3A Molecular Sieve for Methonal Drying with High Adsorption Beads 3-5mm
DESCRIPTION:
3A Zeolite Molecular Sieve 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 liquid alcohol
2) Drying of unsaturated hydrocarbons (e. G. Ethylene, propylene, butadien)
3) Drying of refrigerants
4) Cracked Gas Drying
5) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.
6) Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.
7) Drying of highly polar compounds, such as methanol and ethanol

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.
SIZE:
3A - Zeolites 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 1.6", 3.2".
ATTENTION:
To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
