3A Molecular Sieve

Chemxin Molecular Sieve type 3A is an alkali metal alumina-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 Application

                    a) Drying of unsaturated    hydrocarbons (e.g. ethylene, propylene, butadien)
b) Cracked Gas Drying

                    c) Drying of natural gas, if COS minimization is essential, or a minimum   

                       co-adsorption of hydrocarbons is required.
d) Drying of highly polar compounds, such as methanol and ethanol
e) Drying of liquid alcohol
f) Static, (non-regenerative) dehydration of insulating glass units, whether    air filled or gas-filled.
g) Drying of CNG.



2. Regeneration:

    Chemxin 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.


3. Size: 
3A - Zeolite are available in beads of 1-2 mm(10x18 mesh), 2-3 mm(8x12 mesh), 2.5-5 mm(4x8 mesh) and as powder, and in pellet 1.6mm, 3.2mm.


4. Attention:
To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
