Introduction :
Molecular Sieve type 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
Drying of unsaturated hydrocarbons (e.g. ethylene, propylene,
butadien)  Cracked Gas Drying  Drying of natural gas,
if COS minimization is essential, or a minimum co-adsorption
of hydrocarbons is required. Â Drying of highly polar
compounds, such as methanol and ethanol  Drying of liquid
alcohol  Static, (non-regenerative) dehydration of insulating
glass units, whether air filled or gas-filled. Â 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 1.6â€, 3.2â€.
 Attention
To avoid damp and pre-adsorption of organic before running, or must
to be reactivated.
