High Adsorption Rate Pellet Shape Zeolite 3A Molecular Sieve For
JINCHENG Molecular Sieve type 3A is an alkali metal
alumino-silicate; it is thepotassium 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 Chemical Formula:
0.45 K2O . 0.55 Na2O . Al2O3 . 2 SiO2 . 4.5H2O
By carton box, each box 25kg net, wooden pallet with wrapped.
By steel drum, each drum 150kg net, wooden pallet with wrapped.
1) Drying of unsaturated hydrocarbons (e. G. Ethylene, propylene,
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
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.
