Product Description

Adsorbent beads 3a molecular sieve sphere 1.7-2.5 mm 3a zeolite desiccant for ethanol dehydration  


Chemxin Molecular Sieve type 3A is an alkali metal aluminosilicate; 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.

Ethylene adsorption (‰) ≤3.0 ≤3.0 ≤3.0 ≤3.0
Water content (%) ≤1.5 ≤1.5 ≤1.5 ≤1.5
Typical Chemical Formula

0.4K2O . 0.6Na2O . Al2O3 . 2SiO2 . 4.5 H2O (SiO2 : Al2O3 ≈2)

Typical Application

a) Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien)
b) Cracked Gas Drying
c) Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.
d) Drying of highly polar compounds, such as methanol and ethanol
e) Drying of liquid alcohol
f) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.
g) Drying of CNG.


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.

Chemxin insulating glass desiccant can deeply co-adsorb the resident moisture and organics in Insulating Glass, keep the IG clear and transparent even at very low temperature. More important, it can successfully avoid the tremendous air pressure outbalance placed on the glasses, which was superposed by seasons of day-night temperature changing and the ensuring air adsorption and adsorption function of common IG desiccant. Thus it resolves the problems of windows distortion caused by IG inflation and shrink, expanded the life span of IG windows

Typical Application:

For insulated glass adsorption at the same time insulating glass of water and organic residues, so that the insulating glass, even in very low temperatures remained bright and clean and transparent, at the same time be able to reduce the insulating glass full season as a result of the temperature difference between day and night and are subject to great changes both within and outside the powerful Pressure on the poor, solve common insulating glass desiccant easy to make hollow glass or expansion and contraction caused by broken distort the issue, fully extend the life of insulating glass.
