molecular Sieve types 3A and 4A can be adsorbed on Type 5A.

    Applications: Used for the dehydration and purification of various hydrocarbon and non-hydrocarbon gas and liquid streams. It is used for the separation of straight and branched chain hydrocarbons, sweetening and drying of natural gases and the production of high purity hydrogen.

    Regeneration: Type 5A molecular sieve can be regeneratedfor re-use by purging or evacuating at elevated temperatures. The degree of regeneration (water removal) is dependent on the temperature and humidity of the purge gas. Note: Using a dry purge gas at an inlet temperature of 200-350°C and a pressure of 0.3 ~ 0.5 kg/cm², heat the molecular sieve bed. As the temperature in outlet reaches 150 ~ 180°C, let the bed cool off.

    Handling and Storage: Molecular sieve must be stored in a dry location (relative humidity <90%) to prevent re-adsorption of water. Opened packages should be resealed to prevent contamination of the product. Whenever possible, rotate stock to use oldest material first.


    1. Uniform retention capacity
    Moisture retention (pounds of water adsorbed per pound of desiccant) does not change appreciably if the air or gas is not saturated. It also keeps its moisture retention properties over a wider range of operating temperatures.

    2. Round bead shape
    Round shape has high abrasion resistance and results in lower pressure drop than extruded molecular sieve.
