molecular sieve for remove water co2 h2s

Chemxin molecular sieve with high adsorption performance methanol drying

Product Description

Chemxin Molecular Sieve type 3A is an alkali metal alumina-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.

Regeneration:


Chemxin 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.


Size:
3A - Zeolite are available in beads of 1-2 mm(10x18 mesh), 2-3 mm(8x12 mesh), 2.5-5 mm(4x8 mesh) and as powder, and
in pellet 1.6mm, 3.2mm.


Attention:
To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
