Molecular Sieve
Molecular Sieve 3Ais 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
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
******0°C is required. A properly regenerated molecular sieve can
give moisture dew points below ***0°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 **2 mm, (*0x*8 mesh)
**3 mm, (8x*2 mesh)
, 2.**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..
