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.

2. 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.

3. 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.

4. Attention:

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