Pellet Shape Zeolite 3A Molecular Sieve High Adsorption Rate For
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; And
this maximizes lifetime when dehydrating such molecules.
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 liquid alcohol
5) Drying of refrigerants
1), 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.
2), 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.
3), The outlet concentrations on a pressure swing process will
depend on the gas present, and on the conditions of the process.
To avoid damp and pre-adsorption of organic before running, or must
to be reactivated.
