Original product description
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 0.6. Na2O Al2O3 2.
OSiO2 4.5H2O SiO2: Al2O3 ≈ 2 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 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.
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.
