JINCHENG Molecular Sieve type 3A is an alkali metal
alumino-silicate.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.

1) Drying of natural gas, if COS minimization is essential, or a
minimum co-adsorption of hydrocarbons is required.
2 Drying of highly polar compounds, such as methanol and ethanol
3 Drying of liquid alcohol
4) Static, (non-regenerative) dehydration of insulating glass
units, whether air filled or gas-filled.
5) Drying of refrigerants
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.
