molecuar sieve

Type 3A has an effecttive pore openg of about 3 angstoms(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.

Formula

0.45K2O. 0.55 Na2O. Al2O3.2SiO2.4.5H2O

SiO2:Al2O3≈ 2

Application

1.Drying of unsaturated hydrocarbons(eg:ehy;ene,propylene,butadien)
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.

Size

3A-Zeolites are available in beads of 1-2mm,(10X18mesh),2-3mm(8x12mesh),2.5-5mm(4x8 mesh) and as powder,and in pellet 1.6",3.2"

Attention

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