XINTAO 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 maximises lifetime when dehydrating such molecules.

Typical
Application
1)Â Drying of
unsaturated hydrocarbons (e.g. ethylene, propylene, butadien)
2)Â Cracked Gas Drying
3)Â Drying of natural gas, if COS minimization is essential,
or a minimum co-adsorption of hydrocarbons is required.
4)Â Drying of highly polar compounds, such as methanol and
ethanol
5)Â Drying of liquid alcohol
6)Â Static, (non-regenerative) dehydration of insulating
glass units, whether air filled or gas-filled.
7)Â Drying of refrigerants
 Â
Regeneration
XINTAO
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)Â and as powder,
and in pellet 1.6, 3.2.
Â
Attention
To avoid
damp and pre-adsorption of organic before running, or must to be
reactivated.
